What ProSleep does #
ProSleep is a sleep cycle calculator. You enter a time, and the app calculates optimal bedtimes or wake times based on 90-minute ultradian sleep cycles. Optionally, premium users can set a system alarm from within the app.
Data we collect #
We collect no personal information.
ProSleep does not require an account, does not connect to our servers, and does not transmit any data about you or your device to us or to any third-party analytics or advertising service.
Data stored on your device #
The app stores three small preference values locally using your device’s standard storage:
| Preference | What it stores |
|---|---|
| Default mode | Whether you last used “wake at” or “sleep at” mode |
| Sleep onset | Your preferred sleep onset latency (5–45 minutes) |
| Premium status | Whether you have purchased the Alarm Unlock feature |
These values never leave your device and are deleted when you uninstall the app.
In-app purchases #
ProSleep offers a one-time purchase (“Premium”, $4.99) processed entirely through the Apple App Store or Google Play. We never see or handle your payment information. Purchase records are managed by Apple or Google under their respective privacy policies.
Permissions #
| Permission | Why |
|---|---|
| SET_ALARM (Android) | Lets the app schedule a system alarm when you tap “Set Alarm” |
The iOS version does not request any special permissions — it deep-links to your device’s built-in Clock app instead.
Third-party services #
ProSleep uses Google Fonts to display text. When the app first loads, it may download font files from Google’s servers. Google’s privacy policy governs those requests. Font files are cached locally after the initial download.
ProSleep does not use:
- Analytics (no Firebase, Mixpanel, Amplitude, etc.)
- Crash reporting
- Advertising networks
- Social login or account systems
Children’s privacy #
ProSleep does not knowingly collect any information from anyone, including children under 13. The app contains no features that collect, store, or transmit personal data.
Changes to this policy #
If we update this policy, we will revise the effective date above. Because we collect no personal data, material changes are unlikely.
