Perfect HIIT Last updated: February 22, 2026
Perfect HIIT is an offline interval timer app. It does not collect, store, or transmit any personal data to external servers. All workout data stays on your device.
We do not collect any personal information. The app does not require an account, does not use analytics services, and does not contain advertising.
- Workout presets and custom timers
- Workout session history and effort ratings
- App preferences (sound, haptics)
This data is stored locally using Apple's on-device frameworks and is never sent anywhere.
If you have opted in to share diagnostics with app developers through your device settings (Settings > Privacy & Security > Analytics & Improvements), Apple may collect and forward anonymized crash logs and performance data. This is handled entirely by Apple and contains no personally identifiable information. You can disable this at any time in your device settings.
The app does not integrate any third-party analytics, advertising, or tracking services.
The companion Apple Watch app communicates directly with the iPhone app over a local Bluetooth/Wi-Fi connection using Apple's WatchConnectivity framework. No data is transmitted to any external server.
The app does not collect any data from any user, including children.
