Terms of Service

What Nonna is

Nonna (Telegram bot @NonnaCaloriesBot) estimates calories, protein, fat and carbs from photos, voice notes and text you send, keeps a food diary and sends you coaching messages. The service is provided by Rustem (contact: zx2504@gmail.com).

Not medical advice

Nonna is a wellness tool, not a medical service. Estimates from photos are approximate. Nonna does not diagnose, treat or prevent any disease. If you are pregnant, under 18, have an eating disorder, diabetes or any other medical condition, talk to a doctor before changing your diet.

Free trial and payments

• The first days are free (the length of the trial is shown in the bot).
• After that, access is paid in Telegram Stars: 1 месяц: 199 Telegram Stars, 1 год: 1490 Telegram Stars.
• The monthly plan is a Telegram Stars subscription: it renews automatically every 30 days until you cancel. Cancel anytime in Telegram: Settings → My Stars. After cancelling, access stays until the end of the paid period.
• The yearly plan is a one-time payment and does not renew.
• Payments are processed by Telegram. We never see your card details.

Refunds

If something went wrong with a payment, write /paysupport in the bot or email zx2504@gmail.com within 14 days. We will refund unused Stars when the service did not work as described.

Fair use

Please use Nonna for your own food diary. We may limit the number of photo analyses per day to keep the service running for everyone.

Your data

How we handle your data is described in the Privacy Policy: https://sufiev-ai.ru/nonna/privacy. You can delete everything at any time with the /delete command.

Changes

We may update these terms. The date at the top shows the latest version. Continuing to use the bot means you accept the current terms.
