Privacy policy

Last updated : 13 juillet 2026

Atlo ("the application") is a personal sports and nutrition coach. This policy explains what data the application processes, why, and the choices available to you. For any questions: contact@atlo.health.

Data we process

  • Account: your email address (or the identifier provided by Apple / Google during login).
  • Profile: age, sex, height, weight, country, goals, activity level, and the settings you enter during onboarding.
  • Health & fitness: the measurements you choose to sync from Apple Health (HealthKit) or Health Connect (heart rate, HRV, sleep, SpO2, calories, steps, weight, body fat, etc.), as well as your logged workouts and meals.
  • Coach content: messages, food photos and voice recordings you send to the coach to get a response.
  • Approximate location (optional): if you allow it, your position rounded to ~1 km is sent to Open-Meteo to know the local temperature and adapt your hydration goal. It is neither stored nor linked to your identity.
  • Purchases: your Premium subscription status (managed by Apple/RevenueCat). We never see your payment information.

Why we process this data

Only to operate the application: calculate your recovery scores and calorie needs, generate personalized programs and advice, and display your history. Your health data is used exclusively for these functions, never for advertising.

The application does not track your activity for advertising purposes and does not include any third-party advertising or analytics SDKs. No data is sold.

HealthKit / Health Connect commitment: data read from Apple Health or Health Connect is never sold, never used for advertising, never used for targeting, and never shared with third parties for purposes other than operating the application.

Subprocessors

Supabase, database hosting and authentication. Your data is stored there securely.

Google Gemini (Google AI), processes the content you send to the coach (text, food photos, voice transcription) to generate a response. This content is sent at the time of the request and is not used to train advertising models.

Purchases

The Premium subscription is managed by the App Store via Apple. Atlo does not receive or store your payment information.

Where data is stored, and for how long

Your data is stored in a secure Supabase database (encryption in transit and at rest), accessible only by your account through per-user isolation rules (RLS). On the device, your session is encrypted (key in the iOS keychain / Android Keystore).

Data is retained as long as your account exists. Upon account deletion, all data is immediately and permanently erased. Content sent to the AI coach (text, photos, audio) is transmitted to Google Gemini at the time of the request and is not retained by us beyond the conversation history visible in the application.

Retention and deletion

You can delete your account directly in the application (Settings → Delete my account). Deletion is permanent and erases your account and all associated data (profile, workouts, meals, measurements, coach history). You can also log out at any time.

Your rights

In accordance with the GDPR, you can access your data, correct it, export it or delete it. Deletion is available in one tap in the application; for any other request, write to contact@atlo.health.

Children

Atlo is not intended for individuals under 16 years of age and does not knowingly collect their data.
