Privacy Policy

1. What we collect

WeekFit collects only what's needed to run the app:

• An account identifier from Apple or Google (used to recognize you on return).
• Your email address (or Apple's hidden relay email, if you choose that).
• The training data you create: plans, workouts, sets, personal records, custom exercises and templates.
• Your in-app preferences (weight unit, default rest, sound, screen-on).

Apple Health

Apple Health integration is optional and only active if you turn it on. When enabled, WeekFit:

• Reads your body weight, heart rate, and active energy — to show workout stats and estimate load for bodyweight exercises.
• Saves your completed strength workouts (with their heart rate and energy) to Apple Health, so they appear in the Health and Fitness apps.

Health data stays on your device and in Apple Health. It is never uploaded to our backend, shared with third parties, sold, or used for advertising. You can turn this off anytime in WeekFit's settings, or manage access in iPhone Settings → Privacy & Security → Health.

2. Where your data lives

Your data is stored on your device and synced to our backend at Supabase (Postgres database hosted in the United States). Sync is over HTTPS, and the database is encrypted at rest by the provider.

We don't sell your training data or use it to serve ads. We share only the limited data needed for the services described below.

3. Third parties and AI plan generation

The following services help WeekFit work and receive only the data needed for their function:

• Apple — Sign in with Apple identity check.
• Google — Sign in with Google identity check.
• Supabase — authentication, database hosting, and secure routing of AI plan requests. Acts as a data processor on our behalf.
• OpenAI or DeepSeek — optional AI plan generation. OpenAI is used outside the China App Store; DeepSeek is used for the China App Store.

When you tap Generate plan, WeekFit sends your training goal, focus, experience, environment and equipment, selected training days, session duration, app language, optional notes, and a list of eligible WeekFit exercises. We don't send your name, email address, or account identifier to the AI provider. The information is used to generate the requested plan. Don't include sensitive personal information or detailed medical history in your notes.

4. Account deletion

You can delete your account anytime from Settings → Profile → Delete Account.

When you tap Delete:

• Your local data is erased from this device immediately.
• Your training data on our backend is deleted within seconds.
• Your authentication record is removed shortly after.

If you're offline at the time, the cloud-side deletion may be deferred until your device next reaches the network.

5. Children

WeekFit is not intended for children under 13. We do not knowingly collect personal information from children under 13.

6. Changes to this policy

We may update this policy as the app evolves. Material changes will be reflected in the effective date above. Please review periodically.
