Oyster Studio built the Bubble Level: Angle Meter Pro app as a utility tool. This app is provided by Oyster Studio and is intended for use as is.
This page is used to inform users regarding our policies with the collection, use and disclosure of personal information for anyone using this app.
By installing and using this app, you agree to the collection and use of information in relation to this policy. We only collect and use information as described in this Privacy Policy.
1. Information We Do NOT Collect
• We do not require you to create an account or log in.
• We do not ask for your name, address, phone number or other personal identity information.
• We do not collect your photos, files, or contacts.
• We do not track your precise GPS location.
2. Information We May Collect
The app itself is designed to work mostly offline and on‑device. However, some limited, non‑personal information may be collected automatically for analytics, debugging, or app improvement, such as:
• Device information (e.g., device model, operating system version)
• App information (e.g., app version, screens visited, basic usage statistics)
• Crash logs and performance data (e.g., error reports if the app crashes)
This information is typically aggregated and does not identify you personally. It is used only to improve stability, performance and user experience.
3. Sensors and Permissions
Bubble Level: Angle Meter Pro uses built‑in sensors of your device to provide its features, such as:
• Accelerometer and/or gyroscope – for bubble level and angle measurements
• Magnetometer – for compass functionality (if available)
• Light sensor – for lux (light) meter (if available)
• Vibration (VIBRATE permission) – to provide haptic feedback when you reach a level or perform certain actions
All sensor readings are processed locally on your device. We do not store or transmit sensor data to our servers.
4. Local Storage (Settings & Preferences)
The app may store certain settings and preferences only on your device, for example:
• Language preference
• Dark mode / theme settings
• Calibration values
• Other app configuration options
This data is saved locally on your phone using standard Android storage mechanisms (such as shared preferences) and is not shared with us.
5. Third‑Party Services
The app may use third‑party services to help us improve quality, stability, or to show in‑app prompts (like rating the app). Examples of such services may include, but are not limited to:
• Google Play services (e.g., in‑app review prompts, basic analytics)
These third‑party services may collect information used to identify your device in a limited, technical way (e.g., device ID, crash logs, usage data). Each third‑party service has its own privacy policy. You are encouraged to review their policies for more information on how they handle data.
6. Children’s Privacy
This app is not targeted directly at children. We do not knowingly collect personal information from children under the age of 13 (or the minimum legal age in your region).
If you believe that a child has provided us with personal information, please contact us at alirazaayubkhan@gmail.com, and we will take steps to delete such information.
7. Data Security
We take reasonable steps to protect any information that may be processed through the app. However, please remember that no method of transmission over the internet, or method of electronic storage, is 100% secure.
Since we store most settings only locally on your device and do not collect sensitive personal information, the risk is minimized.
8. Changes to This Privacy Policy
We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes.
We will notify you of any changes by posting the new Privacy Policy on this page and/or updating the “Last updated” date at the top.
Changes are effective immediately after they are posted on this page.
