PowerTimer respects your privacy. The app does not collect, transmit or store any information that ties to you.
The app collects anonymous installation and usage info as provided by the App Store. You may opt out by going to Settings → Privacy → Anaytics & Improvements, and turn off Share Analytics.
PowerTimer uses RevenueCat to manage in-app purchases. RevenueCat generates a unique identifier that is stored locally. When you make or restore a purchase, RevenueCat obtains the App Store receipt ID. This ID can associate different device to the same user, but doesn’t disclose to us (or to RevenueCat) about any personal information such as your Apple ID email.
