Last Updated: July 2, 2026
1. Introduction
This Privacy Policy explains how information is collected, used, disclosed, stored, and protected when you use LED Banner - Big Text Maker. The App is a mobile utility application distributed for Android through Google Play.
Unless expressly stated inside the App, the App does not require users to create an in-app account. By using the App, you acknowledge that you have read and understood this Privacy Policy.
2. Data Processing Summary
- The App is designed to create LED scrolling text, neon messages, flashing visual effects, teleprompter-style text, GIF exports, and video exports.
- LED text, danmaku history, teleprompter content, saved templates, selected images, selected audio, and export files are primarily processed on your device.
- The reviewed code did not identify advertising SDKs, analytics SDKs, crash reporting SDKs, third-party login SDKs, payment SDKs, or subscription SDKs.
- When you submit feedback, the App may send support content and limited device or network information to the business support server.
- The App may request permissions for media, files, microphone, vibration, network access, storage on older Android versions, and device flashlight features when needed for specific features.
3. Information You Provide
You may provide information when you contact support or submit feedback, including your email address, feedback title, feedback message, screenshots, logs, files, or other details you choose to include.
4. Local App Data
The App may store the following data locally on your device:
- LED messages, danmaku history, teleprompter text, saved templates, presets, colors, speed settings, and layout settings.
- User-selected background images, local audio files, audio title, duration, local file path, and a file hash used for local identification or de-duplication.
- Exported GIF or video files, temporary media files, and system gallery items when you choose to save exports.
- Preferences such as language, theme color, keep-screen-on setting, and cached legal documents.
Unless you choose to share, export, or submit content through a support channel, the reviewed code did not identify active upload of this local creative content.
5. Feedback, Device, and Network Information
When you submit feedback, the App may process:
- feedback email address, title, and content;
- a random device-level user identifier generated by the App;
- device model, operating system version, screen size, system language, App language, network type, App version, package name, and platform information;
- IP address or public IP information used in support request headers.
Feedback is transmitted over HTTPS and may be encrypted in the request body. This information is used to respond to support requests, troubleshoot issues, maintain the App, and improve reliability.
6. Device Permissions
The App may request permissions only when needed for a feature:
- Network access: used for feedback submission, legal document loading, IP lookup, opening web links, and Google Play links.
- Microphone: used for real-time volume or spectrum-driven flashing and waveform effects. The reviewed code did not identify saving or uploading raw microphone recordings.
- Photos, media, and files: used to select background images or audio files, process user-selected media, and save exported GIF or video files.
- Storage on Android 10 and below: used to save exported media to the system gallery.
- Vibration: used for local warning-light feedback.
- Flashlight hardware: used for torch, warning light, Morse light, and music-flash effects. The reviewed Android manifest declares camera and flash hardware features but did not identify camera photo or video capture permission.
- Audio settings: may support audio playback or audio effect behavior where available.
You can manage permissions in your device settings. Some features may not work if required permissions are disabled.
7. Third-Party Services and External Links
The reviewed materials identify the following external services or platform links:
- Google Play Store: app distribution, store page, rating flow, and download links.
- Business support server at
tomata.mobiaura.com: feedback submission and related support request handling. - ipify at
api.ipify.org: public IP lookup used in connection with feedback headers. - System share sheet: sharing is controlled by the destination app selected by you.
- Android system file picker, media store, and gallery: user-selected file access and media saving.
- Legal document web pages or WebView loading: used to display policy pages where configured.
Third-party websites, app stores, and share targets are governed by their own terms and privacy policies.
8. How Information Is Used
Information may be used to:
- provide LED, neon, flashing, audio-reactive, preset, export, and gallery-saving features;
- remember local settings and user-created templates;
- provide support and respond to feedback;
- troubleshoot bugs, compatibility issues, permission issues, and export failures;
- maintain security, reliability, and abuse prevention for support requests;
- comply with applicable legal obligations and platform rules.
9. Sharing of Information
We do not sell personal information for money. We may share information only when needed for support providers, app marketplaces, external services listed above, legal obligations, safety, security, business transfers, or when you direct us to share content through export or system sharing features.
10. Data Retention
Local app data remains on your device until you delete it in the App where supported, clear App data, or uninstall the App. Temporary export or audio cache files may remain according to App logic and operating system cache behavior. Support emails and feedback records may be retained for the period reasonably necessary to respond to your request, maintain service records, resolve disputes, comply with law, and protect the service.
11. Your Choices and Controls
You may manage permissions in Android settings, delete local content where the App provides deletion controls, clear App data, uninstall the App, choose whether to submit feedback, and contact support to request access, correction, or deletion of feedback records where applicable.
Because the App does not require an in-app account, we may need information sufficient to locate relevant support records, such as the email address used for feedback, request date, device platform, or App-generated identifier if available.
12. Regional Privacy Rights
Depending on your location, you may have rights to access, correct, delete, restrict, object to processing, withdraw consent, request portability, appeal certain decisions, or complain to a data protection authority. These rights may vary by region, including the EEA, United Kingdom, Switzerland, United States, Canada, Australia, New Zealand, Japan, South Korea, Singapore, Brazil, India, Thailand, Hong Kong, Taiwan, and other regions.
13. Children's Privacy
The App is intended for a general audience and is not directed to children under 13, under 16, or the minimum age required by applicable local law. We do not knowingly collect personal information from children without appropriate consent. If you believe a child has provided personal information through feedback or another support channel, please contact us.
14. No User Account by Default
The App does not require users to create an in-app account by default. Local data is stored on the device. There is no reviewed account deletion flow because no in-app account system was identified.
15. Security
Reasonable technical, administrative, and organizational measures are used to protect information. However, no transmission or storage method is completely secure. You are responsible for keeping your device, operating system, app store account, and backups secure.
16. Changes to This Privacy Policy
This Privacy Policy may be updated from time to time. The latest version will be made available in the App, on the website, or through other appropriate channels. The Last Updated date shows when this Privacy Policy was last revised.
