Privacy Policy (Charlier)

Last updated: 2026-02-26

Charlier is a cardistry practice and progress-tracking app. It is designed to work primarily with data stored locally on your device.

1) Data We Collect

Charlier does not collect personal data on any developer-controlled servers.

2) Data Stored on Your Device

Charlier stores all app content locally on your device, such as:

Moves you create (names, notes, categories, metadata)
Practice history and progress (XP, levels, streaks, activity/heatmap-style history)
Optional media you add (such as videos/photos you import)

This data stays on-device unless you export it.

3) Backups and Export/Import

Charlier provides optional backup/export features (for example, exporting a backup file you can store yourself). If you export backups, you control where you save them (for example iCloud Drive, local files, or another storage provider). Charlier does not automatically upload your data to any developer-controlled server.

4) Notifications

If you enable reminders, Charlier uses local notifications on your device. Notification permissions are controlled by iOS Settings.

5) Third-Party Services

Charlier does not share your data with third parties.

6) Children’s Privacy

Charlier is not intended to knowingly collect personal data from children. The app does not request personal identifiers by default.
