LightAnalyLux
Privacy Policy
Effective date: August 18, 2026
1. Overview
LightAnalyLux is an offline ambient-light measurement app. This Privacy Policy explains how the app handles information when you use its light meter, measurement history, and appearance settings.
LightAnalyLux is designed to operate on your device. It does not provide accounts, sign-in, cloud synchronization, advertising, analytics, or social features.
2. Permissions and Device Sensors
LightAnalyLux does not declare or request Android permissions. In particular, it does not request access to your location, camera, microphone, contacts, storage, or network connection.
When you start a measurement, the app reads the device's ambient light sensor, if available. The sensor provides light intensity values in Lux. LightAnalyLux uses these values only to display the current reading, create the on-device chart, and calculate the minimum, average, maximum, and light-level distribution for a measurement session.
3. Local Information and Your Controls
When you stop a measurement, LightAnalyLux stores the completed session locally in its on-device database. A saved session may include its date and time, duration, Lux readings over time, minimum, average, and maximum Lux values, and light-level distribution. The app also stores your selected light or dark appearance setting locally.
This information remains on your device. You can delete one saved measurement or delete all saved measurements from the History tab. Changing the app theme does not create a user profile or account.
4. No Transmission, Third Parties, or Tracking
LightAnalyLux does not transmit sensor readings, measurement history, device identifiers, or personal information to us or to third parties. The app has no internet permission and no runtime network feature.
The current app version does not include third-party advertising, analytics, crash-reporting, authentication, or cloud-storage services. It does not use WebView content or externally loaded resources.
5. Children and Age Requirements
LightAnalyLux is not for children under 13 years of age. A person under 13 must not download, access, or use the app. We do not knowingly collect personal information from children under 13, and the app is not intended or designed for their use.
If you are 13 years of age or older but are still a minor under the laws that apply to you, use LightAnalyLux only with the knowledge and consent of your parent or legal guardian. Parents and guardians should supervise a minor's use of the app and decide whether it is appropriate.
If you believe a child under 13 has used the app, please contact us at the address below. Because measurement records are stored locally, a parent or guardian can also remove them directly from the app's History tab or by uninstalling the app from the device.
6. Security
Measurement records are stored on the device rather than sent to a server. The app's ability to protect locally stored information also depends on the security controls of your device, including screen-lock and operating-system protections. Please keep your device secured.
7. Changes to This Policy
We may update this Privacy Policy if the app's features or information practices change. The updated version will show a revised effective date on this page. Please review this policy when you use a new version of LightAnalyLux.
