Processing on your device
Game progress and statistics
Your progress in the current puzzle, your solved days, streaks and settings are stored only on your iPhone. The daily puzzles are calculated inside the app from the date and are not downloaded from the internet.
Reminders
The daily reminder is a local notification scheduled by Tröpfchen on your device. No data is sent to the developer.
Sharing your result
When you share your result, the iOS share sheet opens. The text is only passed on to the app and the people you choose yourself.
Purchase
Tröpfchen is purchased entirely through Apple's App Store. The developer receives no payment or personal data. Apple's privacy policy applies: apple.com/legal/privacy.
Your rights
As the developer does not collect any personal data, no data about you is held by the developer. Deleting the app removes all game data from your device. For privacy questions, contact me at the email address above. You also have the right to lodge a complaint with a data protection authority.
