Level & Compass privacy policy
Level & Compass is a bubble level and a compass for Android. You need no account to use it. This page tells you what data the app uses, where it goes, and the choices you have.
Short version
- The level and the compass work only on your phone. Sensor readings never leave the device.
- True north (Pro, optional) reads your rough location once, on the device, to correct the compass. We do not send or keep your location.
- The free version shows one banner ad from Google AdMob. Google collects some data to show and measure ads (details below). Pro removes the ad.
- Pro is bought through Google Play. We never see your payment details.
- We, Springlab, run no servers for this app and collect no data ourselves. The app has no analytics and no crash reporting of its own.
Data the app uses on your phone
| Data | Why | Leaves the phone? |
|---|---|---|
| Motion and magnetic sensors | To show tilt, angle and heading | No |
| Approximate location (only if you turn on true north) | To work out the magnetic declination for your area. The app keeps only the result: the declination, and the strength and dip of Earth's magnetic field there (used to warn about magnets). It does not keep the location itself. | No |
| Your settings and calibration | To remember your choices | No (Android may include them in your own device backup) |
| Whether you own Pro | A copy of Google Play's answer, so Pro users never see an ad, even offline | No (see Purchases) |
Ads (free version)
The free version shows one banner, at the bottom of the Settings screen. Google AdMob provides it. Google's Mobile Ads SDK collects and shares this data, encrypted in transit, for advertising, analytics and fraud prevention:
| Data | Details |
|---|---|
| IP address | Can be used to estimate your general location |
| App interactions | For example app launches and ad taps |
| Diagnostics | App and SDK performance, such as launch time |
| Device identifiers | Android advertising ID and app set ID |
To know if it must ask for consent, the app uses Google's User Messaging Platform. It contacts Google each time the app starts (free version only). Where the law requires it (for example in the EEA, the UK and some US states), the app asks for your consent before it loads ads, and starts Google's ad SDK only when the answer allows it. You can change your choice at any time in Settings → Privacy choices. You can reset or delete your advertising ID in Android Settings. The ad SDK may also use Android's Privacy Sandbox ad features (Topics, ad measurement); you can turn these off in Android Settings, under Privacy → Ads (the exact path depends on your phone). When you open the app with Pro, it does not start the ad SDK and does not ask for ad consent. Google's use of this data is covered by How Google uses information from sites or apps that use its services and the Google Privacy Policy.
Purchases
Pro is a one-time purchase through Google Play, with no subscription. Google Play handles the payment under Google's own terms and privacy policy. The app only asks Google Play whether you own Pro, and keeps that answer on your phone. We never see your payment details, and the app sends no purchase data to us.
Children
The app is not made for children under 13 and we do not knowingly collect data from them.
Your choices
- Leave true north off, or turn off location access in Android Settings at any time.
- Change ad consent in Settings → Privacy choices (where it applies).
- Buy Pro to remove the ad. From the next start, the app no longer starts the ad SDK.
- Uninstall the app to delete everything it stored on your phone.
Changes
If this policy changes, we update this page and the date at the top.
