Privacy policy
Effective 15 November 2026
Honest Level is a free spirit level, inclinometer and protractor app for Android. It has no ads and no tracking, and it collects no personal data.
What the app does not do
- It does not collect, store or send any personal data.
- It has no internet access: the app does not request the Android internet permission, so it cannot send anything anywhere.
- It contains no analytics, advertising or tracking code, and no third-party SDKs that collect data.
- It requests no special Android permissions such as location, camera, microphone or contacts.
What stays on your phone
- Motion sensors. The app reads the phone's accelerometer and gyroscope to show angles. These readings are processed on the phone, while the app is open, and are not stored.
- Settings and calibration. Your choices (units, theme, alerts, auto-hold) and calibration values are saved in the app's private storage on your phone. They are deleted when you uninstall the app or clear its data.
- Sensor recordings. A hidden diagnostic screen can record raw sensor readings to a file on your phone. Nothing is recorded unless you start it, and the file only leaves your phone if you choose to share it yourself.
Feedback by email
The "Send feedback" item opens your own email app with a message to feedback@honestlevel.app, pre-filled with the app's name and version. You decide whether to send it. If you do, we receive your email address and whatever you write, and use them only to read and reply to your feedback. We do not share them with anyone or use them for marketing. You can ask us to delete your messages at any time by writing to the same address.
Children
The app is suitable for all ages and collects no data from anyone, including children.
Changes
If this policy changes, the new version will be published on this page with a new effective date.
