Last updated: 14 October 2026

This policy follows the Swiss Federal Act on Data Protection (FADP) and, where applicable, the EU General Data Protection Regulation (GDPR).

2. In short

• Rappel needs no account and no sign-in.
• Your learning progress, cards and settings stay on your device.
• We collect no analytics, show no ads and use no trackers.
• Purchases are handled by Apple. We never see your name or payment details.

3. What data does the app process?

3.1 Learning data on your device

The app stores locally on your iPhone: your learning progress (lessons, FSRS review schedule, answers), your game state in «Les Hauts» (places, finds, crystals) and your settings (volume, daily goal, language). This data does not leave your device and is not sent to us. It is part of your device backup (iCloud or computer) if you have backups turned on; Apple's terms apply to those backups.
