Terms for the SofiaYuzu app — App Store and Google Play

Last updated: 2 November 2026

These terms are the agreement between you and us about the SofiaYuzu app when you subscribe in the App Store or on Google Play. They cover your account, your subscription, and what you can expect from us, and they apply wherever you use the app — in our iOS or Android app or in the browser at sofiayuzu.com/app. If you subscribed on sofiayuzu.com, the website version of these terms applies instead.

Please read them. By creating an account you accept them.

1. Who you are dealing with

The app is run by:

Sofiia Serhiivna Hetman (Гетьман Софія Сергіївна)
Individual entrepreneur (Ukrainian фізична особа-підприємець, ФОП), 3rd tax group
Record in the Unified State Register of Ukraine: 2011600000000112030
Registered address: Microdistrict 2, building 46, Lozova, Kharkiv region, 64606, Ukraine
Phone: +380 93 118 22 96 · Email: admin@sofiayuzu.com

A ФОП is a registered business run by a natural person, not a company. So the person behind the app is Sofia herself, under her own name.

Who sold you the subscription.

We are the supplier of the service itself, and these terms cover that part. Apple or Google charges you, applies the tax and issues your receipt. We never see or store your card number.

We do not cancel your subscription or refund it ourselves. The billing is Apple's or Google's: you cancel it in your device's settings, and refunds follow the store's rules, not ours. We will always tell you exactly where to go, and we will help with anything that is about the service rather than the payment. Where the law obliges us to give your money back — we removed a feature you paid for, we closed the service, or we found out you are under 16 — we pay you ourselves and we will write and ask you where to send it.

If Apple's or Google's checkout says something about your rights that is less favourable to you than what this page says, what this page says applies to what we provide.

2. Who can use the app

You must be at least 16 years old to have an account. We ask for your date of birth when you sign up and we check it on our side, not only in the browser. We do not have a younger age band and we do not have a parental-consent route.

If we find out that an account belongs to someone under 16, we suspend it immediately, delete the health data straight away rather than on our normal schedule, and refund everything that was ever paid on that account, to the payment method it came from — however long the account existed and whoever paid. We do not ask for proof of age and we do not argue about how much of the service was used. The account is closed as part of this, and we keep a dated note that we did it.

If somebody else tells us an account belongs to a child — a parent, for example — we neither delete the account on their word alone nor ignore them. We write to the address on the account, ask for the date of birth to be confirmed, and give 14 days to answer. While we wait, no new health data can be added to that account, but reading and exporting keep working. If the answer confirms the account holder is under 16, or nobody answers, we do what the paragraph above says.

Where the app is available. We do not offer the app or the cookbooks in Russia, Belarus, Kazakhstan or Uzbekistan, we do not direct our services at those countries, and we do not accept sign-ups or orders from there.

The app is for your own personal use. One account per person. Please give us information that is true — the calorie and nutrient targets are calculated from your body data, so wrong numbers give you wrong targets.

3. Your account

You sign in through Clerk, our sign-in provider. Keep your password to yourself and turn on two-factor authentication if you can. Tell us at admin@sofiayuzu.com if you think someone else has got into your account.

You are responsible for what happens under your account while you are the one in control of it.

We can suspend or close an account if it is used to break these terms, to abuse the service or other people, or to commit fraud — and we can act immediately when the abuse is serious. Where we reasonably can, we will tell you first and give you a chance to fix it: we close a paid account outright only for serious or fraudulent abuse, and for anything smaller you get a warning and a chance to put it right. If we close your account, you can still ask for a copy of your data and you can still ask us to delete it. See Delete your account.

You can close your account yourself at any time, in Profile → Your data → Delete my account and data. Deletion is explained in full on that page — including the fact that closing your account does not by itself stop an App Store or Google Play subscription, which only you can cancel in your device's settings (section 5).

4. What the app is

What the app is, in one line: software for logging and charting your own records. The targets it shows are arithmetic applied to published population reference values (section 10). The app does not give medical advice, it does not treat anything, and nothing in it is a consultation.

