  • Device information: Basic device type and operating system version for compatibility and bug fixing purposes.

Third-Party Services

The App uses the following third-party services:

  • RevenueCat: For managing in-app subscriptions. RevenueCat may collect purchase-related data as described in their privacy policy.
  • Open-Meteo: For providing weather data in morning reports. Open-Meteo receives your approximate location (if you grant permission) to deliver local weather information. See their privacy policy.

How We Use Your Information

We use the information we collect to:

  • Provide and maintain the App
  • Improve and personalize your experience
  • Process subscription transactions
  • Deliver weather and morning report features
  • Fix bugs and improve performance

Data Storage and Security

  • Alarm settings, puzzle progress, and streaks are stored locally on your device.
  • We do not maintain user accounts or store personal data on our servers.
  • Subscription data is managed by Apple and RevenueCat.

Your Choices

  • Location: You can deny or revoke location permission at any time in your device settings. Weather features will be unavailable without location access.
  • Notifications: You can manage alarm and notification permissions in your device settings.
  • Data deletion: Since data is stored locally, uninstalling the App removes all local data.

Children’s Privacy
