Privacy Policy

Last updated: 4 Eylül 2026

This policy explains what data the Tunatrophy mobile app processes and why. Questions: info@tunatrophy.com.

In short: we do not use your data for advertising, we do not sell it and we do not share it with ad networks. You can delete your account from inside the app; deleting it also deletes your training, nutrition and coach data.

Who processes it

The data controller is Tunatrophy. Contact: info@tunatrophy.com.

What we collect

Account: email address, display name and which sign-in method you use (email/password or Sign in with Apple). We never hold your password; authentication is handled by Google Firebase Authentication.
Setup and profile: birth year, height, weight, goal, experience level, how many days and minutes a week you can train, where you train, available equipment, the lifts you report, areas where you report pain, reminder times, unit and tone preference.
Training log: sessions, exercises, weight, reps and difficulty (RPE) per set, completion times.
Measurements and progress: your bodyweight entries, estimated and tested strength values, and the decisions behind plan changes.
Nutrition log: meals you enter, calories and macros, your daily adherence mark and the targets you set yourself.
Coach conversations: what you write to the AI coach, its replies and the lasting notes kept with your approval.
Security log: when actions such as sign-in, sign-out, account deletion and plan setup happened, together with the IP address and the browser/device user agent. It holds no measurement values or training data — only the name of the action and its time.

We do not collect an advertising identifier, we use no third-party advertising or analytics SDKs, and we do not process location data.

Why we process it

To build your training program and calculate loads.
To show your progress and keep your history.
So the AI coach can answer using your own data.
To send reminders, if you chose them.
To keep your account safe and limit abuse.

Who we share it with

We do not sell data. Only the providers needed to run the service are used:

Google Firebase Authentication — authentication. Your email address and sign-in details are processed there.
OpenAI — the AI coach. The messages you write and the profile/plan summary needed to answer them are sent to OpenAI. This data is not used to train their models and coach conversations are sent so that they are not retained by the provider.
Server hosting — the app's API and database run on a server we rent.
Expo (EAS Update) — delivery of app updates. When the device checks for an update it sends version and platform information; no account or health data is sent.

If we are legally required to (for example by a court order) we may have to share the minimum data necessary.

How long we keep it

We keep your data while your account exists; comparing your history is the product's whole job. When you delete your account, your training, nutrition, measurement and coach data, along with your identity record, are deleted. The security log (which account, which action, when — including the IP) is retained.

Your rights

Deletion: in the app, Profile → Delete account. This cannot be undone.
Access and a copy: you can see your records inside the app. If you want a copy of everything, write to info@tunatrophy.com and we will send it once we have verified your identity. In-app export does not exist yet.
Correction: you can edit your profile and entries in the app.
Coach memory: the notes the coach keeps about you are listed under Coach → Memory and can be deleted one by one.

Health data

Data such as the weight, sleep and pain you enter is health data and is used only to produce training and nutrition suggestions for you. It is not used for ad targeting, not turned into a marketing profile and not sold to third parties.

Children

Tunatrophy is for people aged 18 and over only. Setup asks you to confirm your age and rejects a birth year under 18.

Security

Connections are encrypted with TLS, authentication goes through Firebase, and only the application's own narrowly-scoped database user can reach the database. No system is perfect; if you notice a problem, write to info@tunatrophy.com.

Changes

If this policy changes, the date on this page is updated; for an important change we will also tell you inside the app.