In practice, it is a place to log and see your own health and food data: meals and their nutrients, water, weight, sleep, steps, workouts, menstrual cycle, blood test results, mood, medications and supplements, notes, and files you upload. It draws charts and writes plain-language summaries of your own logs.

The plans. What each one includes in full is set out on the plans page in the app and at sofiayuzu.com/app; in short:

• Free — food diary (search, barcode, entered by hand) with calories, protein, fat and carbohydrates, water and weight.
• Basic — food diary and nutrients, water, weight and measurements, sleep, steps, workouts.
• Pro — adds cycle, mood and well-being, medications and supplements, lab results and medical documents, body photos, bowel records, full vitamins and minerals, insights.

What it is not is set out in section 10. Read that section before you rely on anything the app tells you.

5. Your subscription

The Free plan costs nothing and needs no card. A Free account that nobody signs into for 6 months is erased, after a warning email a month before (see “What happens to your data after your subscription ends” below). Basic and Pro are paid subscriptions, and the rest of this section is about them.

Plans and prices. Two paid plans — Basic and Pro. What each one includes is set out in section 4 and on the plans page in the app; the price for your country is shown there and again by the store before you confirm. Yearly plans cost less per month than monthly ones. In the EU and the UK every price you see already includes VAT; in the United States sales tax, where it applies, is added by the store.

The 3-day trial.

• The trial is available on both plans, Basic and Pro, as the store's introductory offer. Whether you can take it is decided by Apple or Google, under their own rules for introductory offers.
• Your payment details stay with Apple or Google, never with us.
• Nothing is charged during those 3 days.
• At the end of day 3 the trial ends, the subscription starts at the price you were shown when you signed up, and the store charges you automatically — unless you cancel before then.

We email you on day 2. Two days before the trial ends we send you a reminder that says when the trial ends, exactly how much you will be charged, how often it will repeat, and where to cancel. Apple or Google also sends its own notices under its own rules. Ours is in addition to theirs, not instead of them.

On the day you subscribe we email you a confirmation of the contract — the day your trial starts, or the day the paid subscription starts if you subscribe without a trial. It states your plan, the price, the date the trial ends and the date and amount of the first charge. Keep it: it is your written record of what you agreed to.

Renewal. After the first charge the subscription renews automatically until you cancel — monthly plans every month, yearly plans as described next.

Yearly plans. A yearly plan renews for another year until you switch auto-renew off in your device's subscription settings. The store's rules on renewals apply, and so does any protection the law where you live gives you.

Before a yearly plan renews we remind you three times — by email three months, one month and one week before the renewal date. Each reminder gives the date, the exact amount, and a link that cancels in one click. If we fail to send those reminders, the law where you live may let you end the contract and have your money back; nothing here limits that.

Your price does not change while your subscription runs. For as long as your subscription continues without a break, you keep the price you signed up at, even when we raise prices for new subscribers. If we ever do have to change your price, we tell you by email at least 30 days before it would apply and you can cancel before it does; if we tell you later than that, the new price skips a renewal and starts at the one after.

Changing plan.

• Moving up (Basic → Pro): you make the change in your device's subscription settings, and the store applies it straight away under its own rules.
• Moving down (Pro → Basic) takes effect at your next renewal, under the store's rules. You keep what you paid for until the period you have already paid for ends.
• After you move down, everything you already logged stays visible. You simply cannot add new entries in the parts of the app that belong to the plan you left; those buttons lead to the plans page instead. Nothing is deleted, and the export works on every plan.

If a payment fails. Apple or Google retries it under its own rules, and the grace period is the store's, not ours. If your plan stops while the store is retrying, your account works on the Free plan until the payment goes through, and your data stays as it is. You are never charged twice for the same period.

How to cancel. In your device's settings:

• In the iOS app: Settings → your name → Subscriptions.
• In the Android app: Play Store → Payments and subscriptions → Subscriptions.

