Privacy Policy

1. Who we are

KanFit is a fitness tracking app. This policy explains what we collect, why we collect it, the legal basis for processing it, and what control you have over it.

2. Data we collect

Account data: name, email, gender (optional) and password, handled by our authentication provider — we never see your password.

Fitness data: workouts, sets, weights, programmes, body measurements, meals, water intake and scanned products.

Support data: messages you send to coach support and support tickets you open.

Technical data: device type, app version, and crash or error diagnostics used to fix problems.

3. Legal basis for processing

We process account and technical data to perform our contract with you (providing the app and its features).

We process fitness, body measurement and nutrition data based on your explicit consent, given when you first enter this data, since it can qualify as health-related data under Article 9 GDPR. You may withdraw this consent at any time from Settings → Privacy, which will stop new collection and let you delete existing data.

We process technical/diagnostic data based on our legitimate interest in keeping the app secure and functional.

4. Camera and barcode scanning

The camera is used only while the scanner is open, to read a product barcode on your device. Camera frames are never uploaded or stored.

Only the decoded barcode number is sent to the Open Food Facts database to fetch product nutrition values.

5. How we use your data

To show your dashboard, progress, streaks and analytics.

To generate nutrition targets and programme recommendations based on your goal.

To answer coach support messages and send notifications you have enabled.

To keep the app working offline by caching your last synced data on your device.

6. Offline storage on your device

KanFit stores your most recent data locally so the app keeps working without internet. You can clear it any time from Settings → Privacy.

7. Data retention

We keep your data for as long as your account is active. If you delete your account, your workouts, meals, measurements, body data and chat history are deleted from our systems within 30 days, except where we are legally required to retain certain records for longer.

8. Advertising

The free plan may show in-app promotions managed by KanFit. Premium removes all ads. We do not sell your personal data to advertisers.

9. Sharing and international transfers

We share data only with the services needed to run KanFit: our cloud database and authentication provider, and Open Food Facts for barcode lookups.

Where any of these providers process data outside the European Economic Area, we ensure appropriate safeguards are in place, such as Standard Contractual Clauses.

We may disclose data if legally required, or to protect the safety of our users.

10. Security

Data is transmitted over encrypted connections and protected by per-user access rules, so one account cannot read another account's data.

11. Your rights

Under GDPR, you have the right to access, correct, delete, restrict, or export your data, and to object to or withdraw consent for certain processing.

Access and edit your data inside the app at any time.

Delete your account from Settings — your workouts, meals, measurements and messages are removed.

Export a progress report to share with a coach or physician.

Turn notifications on or off in Settings → Preferences.

You also have the right to lodge a complaint with a data protection supervisory authority, such as your local Datenschutzbehörde, if you believe your data has been mishandled.

12. Children

KanFit is not intended for children under 16 and we do not knowingly collect their data.

13. Contact

For any privacy question or to exercise your rights, contact us through Settings → Help Center.

14. Changes

We will announce material changes to this policy inside the app.
