BIOMETRIC is an app for independent training and nutrition management. It calculates calories, keeps a diary, stores personal records and body measurements, provides an exercise library with videos, and creates workout programs.
You can use it two ways: as a mini app inside Telegram, or as a standalone app on iOS and Android. The features are the same either way — this is one app in two windows, not two different products. Created by trainer Vladimir Zagadov.
The app does NOT provide medical services and does not replace a doctor.
Everything it shows is guidance on training and nutrition, not a medical prescription. This also applies to the interpretation of blood test results: the app explains the numbers on your test report in plain language and suggests what you may want to ask your doctor, but it does not diagnose conditions or prescribe treatment. Treatment decisions must be made only by a doctor who has examined you.
Do not postpone seeing a doctor because the app says that something is "within the normal range." If you feel unwell, see a doctor, not the app.
Blood test interpretation and some recommendations are generated by artificial intelligence. It can make mistakes. Check important information with a qualified professional.
Training with weights involves a risk of injury. You train independently and are responsible for your own safety.
Consult a doctor before starting a training program, especially if you have a chronic medical condition, are recovering from an injury, are pregnant, or are over 45 and have not exercised for a long time.
Stop exercising and seek help if you experience acute pain, dizziness, chest pain, or shortness of breath.
The weights, sets, and calorie targets suggested by the app are estimates based on general formulas and the information you provide. They cannot take everything into account. Listen to your body: it knows more about you than any formula does.
Temporarily, for the launch period: the app may only be used by people aged 18 or older. We ask for date of birth before saving the profile, and if it shows the person is under 18, we do not create a full account and do not save medical data, photos, or the profile.
Family access (a child's profile under a legal representative's consent — a parent, adoptive parent, or guardian) is already designed and will return here once it reopens. See section 7 of the Privacy Policy for how it will work and what happens to profiles already registered under 18.
There is no separate password for the app — sign-in is confirmed by whichever way you use it. In Telegram, that's your Telegram account: do not give anyone access to it, since anyone who can open your Telegram account will also be able to access your data in the app. In the standalone iOS or Android app, sign-in is confirmed by a key tied to that specific phone (you can unlink it in one tap under "Danger Zone") — the same caution applies: do not hand over a phone with the app signed in and expect your data to stay yours.
The data you enter must belong to you. Do not upload another person's blood test results, photos, or medical information without that person's consent.
If you follow a trainer's link and confirm the connection, the trainer can see your workouts, personal records, body measurements, nutrition, and activity. That is the purpose of trainer mode: the trainer cannot coach you without seeing your information.
Connecting with a trainer is your choice. You can disconnect from the trainer in the app at any time, and the trainer will immediately lose access to your data.
While you are paired with a trainer, you can message each other in the app (Community → Messages). Only the two of you can see the conversation. You can delete your own message for both of you. If either side removes the pairing, the conversation closes. You can report the other person's message with a long press; it will be sent to us for review. Messaging is not available under 18.
In Telegram. Some features require payment: food photo analysis, blood test analysis, and AI-generated workouts. The diary, personal records, body measurements, ready-made plans, and exercise library with videos remain free.
Payments are made using Telegram Stars. Payments are processed by Telegram, not by us: we do not see or store your payment card information.
A monthly subscription renews automatically until you cancel it. You can cancel it directly in Telegram through your list of subscriptions. An annual subscription is paid for with a single payment and does not renew automatically.
Refunds are governed by Telegram's rules. We will refund your payment if the app failed to work due to a problem on our side — contact us, and we will handle it fairly.
Prices may change. Any period you have already paid for will not be affected.
In the standalone iOS and Android app. Everything is currently free — there are no paid features there yet. If a paid tier is introduced, it will be through Apple's or Google's own in-app purchase systems (App Store / Google Play), not Telegram Stars: their rules do not allow payment outside their own systems. We will announce this in the app in advance rather than switching it on silently.
Do not attempt to access another person's data, interfere with or hack the app, or download the exercise and video library for resale. The videos, texts, programs, and training methods belong to the author. Use them for yourself, not for resale.
If someone attempts to break the app or access another person's data, their access will be terminated without a refund. This is the only reason we will terminate access ourselves.
The app is provided "as is." We work to make sure it functions correctly and produces accurate calculations, but we cannot promise that it will never make mistakes or become temporarily unavailable.
We are not responsible for injuries or other harm resulting from training, decisions made based on the app's recommendations, or consequences resulting from your decision not to see a doctor.
You can permanently delete everything at any time using the button in the app: "Profile" → "Danger Zone" → "Delete Account." This permanently erases your data without a backup copy.
If these Terms change in a material way, the app will show them to you again and ask for your consent again. The date of the latest update appears at the top of this document.