We do not cancel an App Store or Google Play subscription for you. You cancel it yourself, in the settings above, and you keep everything you paid for until the end of the period.

There is no cancellation fee.

What cancelling does. You keep full access until the end of the period you have already paid for. Nothing is charged after that, and your account moves to the Free plan.

Deleting your account is not the same as cancelling. Deleting your account does not stop the charges. You have to cancel in your device's subscription settings as well, or the store will keep billing you. We show you this warning before you delete.

What happens to your data after your subscription ends — because you cancelled, a trial ended without a payment, or the payment retries ran out.

• Your account moves to the Free plan and everything you logged stays. The Free features keep working; what you logged with paid features stays saved but locked, and it opens again as soon as you subscribe, at no charge beyond the price of the subscription itself.
• If you do not sign in for 6 months while on the Free plan, we erase your account and data from the live service, apart from payment and tax records we are legally required to keep and the record of your consents. We email you a month before, and signing in once is enough to keep the account. Your sign-in stays — the email and password you log in with — so that you can come back; ask us and we delete it too. A copy can remain in our rolling database backups for a short window afterwards — this is explained in full in the App privacy policy.

You can take a copy of your data at any time, on any plan, the Free plan included, in Profile → Your data → Download my data (JSON). The export is a JSON file of everything you logged; original lab PDFs download one at a time from the record they belong to, and the App privacy policy lists everything else we hold about you — ask us and we will send you that too.

If you subscribed inside the iOS app. Apple requires us to spell this out, and it is accurate:

• Payment is charged to your Apple Account when you confirm the purchase.
• The subscription renews automatically unless auto-renew is switched off at least 24 hours before the end of the current period. Your account is charged for the renewal within 24 hours before the current period ends, at the price shown for your plan.
• You can manage the subscription and switch auto-renew off at any time after purchase, in your Account Settings on the device.
• If you buy a subscription before a free trial ends, the unused part of the trial is forfeited.
• Apple is not responsible for the app or its content and gives no warranty for it. Support for the app itself comes from us, at admin@sofiayuzu.com. Apple and its subsidiaries are third-party beneficiaries of these terms as they apply to your use of the iOS app, and Apple has the right to enforce them against you.

If you subscribed inside the Android app, the same shape applies under Google Play's rules: the subscription renews automatically until you cancel it in Play Store → Payments and subscriptions → Subscriptions, and Google charges and receipts you.

How the contract is made, in technical terms

Some laws — Ukrainian law where we are registered, and EU law where many of you are — require us to spell out the mechanics of an online contract. Here they are.

1. The steps. You choose a plan → you create an account with your email address and a password → you give your date of birth and tick the consent boxes → you confirm the purchase with Apple or Google in the app. The contract exists from the moment the store confirms your purchase.
2. Correcting a mistake. Before you confirm, every step can be gone back to and every field can be changed. After you confirm, write to admin@sofiayuzu.com and we will correct anything that was entered wrong — including cancelling an order placed by mistake.
3. The language of the contract. The contract is concluded in the language you were reading these terms in when you subscribed. In Ukraine that is Ukrainian.
4. Your copy, and where it lives. On the day you subscribe we email you a confirmation with your plan, the price, the trial end date and the date and amount of the first charge. We keep every version of these terms: the current one is always at this address, and we will send you the exact version your purchase was made under if you ask. Ask us at admin@sofiayuzu.com and we will also send you a PDF you can print.
5. No electronic signature is needed. Ticking the box and confirming the order is how the contract is accepted. We do not ask for and do not use qualified electronic signatures.

6. Refunds and your right to withdraw

Refunds and the 14-day right to withdraw are Apple's or Google's. They sold you the subscription, so you ask them, under their own rules — not us. This is the same wherever you live, including the EU, the UK and Ukraine. If the problem is with the service rather than the payment, write to us as well and we will help.

