Privacy policy

1. What data

• Profile: goal, sex, age, height, weight, target weight, experience, training days, style, the machines in your gym; optionally your name.
• Training and health records: sets, weights, habits (steps, water, sleep, protein), body measurements, workout logs.
• Progress photos — only if you upload them.
• Account: email and password (the password is stored in hashed form; we can't see it) — only if you sign up.
• Notification subscription — only if you turn notifications on (your browser's technical endpoint and your training days).
• Technical error logs: error message, page, browser type and app version.
• Activity log — if you sign in: sign-up, sign-in/sign-out time and method, which settings changed (not their values), workout completion, account deletion/restore. Used for security, support and abuse prevention.
• Anonymous visit statistics (Vercel Web Analytics): which pages are viewed. No cookies are used and IP addresses are not stored.

Data such as body weight and measurements is sensitive (health) data. We process it only with your consent — because you enter it into the app — and you can delete it at any time.

2. Where it is stored

• If you don't sign in: everything stays only on your device (in browser storage). Nothing reaches us.
• If you sign in: your records are stored in the Supabase cloud database in the European Union (Frankfurt, Germany). The connection is encrypted; in the database each user can see only their own data (row-level security).
• Photos are kept in private storage — only you can see them, with your own account.
• The app is hosted on the Vercel platform.

3. Why we use it

• To calculate your personal program, weight suggestions, calories and progress.
• To sync your records between your devices.
• To send reminder notifications if you want them.
• To find and fix errors and improve the app.

We don't sell your data or share it for advertising. Only the technical service providers above (Supabase, Vercel) store it on our behalf.

4. How long we keep it

• While your account is active — your records are kept.
• If you delete your account: your records are kept in an archive for 30 days so you can restore them if you change your mind. After 30 days the account and all personal data are permanently deleted.
• Photos and notification subscriptions are deleted immediately when you request deletion.
• Error logs are kept for 30 days.
• Activity log is kept for 180 days; when your account is fully deleted, your email is removed from it.
• When an account is deleted, only anonymous statistics are kept: goal, sex, age group (e.g. 30–39), start/target/last weight, number of workouts and weeks, style. This record contains no email, name, account ID or anything else that could identify you.

5. Your rights

• View and download: Progress → “Download data” — all your records in one file.
• Correct: in Settings, at any time.
• Delete: Settings → “Delete account”.
• Use without an account: all core features of the app work without signing up.
• You can turn off notifications and opt out of statistics at any time.

6. Age limit

The app is intended for people aged 14 and over. Users under 18 should use it after consulting a parent or doctor.

7. Changes and contact

If this policy changes, we will update the date above; we will announce significant changes in the app. For questions or data requests, contact: inside the app (Settings → Account) — a separate email address will be added soon.
