USE CASES / LUNEVON

Practical uses

These are examples of how to use the available on-device readings, not calibrated measurements or a substitute for professional testing.

Compare light levels

Take readings near a window and further inside a room under comparable conditions.

Find a work spot

Compare relative light levels on a desk and elsewhere in the room.

Review changes

Save measurement sessions and compare them after adjusting the lighting.

Light as measurable data

Lunevon Light reads the Android ambient light sensor (TYPE_LIGHT) and shows the current light level in lux. Readings depend on the sensor and measurement conditions.

The LIVE screen includes current, average and peak values, a dynamic 60-second trace and a light-field visualization driven by actual sensor data.

01 / LIVE

Live ambient light

Live lux reading, reactive light-field visualization, statistics and a 60-second trace.

01 / SESSIONS

Measurement sessions

Choose a 10-, 30- or 60-second measurement. Each session is saved locally with a name, timestamp, statistics and trace. Stable sensors are represented using available real samples rather than fabricated data.

02 / COMPARISONS

Compare two measurements

Compare the averages of two saved sessions. Lunevon Light displays differences in lux and percent; comparisons can be stored independently of their source sessions.

03 / DATA QUALITY

Understanding accuracy

Readings depend on the hardware sensor, sensor placement, obstruction and Android implementation. Lunevon Light is not a replacement for a calibrated lux meter. Devices without a light sensor cannot provide measurements.

Lunevon Light • 1.0.1 • Updated 11 October 2026

Ambient light sensor data

Lunevon Light reads the built-in Android Sensor.TYPE_LIGHT readings (lux), measurement timestamps and available sensor information. These are used to show current readings, charts, average, minimum and maximum values. The app does not request location, camera, microphone, contacts or messages permissions.

Local processing

Readings and calculations are processed on the device. The reviewed 1.0.1 source has no INTERNET permission, server synchronisation, user accounts, advertising, analytics SDKs or automatic transmission of measurements to the developer. Ambient light observation runs while the app is open; active measurements are interrupted on leaving the foreground.

Sessions, comparisons and deletion

Saved sessions and comparisons, including user labels, times, durations, readings and statistics, are kept locally. You can delete individual records in the app and remove all local app data using Android Settings or by uninstalling. The source configuration disables ordinary Android backup and app-data transfer.

Permissions

Sensor.TYPE_LIGHT does not need a separate Android permission. POST_NOTIFICATIONS is used only for an optional user-enabled quick-access notification. The normal system permission RECEIVE_BOOT_COMPLETED may restore an already enabled notification after a device reboot, but does not initiate background light measurements.

Website and enquiries

The LUNEVON website opens only when you choose to open it. Tapping an email address copies it to the clipboard; no message is sent automatically. Visiting the website is covered by the separate website privacy policy. If you email support yourself, your sender address and message are processed to respond. Sensor readings are not transmitted as part of these actions.

Sensitive permission

POST_NOTIFICATIONSThis permission is used for an optional quick-access notification that you can enable or disable in Settings. It does not enable background ambient light measurements. Denying the permission does not limit Lunevon Light core functionality.