Where the law obliges us to give your money back, we pay it ourselves — we will write and ask you where to send it. That covers these cases:

• We change or remove something you were paying for and you leave because of it. We refund the whole unused part of your period, within 14 days (section 14).
• We close the service. We refund every paid period that has not been used (section 14).
• You withdraw your consent to us handling your health data. The tracker cannot run without it, so this brings the service to an end for you. We refund the unused part of your paid period, counted from the day you withdraw the consent, within 14 days — withdrawing a consent must never cost you more than cancelling would.
• We find out you were under 16. We give you all of your money back, however long the account existed (section 2).

7. What you put into the app, and what we may do with it

Everything you log stays yours. Your notes, your photos, your lab PDFs, your entries — we do not claim ownership of any of it.

To run the service we need your permission to handle it. You give us a limited licence to store, encrypt, back up, process and display your content back to you, and to pass it to the services that make the app work — nothing more. That licence exists only so the app can function, it is not exclusive, we make no money from it separately, and it ends when your content is deleted.

In plain terms, that permission covers: keeping your lab PDFs and body photos so you can see them again; sending a photo or a document to our AI provider when you ask the app to read it; and showing your own data back to you in charts and summaries.

One exception, and only if you choose it: a product you add to a barcode. Once it passes our check, you let us keep its name and nutrition facts in our shared food database and show them to everyone who scans that barcode — also after you delete the product or your account. Nothing that identifies you goes with it.

We do not sell your content, we do not use it for advertising, and we do not use it to train AI models.

Please do not upload anything you have no right to upload, and nothing illegal.

8. The leaderboard, your nickname, and the season prize

There is a leaderboard. It lives in the streak sheet in the app, where everyone can see it — there is no separate page — and it shows the top ten by points. Taking part is optional and comes with the paid plans: you join by tapping Join in the streak sheet and choosing a nickname, and you can leave at any time in the same place — your nickname disappears from the board immediately and your streak keeps counting. On the Free plan you are not shown on the board; your nickname and points are kept, and you are back on it when you subscribe.

The only things other people ever see are the nickname you choose (3–20 characters) and your points. Your name, your email, your photos, your measurements and everything else you log stay private, always. You can change the nickname whenever you like in the streak sheet — pick one that does not identify you if you would rather stay anonymous.

How points work. You get 1 point for every closed day (see section 9 for what a closed day is) and 10 extra points for every calendar week, Monday to Sunday, in which you closed all seven days with food. Days covered by a freeze keep your streak alive but do not earn the weekly bonus. Points are counted from the start of the season, and the streak sheet shows your points, the board and the day the season ends.

Nicknames are visible to other people, so there are rules. Nothing obscene, hateful, harassing or impersonating anyone. You can report a nickname right from the leaderboard, and you can write to admin@sofiayuzu.com about anything you see there; a person reads every report. We remove what breaks these rules, normally within 24 hours of being told, and we can take a persistent offender off the board for good.

The season prize. The leaderboard runs in seasons of one year. The first year runs from the day the app opens to the public — we will announce that date in the app and add it here — to the same date the following year, and every later year follows on from there. When a season ends, whoever has the most points gets one free month of the plan they are on, added the same way as the streak reward (section 9). If several people are level at the top, all of them get the prize — this is a result, not a draw, and there is no random element anywhere in it. Being new means fewer points available to you: someone who joins a month before the season ends can collect at most about a month's worth of points and will not out-score someone who has been closing days all year. We would rather say that here than explain it afterwards. Winners are told by email and shown in the app.

9. The streak, freezes, and the streak reward

You build a streak by closing days in the app. A closed day is any day with at least one food entry — a photo, a barcode, a voice note or something typed in. Future dates do not count.

• Freezes. You have three freezes in every calendar month. They cover missed days: if you miss a day and you still have a freeze for that month, the app uses one automatically and your streak survives. You can also freeze today or days ahead yourself in the streak sheet — for a trip or a holiday — and undo it as long as the day has not passed. Log food on a frozen day and the freeze goes back to you. Freezes do not carry over: whatever you have not used when the month ends is gone, and three new ones are there for the next month. A frozen day keeps the streak alive but does not add a day to it.
• Missed days that no freeze can cover reset the streak to zero. Your closed days and points stay.
• Each full year of streak — 365 closed days without a break — earns you one month of your current paid plan, free. Without a running subscription — on the Free plan — the month is not credited and does not carry over.

