Privacy Policy
App: Flag Waver Maker
Last updated: September 9, 2026
YOULAB ("we", "us", or "our") provides the Android app Flag Waver Maker (the "App"). This Privacy Policy explains how information is handled when you use the App.
1. Information stored by the App
To provide its features, the App stores the following information on your device:
- Custom LED dot patterns, animation frames, playback settings, sign text, layout, and display settings.
- App preferences such as language settings.
- GIF or MP4 files temporarily created in the App cache for the share feature.
This information is stored locally on your device. We do not operate our own server to receive or store this information.
2. Advertising
The free version may display ads using the Google Mobile Ads SDK (AdMob). Google may process device information, advertising identifiers, ad interaction data, and diagnostic information for ad delivery, measurement, and fraud prevention. Where consent is required, choices are presented through Google's consent management tools. Please review Google's policies for information about Google's handling of data.
3. Crash diagnostics
To improve stability and investigate defects, the App uses Google Firebase Crashlytics. Crashlytics may collect stack traces for crashes and non-fatal errors, relevant app state, technical device metadata, and Crashlytics or Firebase installation identifiers.
We do not set custom Crashlytics logs or custom keys to custom patterns, sign text, shared files, or other content created by users. Technical exception messages may contain information about the operation that failed. These diagnostic data are processed by Google LLC and Firebase.
4. In-app purchases
Premium upgrades and purchase restoration use Google Play Billing. Payment information is processed by Google Play. We do not receive or store your credit card number or other payment information.
5. Sharing
Only when you choose to use the share feature, a GIF or MP4 file temporarily created for sharing and share text are provided to the external app or service that you select. The shared file is not saved to your photo or video storage; it is automatically removed from the App cache after a short period that allows the receiving app to read it. Please review the privacy practices of those external services.
6. Security
We do not send settings or creative data stored by the App to our own servers. They are managed on your device. Information related to advertising, purchases, and crash diagnostics is handled by the applicable Google services and Firebase under their security measures.
7. Retention and deletion
Preferences and custom patterns stored on your device remain until you clear the App's data or uninstall the App. Temporary GIF or MP4 files for sharing are automatically removed from the App cache.
8. Children
The App does not knowingly limit use by people for whom parental consent may be required. Parents or guardians should review device and Google Account settings as appropriate.
9. Changes to this Privacy Policy
We may update this Privacy Policy when necessary. Changes take effect when the updated policy is posted on this page.
