Bubble Level

Privacy Policy — English

In short: TANZI AI SYSTEMS does not require an account and does not store your measurements. Device motion readings are processed on your device. The app includes Google Mobile Ads, which may collect and share limited device and usage data as described below.

1. App and developer

Bubble Level is provided by TANZI AI SYSTEMS. Questions about this policy may be sent to [email protected].

2. Information handled by the app

• Motion sensor data: accelerometer readings are used only to calculate the device angle and bubble position. They are processed locally and are not stored or sent to TANZI AI SYSTEMS.
• Local preferences: the app may store non-personal settings on the device, such as first-launch or display state.
• No account data: the app does not ask for a name, phone number, account, contacts, photos, microphone, camera, or precise location.

3. Advertising and third-party data

The app uses the Google Mobile Ads SDK (AdMob) to load and measure advertisements. Depending on device settings, consent choices, region, and Google services, the SDK may automatically collect or share:

• IP address, which may be used to estimate general location;
• app interactions such as launches, taps, and ad views;
• diagnostic and performance information, such as launch time, crashes or hangs, and energy usage;
• device or other identifiers, including the Android advertising ID and app set ID where available.

This processing is used for advertising, analytics, security, and fraud prevention. Data collected by the Google Mobile Ads SDK is transmitted using encryption in transit. Google acts under its own policies. Learn more at Google Privacy Policy and How AdMob uses information.

4. Permissions

The app uses the accelerometer for its core level function, vibration for level feedback, and internet/network access to request ads. It does not request access to contacts, files, camera, microphone, or precise GPS location.

5. Children

Bubble Level is not specifically designed or directed to children under 13. TANZI AI SYSTEMS does not knowingly collect personal information directly from children through the app.

6. Retention, control, and deletion

TANZI AI SYSTEMS does not operate user accounts or retain personal measurements on its servers, so there is no account record to delete. Users can clear local app data or uninstall the app at any time. Advertising identifiers can be reset or deleted through Android privacy settings. Questions or privacy requests can be sent to the email above.

7. Security and changes

We use reasonable safeguards and limit app permissions to its stated functions. No transmission or storage system can be guaranteed completely secure. This policy may be updated when the app, SDKs, or legal requirements change. The effective date at the top identifies the latest version.