You do not have to ask and you do not have to write to us. Each time you complete a full year — at 365 days, at 730 and so on — the app awards it and moves your next billing date 30 days later: we push your renewal date in the App Store or on Google Play back by 30 days. You will see the new date in your device's subscription settings.

You earn one free month for each full year of unbroken streak. It has no cash value and it cannot be transferred or sold. Streaks built by faking entries, by scripts, or across more than one account do not count, and we may reset a streak we can see was manipulated.

Changing the reward. We can change the reward and the yearly prize, or stop offering them, for a period that has not started yet, and we announce any such change by email before that period begins. We do not change the rules of a period that is already running, and a streak you have already completed is never taken away.

10. Health disclaimer — read this one

The SofiaYuzu app is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Consult a healthcare professional for medical advice.

More specifically:

• The app is for general wellness and self-tracking. It is not a medical service and using it is not a consultation.
• When the AI reads a lab report, it transcribes the values. It does not interpret them. It copies the numbers, the units and the reference ranges from your document so you can see them over time. It does not tell you what they mean, it does not say whether a result is dangerous, and it does not give a diagnosis. Only your doctor can do that.
• AI transcription can be wrong. It can misread a decimal point, a unit or a whole line. Everything it produces is a draft for you to check, your original document remains the authoritative version, and you should compare the two before relying on a number — and always take the original, not the app, to your doctor. Section 11 explains the AI features in full.
• Nothing in the app — targets, charts, summaries — replaces advice from a doctor, a pharmacist, or a state-registered dietitian.
• Talk to a professional before you change your diet or exercise if you are under treatment for any condition, if you take medication, if you have or have had an eating disorder, or if you have diabetes, kidney, liver or heart disease.
• Pregnancy and breastfeeding. The cycle tracker has a pregnancy mode and you are welcome to use it. But the targets and reference values in the app are not calculated for pregnancy or breastfeeding — during that time they need to be agreed with your doctor or midwife. When you turn the mode on, the app suggests switching your goal to maintenance and turning weight-loss targets off.

There is a floor, and we will not move it.

Whatever goal you set, the app will not accept:

• a daily energy target below 1,200 kcal;
• a rate of weight loss faster than 1 kg (2 lb) a week;
• a goal weight below a BMI of 18.5 for your height.

If you try, the app explains why and offers the nearest figure it will accept. Targets below these belong in the care of a doctor, not in an app, and no setting here unlocks them. This is a deliberate limit, not a bug.

If food, weight or your body is becoming difficult, please talk to someone. In an emergency, call your local emergency number. Otherwise, findahelpline.com lists free and confidential helplines in most of the countries we serve. If the app notices a pattern it is not equipped to support, it will show you where to find help — it will never lock you out of your own data. We are a tracking app. We are not a treatment service, and nobody is watching your entries in real time.

Where the numbers come from. Your daily energy target is calculated with the Mifflin-St Jeor equation and an activity multiplier. Protein, fat, carbohydrate and micronutrient reference values follow the NIH Dietary Reference Intakes. The sodium limit follows the World Health Organization recommendation of less than 2 g of sodium (about 5 g of salt) a day. These are population averages. They are a starting point, not a prescription for you personally.

Nutrient values for foods come from public food databases and from product labels. They are estimates and they can be wrong. Check the label if a number matters to you — for an allergy, it always matters.

