Decibel Labs built RewindX ("Reverse Video - RewindX") as a video editing app. This Privacy Policy explains what information the app processes, what third-party services may collect, and what choices you have.
Local video processing
RewindX lets you select videos, trim them, reverse video playback, reverse audio, save exported files, and share results. The video files you choose are processed on your device. We do not upload your selected videos to our own servers.
Exported videos are saved to your device storage or media gallery when you choose to save them. If you share a result using another app, that app handles the shared file under its own privacy policy.
Information the app may access
Depending on your Android version and the actions you take, the app may request access to videos or media files you select, storage or media permissions, and notifications.
The app uses this access only to provide the editing, saving, sharing, and progress features you request.
Advertising
We may use Google AdMob to show ads in the app. AdMob and Google Mobile Ads services may collect and use information such as device identifiers, advertising identifiers, app interaction information, approximate location derived from network information, and diagnostic information to deliver ads, measure ad performance, prevent fraud, and comply with legal obligations.
Ads may be personalized or non-personalized depending on your region, consent choices, device settings, and Google settings. Where required, the app may show a consent form or privacy options form before requesting ads or to let you update your choices.
You can learn more about how Google uses information from apps that use its services at https://policies.google.com/technologies/partner-sites.
You can manage Google ad personalization at https://adssettings.google.com.
Crash reporting
We may use Firebase Crashlytics to understand and fix crashes and stability issues. Crashlytics may automatically collect crash stack traces, relevant app state at the time of a crash, relevant device metadata, and a Crashlytics installation identifier. This information helps us diagnose crashes, prioritize fixes, and improve app reliability.
Crash reports do not include your selected video files.
Analytics
We may use Google Analytics for Firebase to understand app usage patterns, screen views, feature engagement, and product performance. Analytics may collect app instance identifiers, device and app information, and app interaction events. We use this information to improve features, reliability, and the overall app experience.
Data sharing
We do not sell your selected videos or personal information. Information may be processed by Google services used in the app, including AdMob and Firebase Crashlytics, as described above. These providers process data under their own terms and privacy policies.
Data retention
Videos exported by the app remain on your device until you delete them. Crash and advertising data retained by Google services is handled according to Google retention practices and your available controls.
Children
RewindX is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, contact us and we will take appropriate steps.
Your choices
You can delete exported videos from your device, change or revoke ad privacy choices through Google settings or any in-app privacy options when available, reset or delete your device advertising ID in Android settings, disable app notifications in Android settings, and contact us about this policy.
Security
We use reasonable technical measures to protect the app and reduce unnecessary data collection. No method of transmission or storage is completely secure.
Changes to this policy
We may update this Privacy Policy when the app, third-party services, or legal requirements change. The updated version will show a new Last updated date.
