Phone Banner Privacy Policy
This Privacy Policy explains how information is handled in Phone Banner (the "App"), a scrolling LED sign app for cheering at concerts, sports games and events. The App is developed by J.Biglion.
- We do not ask you to create an account and do not collect your name, email, or phone number.
- Your messages, presets and settings are stored in the App on your device. We do not run servers that receive them. Android backup or device transfer may include this data, depending on your device settings.
- In Group Cheer mode, phones connect directly to each other over Bluetooth and Wi-Fi. Data exchanged for the cheer stays between the connected nearby devices and is not sent to us.
- The sound reaction feature uses the microphone only to measure loudness while you have it turned on. Sound is not recorded, saved or sent.
- The App shows ads through Google AdMob on some screens. No ads are shown on the full-screen playback screen.
1. Information stored on your device
The following data is created by you and saved in the App's storage on your device. It is not sent to us and we cannot access it. It stays on your device until you delete it in the App or uninstall the App.
| Data | Purpose |
|---|---|
| Saved presets (message, colors, speed, effects, LED settings) | Let you replay your banners |
| Recent messages, favorites, auto-saved drafts | Quick replay and restoring unsaved edits |
| App settings (brightness, language, default values, mirror mode, etc.) | Remember your preferences |
Android backup and device transfer: The App allows Android system backup. Depending on your device and account settings, saved banners, recent messages and settings may be included in a cloud backup or transferred to a new device. These backups are managed by the operating system or device provider, not by the developer. Uninstalling the App does not necessarily delete existing backups; manage them in your device or backup account settings. See Android Auto Backup.
2. Permissions and device features
| Feature | Permission / Device feature | Purpose |
|---|---|---|
| Playback screen | Screen brightness, keep screen on (no permission required) | Show the banner at full brightness without the screen turning off |
| Flashlight strobe | Camera flash (torch) only. The camera is not turned on for photos or video. | Blink the flashlight for cheering |
| Light stick sound reaction | Microphone (RECORD_AUDIO) | Make the light stick react to surrounding sound. The microphone is used only while the sound reaction toggle is on and the light stick screen is open. The App only calculates loudness; sound is not recorded, saved or sent. |
| Group Cheer (nearby connection) | Android 12 and later: Nearby devices (BLUETOOTH_SCAN, BLUETOOTH_ADVERTISE, BLUETOOTH_CONNECT) Android 13 and later: Nearby Wi-Fi devices (NEARBY_WIFI_DEVICES) Android 17 and later: Local network (ACCESS_LOCAL_NETWORK) Android 12L and earlier: Location | Find nearby phones and connect them directly. On Android 12L and earlier, Android requires location permission to scan for nearby devices. The App does not use it to determine or store your location. |
| QR code join (Group Cheer) | No permission required. The App does not have camera permission; Google's code scanner in Google Play services does the scanning. | Read the QR code shown on the host's phone. The App receives only the scanned text and never receives camera images. |
You can deny or revoke any permission at any time in your device settings. Only the related feature will stop working.
3. Group Cheer (nearby device connection)
Group Cheer uses Google Nearby Connections, part of Google Play services, to connect phones directly over Bluetooth and Wi-Fi. An internet connection is not required.
- Data exchanged between connected phones: room name, device model names, the cheer message and display settings, start time and stop signal, each phone's order and screen ratio, a random ID used only to recognize a phone that reconnects, and timing information used to synchronize clocks.
- Who can see it: the room code and your device's model name may be visible to nearby devices using the App to search for rooms. The room name and cheer message are shared only with phones that join the room with the room code. The host can remove a phone from the room.
- This data is exchanged only between the connected devices and is not sent to our servers. It is not kept after the session ends, except for messages you save as presets on your own device.
- QR code join: the QR code contains only the room code.
4. Advertising (Google AdMob)
The App displays ads provided by Google AdMob on some screens, such as the home, editing, template and My Banners screens and the exit dialog. No ads are shown on the playback, light stick or Group Cheer screens. A full-screen ad may appear before the light stick screen opens. Google and its partners may collect and use the following information to serve and measure ads:
- Advertising ID (Android Advertising ID)
- IP address and approximate location derived from it
- Device information (model, OS version, language)
- Ad interaction data (impressions, clicks)
For more information, see How Google uses information from sites or apps that use its services and Google Privacy Policy.
You can reset your Advertising ID or opt out of personalized ads in your device's Settings > Google > Ads (or Settings > Privacy > Ads).
5. Users in the EEA, UK and Switzerland
If you are in the European Economic Area, the United Kingdom or Switzerland, the App asks for your consent through Google's User Messaging Platform before ads are personalized. You can change your choice at any time from Settings > Privacy options in the App.
The legal basis for ad-related processing is your consent (GDPR Art. 6(1)(a)). You have the right to access, correct, delete, restrict, or object to the processing of your data, and to lodge a complaint with your local data protection authority.
6. Data retention and sharing
We do not store personal data on our own servers. Uninstalling the App deletes its local data. Android backups may remain separately and may restore data when the App is reinstalled. Data collected by Google AdMob is retained according to Google's policies. We do not sell or share personal data with any third party other than Google as described above.
7. Children
The App is not directed at children under 13 (or the minimum age in your country). We do not knowingly collect personal information from children.
8. Changes to this policy
We may update this Privacy Policy. Changes will be posted on this page with a new effective date.
