Sytno Terms of Use

Effective date: August 13, 2026

These Terms govern your use of the Sytno mobile app (the “App”) and related services - the @SytnoAppBot Telegram bot and our server. By installing or using the App you accept these Terms. If you do not agree with them, do not use the App.

The App is developed and provided by an individual; contact details are at the bottom of this page. How we handle personal data is described in a separate document - the Privacy Policy.

1. What the App does

Sytno helps you keep a food diary: it recognises food from a photo, counts calories and macros, breaks down ingredient labels, gives AI-assisted nutrition tips and shows your statistics.

The App is not a medical device and does not provide medical services. Calorie and macro calculations, day reviews, label breakdowns and assistant answers are informational and for reference only. They are not a diagnosis, a prescription, or dietary or medical advice.

Food data comes from open sources and from AI models and may be inaccurate. Photo recognition estimates portion weight and composition approximately. Do not make health, treatment or dietary decisions based on the App alone. If you have a medical condition, are pregnant, take medication, or plan a significant change to your diet, consult a doctor.

The label breakdown shows our own categories (“everyday ingredient”, “worth limiting”, “questionable additive”) and a reference score. It is not a statement that a product is harmful, not a safety assessment, and not a claim that any manufacturer has breached any regulation.

2. Account

Some features - photo analysis, the assistant, label breakdown, friends, subscriptions - require an account. You register with Sign in with Apple or Google.

By using the App you confirm that you are at least 13 years old. The App is not intended for children under 13.

You are responsible for keeping access to the Apple or Google account you sign in with. One person, one account: creating multiple accounts to obtain free trials again is not allowed.

Public nickname. For the Friends feature you choose a nickname visible to other users. It must not contain insults, hate, pornography, advertising or other people’s personal data, and must not impersonate another person or Sytno. We may reset such a nickname without notice.

3. Premium

Some features require a paid Sytno Premium subscription. What Premium includes is listed in the App on the “Sytno Premium” screen and may change: features may be added, and individual features may move from the free tier to the paid one. We announce significant changes in the App’s News section.

Payment methods. Premium is paid through the @SytnoAppBot Telegram bot - Telegram Stars or a bank card via a payment provider - or, where available, as an in-app purchase in the App Store. We never receive or store your card details; they are handled by Apple or the payment provider.

Term. A subscription is granted for a term (a month or a year) and runs until the date shown in the App. Payment through the Telegram bot is one-off and does not renew automatically: when the term ends, Premium simply stops. If the subscription was bought as an App Store in-app purchase, it renews automatically under Apple’s rules and can be turned off in your Apple ID settings.

Refunds. Refunds are handled under the rules of the platform you paid through (Apple, Telegram, the payment provider) and under applicable law. For refund questions, contact us at the address below.

Promo codes and bonuses. Promo codes, referral bonuses and the Telegram-linking bonus are granted at our discretion, cannot be exchanged for money, and may be revoked if abused (for example, by registering fake accounts).

Limits. Free use has limits (the number of photo analyses and assistant questions), and paid use has reasonable daily caps that protect the service from abuse. Current values are shown in the App and may be revised.

4. Acceptable use

You must not:

• circumvent limits or paid restrictions, including by re-registering, automating requests or interfering with the App or the server;
• misuse the AI features - the assistant answers questions about nutrition and the App, and may decline unrelated requests;
• upload or send unlawful content, abuse other users or our support, or impersonate anyone;
• attempt to access other people’s accounts or data, disrupt the service, or probe it for vulnerabilities without our consent;
• copy, decompile or distribute the App or its parts, or use our materials commercially without permission.

If you breach these rules we may restrict access to certain features or block the account - for serious breaches, without prior warning.

5. Your content

Your food diary, photos and body details belong to you and are stored on your device. By sending us a nickname, a support message or a survey answer, you allow us to store and use them to run the service: to reply to you, improve the App and resolve disputes. We do not publish your messages and do not share them with third parties for marketing.

6. Rights in the App

The App, its source code, name, logo and design belong to us and are protected by law. These Terms grant you no rights in them beyond the right to use the App on these terms. Product data is partly taken from the Open Food Facts database and used under the ODbL licence, as stated in the App.

7. Limitation of liability

The App is provided “as is”. We do not warrant that it will run without interruption or error, that calculations and AI answers will be accurate, or that the service will always be available: some features depend on third-party services (OpenAI, Apple, Google, Telegram, Open Food Facts) and on connectivity.

We are not liable for decisions you make based on the App’s data, nor for health consequences. To the extent permitted by law, our liability is limited to the amount you paid for Premium in the preceding 12 months.

Nothing in this section limits rights that cannot be limited under applicable law, including consumer rights.

8. Termination

You may stop using the App at any time and delete your account right in the App: Profile → “Delete account”. Deleting your account does not automatically cancel a subscription bought through the App Store - turn it off in your Apple ID settings; any Premium time already paid for is lost on deletion and is not refunded.

We may suspend or discontinue the service, giving notice in the App, and may block an account that breaches section 4.

9. Changes to these Terms

We may update these Terms. The current version is always available at this link, with the effective date at the top. We announce significant changes in the App. By continuing to use the App after changes take effect, you accept the new version.

10. Governing law and disputes

These Terms are governed by the law of the Russian Federation, except where mandatory rules of your country of residence say otherwise. The parties will try to resolve disputes by correspondence; failing agreement, a dispute is heard under the jurisdiction rules set by law.
