Privacy Policy — My Food

Last updated: 12 June 2026

My Food (“the app”, “we”) is a nutrition tracker for iOS. This policy explains what we collect, why, and your choices. We keep it short because the app collects little.

Who the data controller is

The app is operated by CHAO HSUAN LIN. For any privacy question, contact: **r[email protected]**

What we collect

Account information. When you sign in with Apple or Google, we receive a user identifier and (if you allow it) your name and email address. We use this only to create and secure your account and to sync your data across your devices.

Nutrition data you enter. The food you log, your custom/favorite foods, your daily calorie and macro goals, training/rest mode, and water intake.

Apple Health (HealthKit) — optional, off by default. If you turn on Apple Health in Settings, the app:

• writes the calories, protein, carbohydrate, fat, and water you log to Apple Health, and
• reads the same dietary categories to keep your totals consistent.

Health data is processed only on your device and in your private account database to power the app’s features. It is never used for advertising or marketing, and is never sold or shared with third parties.

How your data is stored

• Your data is stored on your device and, once you sign in, in your private account on Supabase (our backend provider). Row-level security ensures each account can only ever access its own data.
• We do not sell your data, show third-party ads, or use third-party analytics/tracking SDKs.

Third parties we use

• Supabase — hosts the database and authentication for your account.
• Apple / Google — only to let you sign in (we never see your password).
• Apple HealthKit — only on your device, and only if you enable it.

Your choices and rights

• Disable Health sync anytime in Profile → Apple Health.
• Sign out anytime in Profile.
