Bubble Level Privacy Policy
Last Updated: October 14, 2025
This Privacy Policy explains how Bubble Level (“the App”) handles user information. By installing or using the App, you agree to this Policy.
1. Information We Collect
Direct Input Information: The App does not provide sign-up, account creation, or name/email submission features and does not collect any personally identifiable information directly from users.
Device Sensor Data: The App uses the device’s accelerometer data to calculate the level (tilt) state. This data is processed only in real time and is never transmitted outside the App.
Local Storage Information: The following values are stored locally on the device via `AsyncStorage`:
Calibration values (`calibrationX`, `calibrationY`)
Ad display preference (`showAds`) These values are non-identifiable and used solely to maintain App functionality.
Third-Party Advertising Data: Ads may be served through Google AdMob SDK (`react-native-google-mobile-ads`). During this process, Google may automatically collect advertising identifiers, device information, IP addresses, and ad interaction data. The App developer does not access or retain this data.
2. Purpose of Data Processing
Device Sensor Data: To calculate tilt and provide bubble-level and calibration functions.
Local Storage Data: To retain user calibration and ad display preferences between sessions.
Advertising Data: To deliver and analyze ad performance through Google AdMob.
3. Data Retention and Deletion
Sensor Data: Processed in real time and immediately discarded.
Local Storage Data: Retained locally until the user resets calibration (“Reset Calibration”) or uninstalls the App.
Advertising Data: Managed by Google according to its own retention policies. See:
4. Third-Party Sharing and External Modules
Recipient: Google LLC (Google AdMob)
Data Shared: Advertising ID, device info, IP address, and ad interaction details necessary for ad delivery
Purpose: Personalized/non-personalized ad delivery, ad performance measurement, and fraud prevention
Retention: Governed by Google’s policies; the App developer cannot access this data. No personal information is sold or shared with other third parties.
5. User Rights and Controls
Device Permission Control: Users can manage sensor access and ad personalization through their device settings.
Delete Local Data: Press “Reset Calibration” in the App or uninstall the App to remove calibration and ad settings.
Ad Personalization Control: Manage personalized ad preferences via Android/iOS ad settings or Google’s Ad Settings.
6. Data Security Measures
The App does not operate any server-side databases.
User configuration data is stored only on the device.
The App does not process sensitive personal data; locally stored values are general settings and not encrypted. Please manage device access securely.
7. Children’s Privacy
The App is not intended for children under 13. If we become aware that personal information from a child under 13 has been collected, we will delete it promptly.
8. Changes to This Policy
This Policy may be updated to reflect App feature changes or legal requirements. Updates will be posted with App releases.
Significant changes will be communicated in-App or via other appropriate methods.
