Privacy Policy

Effective date: 2025-09-14

WeightGuardian helps you track your weight. We keep things simple and transparent.

What we store

• On your device: your weight entries, height, goals, reminders, and settings are saved locally in a private database.
• Optional Google Drive backup: if you sign in and choose to back up, we save an app snapshot (JSON) to your Google Drive appDataFolder (hidden). You can remove it any time from Drive.

What we do not collect

• No account with us, no servers—your data does not leave your device unless you export/share or back up to Drive.
• No names, emails, or contact lists from your device.

Advertising (AdMob)

We show a small banner ad. Ads may use device identifiers and coarse location to measure performance and prevent fraud. In some regions (e.g., EEA), you can choose whether to receive personalized ads. You can disable ads in the app (“Remove ads”).

Learn more: Google Ad Policies.

Exports & backups

• Export/Share: you can export CSV/JSON. These files are under your control.
• Restore: you can import a previous CSV/JSON into the app.

Data deletion

• On device: delete entries in the app, or uninstall the app to remove the local database.
• Backups: delete your CSV/JSON files and remove the app’s backup from Google Drive.

Children

The app is for general audiences and is not directed to children. We do not knowingly collect data from children.

Security

Your data stays on your device unless you export or back up. For Drive backups, we use your Google account and Google’s security.

Changes

We may update this policy as the app evolves. We will update the “Effective date” above.