11. The AI features

Some parts of the app use an artificial-intelligence system, and we would rather you knew exactly where. You are interacting with an AI system in these places:

• turning a meal you describe or dictate into a list of foods;
• reading a photo of a meal, a food label, a supplement or a medicine package;
• looking up the general pharmacological class of a medicine you type in;
• reading a lab report, doctor's note or prescription you upload;
• reading the numbers off a steps or sleep screenshot;
• suggesting a type and colour from a bowel-movement photo;
• and when you write to our support address or message us on social media. The first line of support is an AI assistant, and it says so at the start of every conversation; if your account is on the Free plan, a person reads your email instead. It handles account and subscription questions. It hands anything else to a person, and it never decides a request about your data — a copy, a correction, a deletion or the withdrawal of a consent always goes to a human being, whatever the assistant said first.

On the Free plan none of the features in the app above is used: they are part of Basic and Pro.

Three rules apply to all of them:

1. Everything the AI produces is a draft. It is shown to you before anything is saved, you can edit it or throw it away, and nothing is written to your diary that you did not accept.
2. AI output can be incomplete or factually wrong. Models of this kind can misread a number, invent a plausible-looking value, or skip a line. You are the check on it. Where the AI read a document you uploaded, that document is the authoritative version, not what the app shows — compare them before you rely on a value.
3. No decision about you is made automatically. Nothing in the app decides anything with legal or similarly significant effect for you, so the rules in Article 22 GDPR on solely automated decision-making do not apply. If that ever changes, we will tell you before it does, not after.

The App privacy policy section 6 lists exactly what is sent for each feature and who processes it. You can switch the AI features off in Profile → Your data → Consents & privacy. Every one of them has a hand-entry alternative.

12. What you must not do

Do not: use the app to break the law; try to break into it, into other people's accounts, or into the systems behind it; scrape it, copy its database or resell what is in it; upload malware; automate access with bots or scripts; take it apart to build a competing product; or use it to harass anyone.

13. Our content

The app, its design, its text, its recipe and food data, its icons and its code belong to us or to our licensors. You may use them inside the app, for yourself. You may not copy, republish or resell them.

Some food data comes from Open Food Facts, used under the Open Database License (ODbL), from the USDA FoodData Central database, which is in the public domain, from the Ciqual food composition table of ANSES (the French Agency for Food, Environmental and Occupational Health & Safety), used under the Open Licence 2.0 (Licence Ouverte / Etalab 2.0), and from web pages that our AI finds for barcodes whose nutrition facts are in none of these databases. The app shows the source where that data is used.

14. Availability, and when we may change the app

We work to keep the app running, but we do not promise it will never be down. Fixing bugs, improving how something looks and adding new things are not changes to what you bought, and we do those as we go.

Changing or removing something you are already paying for is different, and we have tied our own hands.

We may change or remove a feature that is part of your paid plan only where one of these five things has happened:

1. a third party has withdrawn or discontinued an interface, service or data source the feature depends on;
2. the law requires the change;
3. the security of the service or of your data requires it;
4. Apple or Google requires it as a condition of the app staying in their stores;
5. an integration with another platform comes to an end.

What we will not do: we will not remove a feature because keeping it is inconvenient or expensive for us, and we will not move a feature you already pay for into a more expensive plan.

If we do make such a change:

• we tell you in good time before it happens, and we tell you by email — not by a push notification, a banner or a changelog entry. If we have not emailed you, notice has not been given and the periods below have not started running;
• the change costs you nothing;
• where the change is more than minor and makes the app measurably worse for you, you may end your subscription free of charge within 30 days of whichever comes later: our email, or the change itself;
• if you do, we refund the part of the period you paid for and did not use, within 14 days, with nothing deducted — we pay you directly and we will write and ask you where to send it.

You do not have to prove anything to use this right, and using it costs you nothing.

If we ever stop offering the app altogether, we stop selling subscriptions on the day the decision is made, so that nobody buys a year of something that is ending. We then tell you by email three months, one month and one week before the service closes, we cancel every subscription, and we refund every paid period that has not been used. The export keeps working for the whole notice period and for a while after the service closes — people keep years of records here and we are not going to shut the door on them. After that the data is deleted. It is not sold and it is not passed on as an asset by itself.

