Privacy Policy — Bubble Level Pro

Last updated: September 18, 2026

Bubble Level Pro was designed to work locally on the user's device. CEWIA Tech does not require an account, does not display ads, and does not collect or send the user's measurements to CEWIA Tech servers.

1. About this policy

This Privacy Policy explains how Bubble Level Pro, developed by CEWIA Tech, uses device resources to provide level, tilt, surface, and angle measurements.

2. Device sensors

To perform measurements, Bubble Level Pro uses motion and orientation sensors available on the device, such as the accelerometer, gravity sensor, gyroscope and/or rotation sensor, depending on the availability and characteristics of the device.

Sensor readings are processed locally to calculate and display measurements. CEWIA Tech does not receive sensor readings or measurements made by the user. Sensor availability and accuracy may vary depending on the device.

3. Information collected

Bubble Level Pro does not require registration or login with CEWIA Tech and was not designed to collect the user's personal data. The app does not collect the user's name, address, email address, phone number, or location through CEWIA Tech services.

4. Permissions and resources not used

The current version of Bubble Level Pro does not need access to location, camera, microphone, or contacts to perform its main functions and does not require an internet connection to take measurements.

5. Settings and calibration

App preferences, settings, and information required for calibration may be stored locally on the device in order to preserve the user's choices and enable the features to work properly.

This local information is not used by CEWIA Tech for user profiling, advertising, or tracking.

6. Processing and storage

The main functions of Bubble Level Pro are performed locally on the device. The app does not use a CEWIA Tech account or a CEWIA cloud service to store measurements.

7. Data sharing and sale

CEWIA Tech does not sell users' personal data. Bubble Level Pro was not designed to share measurements or personal information with advertisers, advertising networks, or data brokers.

8. Advertising and usage analytics

The current version of Bubble Level Pro does not display ads and does not use CEWIA Tech tools to create advertising profiles or individually track app usage.

9. Security

CEWIA Tech seeks to limit the app to the resources required for its operation and prioritizes local processing. However, no system can guarantee absolute security.

10. Children

Bubble Level Pro is not specifically directed at children and does not include features intended for the intentional collection of children's personal data by CEWIA Tech.

11. Changes to this policy

This Privacy Policy may be updated to reflect changes to the app, legal requirements, or platform policies. The date of the latest update will be shown at the beginning of this page.
