SleepyCalc — Data Deletion
Last updated: September 8, 2025
What data does SleepyCalc store?
- Mobile app (Android): Alarm settings (time, days), preferences (language, theme), and history are stored locally on your device (e.g., SQLite/local storage). We do not receive or host these data on our servers.
- Website (optional): If you submit a contact form/email, we process your message solely to respond.
- Advertising & diagnostics: The mobile app uses Google AdMob, which may collect an Advertising ID (AD_ID), device information, ad interactions (impressions/clicks), and diagnostics for fraud prevention and performance. If enabled in the future, the website may show ads via Google AdSense.
Automatic deletion
Local app data (alarms, preferences, history) are removed automatically when you:
- Uninstall the SleepyCalc app from your device, or
- Clear the app’s storage via Android Settings → Apps → SleepyCalc → Storage & cache → Clear storage.
Advertising/analytics data follow Google’s own retention policies. You can reset or remove your Advertising ID in Android Settings → Google → Ads (or device privacy settings), and manage ad personalization in your Google account.

- Local app data: Deleted by you when uninstalling or clearing app storage on your device.
- Website contact messages: Deleted on verified request, unless retention is required for legal or security reasons.
- Advertising/analytics data: Controlled by Google according to their policies; manage via your device and Google account settings.