If the business is sold as a going concern, your data moves with it. The App privacy policy explains what we tell you before that happens, what the buyer has to promise, and how long you have to take your data out or delete it.

15. Our liability

Nothing in these terms limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else that the law does not allow us to limit or exclude. Your rights as a consumer under the law of your own country are not affected by anything here.

Beyond that: we are liable for loss that is a foreseeable result of us breaking these terms, and for the remedies the law gives you when a digital service is not what it should be — putting it right, a reduction in price, or ending the contract with your money back. We are not liable for loss that is not foreseeable, for business losses, or for data you lost because you never exported it. This applies in the same way to the AI features in section 11 — those results are drafts for you to check, and acting on an unchecked one is not something we can answer for.

Where our liability can be capped, it is capped at what you paid us in the 12 months before the problem — but that cap never applies to the refunds we promise you in sections 6 and 14, and it never applies to anything your own consumer law says we cannot cap.

Two things we are not going to hide behind. If you are hurt because we were careless, the first paragraph of this section governs and nothing else in it helps us — we are not excluding that, whatever label the harm is given. And we do not disclaim the service just because it runs on somebody else's machines: your device and your network are yours, but Clerk, our hosting provider and our AI provider are ours. If the service is not what it should be because of one of them, that is between us and them — not between us and you. Outages of the app stores themselves, and of your own device or network, are outside our control.

16. Which law applies, and where you can sue

These terms are governed by the law of Ukraine.

If you are a consumer, that takes nothing away from you. You keep the protection of the mandatory consumer rules of the country where you live, and where those rules and these terms disagree, those rules win. You can bring a claim against us in the courts of the country where you live, and we will only bring proceedings against you in the courts of the country where you live. Nothing here obliges you to travel, to arbitrate, or to sue in Ukraine.

Complaints. Please write to admin@sofiayuzu.com first — we answer every complaint. If we cannot sort it out between us, the consumer protection body and the courts of your own country are open to you, and for anything about a payment, an invoice or a chargeback you can also go to whoever sold you the subscription. We are not currently signed up to an alternative dispute resolution scheme and we are not obliged to be.

17. Languages

The English text of this page is the one we write and update first.

Where we have published a version in another language, that version is the one that applies to you and you can rely on it. If it differs from the English one, the meaning that is more favourable to you applies. Anything that was more favourable to you in an older translation still applies to what you did while that translation was the published one — we do not get to improve our position by being slow to translate. For users in Ukraine the Ukrainian version applies as required by Ukrainian law.

Today this page is published in English, German, Spanish, French, Polish, Portuguese, Russian and Ukrainian. Each version shows when it was last updated. If we have not published a version in the language you read, the English text applies. If you spot a difference between two versions, write to admin@sofiayuzu.com and we will fix whatever is wrong.

18. Changes to these terms

We may update these terms. If a change matters to you — price, billing, your rights, how we handle your content — we tell you by email at least 30 days before it takes effect, and you can cancel before then. Small corrections, like fixing a typo or a broken link, we just make. The date at the top always shows the current version.

A change never applies to a period you have already paid for. What you agreed to when you paid is what governs that period, until it ends.

19. Contact

Phone: +380 93 118 22 96 — the line takes messages and points you to email.
Email: admin@sofiayuzu.com — the fast way to reach us; we answer in writing.

An AI assistant reads that mailbox first and answers routine things — cancelling a web subscription, questions about how the app works — and it says so at the start of every conversation. A person reads everything else, and every request about your data goes to a person. Please do not send us lab results or other health documents by email: put them in the app. If one arrives, we delete the message.

Write to us in English, German, Spanish, French, Polish, Portuguese, Russian or Ukrainian.

We usually answer within a week. Billing disputes and anything complex can take up to two weeks. Requests about your personal data are answered within one month (45 days if you are making a request under Washington State law), and any refund we owe you is paid within 14 days of your notice.

For what we do with your data, see the App privacy policy and the Consumer Health Data Privacy Policy. To delete your account, see Delete your account. For our business details, see the Legal notice.
