Privacy Policy
This privacy policy applies to the Lumora: Edge Lighting app for mobile devices (the "Application"), made by Packet Bracket. Packet Bracket is called the "Service Provider" below.
Information Collection and Use
The Application does not need an account. It does not collect or send your name, email address, phone number, contacts or location to the Service Provider. The Service Provider runs no server for the Application.
The Application does not ask for internet access. It cannot send any data off your device. It shows no advertisements, contains no analytics or crash-reporting tools, and has no in-app purchases.
The Application processes the following information only on your device:
- Notification events: when you give notification access, the Application learns which app posted a new notification. It uses this only to show the edge light in that app's color and to follow the rules you set. It does not
 read the title, text, images or any other content of your notifications, and it never stores or sends that content.
- Battery information: the battery level and whether a charger is connected. This is used to show the charging edge light and to switch to battery-saver mode when the battery is low.
- Screen shape: the size, corner shape and camera cutout of your screen, so the light fits your display.
The following information is stored only in the Application's private storage on your device and is never sent to the Service Provider:
- Preferences: your colors, themes, effects, speed, thickness, rules, battery-saver and wallpaper settings.
- App list: the package names of apps that have posted notifications, so you can pick a color for each app or turn the light off for it.
- Wallpaper photo: if you choose your own photo as the live wallpaper background, a copy of that one photo is kept so the wallpaper keeps working. It is deleted when you choose another background or uninstall the Application.
Device features and permissions
The Application uses these device features only for its core functions:
- Notification access: to know which app posted a notification so the edge light can flash. Only the app's identity is used, never the notification content. You can turn this off at any time in your device settings.
- Display over other apps: to draw the edge light around the edges of your screen. The Application does not read, record or interact with the content of other apps.
- Lock screen light: to show the edge light on a black screen when your phone is locked or the screen is off.
- Foreground service and notifications: while the charging light is on, Android requires a small visible notification. The Application may also post one test notification when you tap "Test".
- Battery optimisation exemption: asked for only through Android's own system dialog when you tap "Fix" in Setup Doctor, so the light keeps working in the background. The Application still works if you decline.
- Photos: only when you choose "Own photo" for the live wallpaper, the Application reads the single picture you pick in the system Photo Picker. It does not browse your photo library and needs no storage permission.
- Live wallpaper and Quick Settings tiles: optional features that you turn on yourself.
The Application does not use the internet, camera, microphone, location, contacts, call log, SMS or Bluetooth.
Cookies and tracking technologies
The Application does not use cookies, advertising IDs, tracking pixels, analytics or any third-party SDK that collects data.
Third Party Access
No data leaves your device through the Application, and nothing is shared with the Service Provider or with any third party.
The Application relies on Android Backup only when backups are turned on on your device. In that case, Android may include the Application's preferences in the encrypted backup stored in your own Google account, under Google's
privacy policy. The Service Provider cannot access that backup.
The Service Provider may disclose information you send to them directly, such as an email:
- as required by law, for example to comply with a subpoena or similar legal process;
- when they believe in good faith that disclosure is needed to protect their rights, protect your safety or the safety of others, investigate fraud, or respond to a government request.
Your Rights
Because the Service Provider does not receive your preferences, app list or wallpaper photo, only you can view or delete them, on your device. You can do this by clearing the Application's data or uninstalling it. For any
question, or to request deletion of an email you sent, contact packetbracket@gmail.com.
Your California privacy rights (CCPA/CPRA)
If you live in California, you have the right to know, the right to delete, the right to opt out of the sale or sharing of personal information, and the right to non-discrimination. The Service Provider does not collect, sell
or share personal information. For any request, contact packetbracket@gmail.com.
Opt-Out Rights
You can stop all processing by uninstalling the Application. This deletes all data it stored on your device. At any time, you can also turn off notification access, "Display over other apps", notifications or the battery
optimisation exemption in your device settings. The edge light will then stop working, but the Application's other screens will keep working.
Data Retention Policy
- Preferences, app list and wallpaper photo stay on your device only while the Application is installed, or until you clear the Application's data. The Service Provider never holds a copy.
- Emails you send to the Service Provider are kept only as long as needed to reply to you, or as required by law.
Children
The Application is not directed at children under 13, or a higher age where the law requires it (for example 16 in some countries). The Application collects no personal information from anyone, including children. If you are a
parent or guardian and believe your child has sent the Service Provider personal information by email, contact packetbracket@gmail.com and it will be deleted.
Security
All data the Application keeps stays in its private storage on your device. It is protected by your device's own security, such as your screen lock and device encryption. Because the Application has no internet access, this
data cannot be sent anywhere by the Application.
Changes
The Service Provider may update this Privacy Policy from time to time and will post the updated version with a new effective date. Earlier versions are available on request at packetbracket@gmail.com.
This privacy policy is effective as of 2026-10-21.
Your Consent
By using the Application and turning on its features, such as notification access or "Display over other apps", you agree to the processing described in this policy, all of which happens on your device. You can withdraw your
consent at any time by turning off those features or uninstalling the Application.
