Privacy Policy – Body Metrics

Last updated: July 2026

Body Metrics ("the app") is developed by MrNick Apps. This privacy policy explains what data the app collects, how it is used, and your rights regarding that data.

1. Data We Collect

The app collects the following data:

• Body measurements you enter manually (weight, neck, chest, biceps, forearm, waist, hips, thigh, calf) and their dates
• Email address — only if you choose to create an account to sync your data across devices. Account creation is optional; the app works fully without it.
• Anonymous device identifier — assigned automatically for data storage

We do not collect your name, phone number, location, or any other personally identifiable information.

2. Authentication

By default, the app uses anonymous authentication via Firebase — no login required. Optionally, you can create an account with an email address and password to sync your measurements across devices. Your password is handled securely by Firebase Authentication and is never stored by us directly.

3. Data Storage

Your measurement data is stored securely in Google Firebase Firestore, associated with your user ID. Data is stored in the European Union (europe-west1) and encrypted in transit.

4. Data Sharing

We do not sell, share, or disclose your data to any third parties, except as required by the infrastructure services listed below.

5. Third-Party Services

• Google Firebase (Authentication & Firestore) – Privacy Policy
• RevenueCat (in-app purchase management) – Privacy Policy

6. Deleting Your Data

You have full control over your data and can delete it at any time:

Delete individual measurements

Long-press any entry in the history log within the app to delete it.

Delete your account and all associated data (in-app)

If you are signed in, you can delete your account directly from within the app:

Your account and all associated measurement data will be permanently deleted immediately.

Delete your account by email (alternative)

If you cannot access the app, you can also request deletion by email:

What is deleted: your account, email address, all body measurements, and all settings. What is kept: nothing — all data is fully removed. Anonymous purchase records may be retained by Google Play as required for financial/legal compliance.

7. Children's Privacy

Body Metrics is intended for users aged 18 and over. We do not knowingly collect data from children.

8. Changes to This Policy

We may update this privacy policy from time to time. Changes will be posted on this page with an updated date.
