Privacy Policy
Last updated: October 11, 2026
This policy explains how EpDelegate (“we”, “us”) handles information when you use Reverse Audio: Reverse Singing (the “App”) on Android.
At a glance
- No account, no sign-in and no ads.
- The microphone is used only while you record. Your recordings stay on your device.
- We use Google Firebase to see how the App is used and to fix crashes. This never includes your recordings, name, email or contacts.
- We don’t sell your information or use it for advertising.
Microphone and recordings
The App records audio only after you tap the record button and you have allowed microphone access. Recordings, their names and your playback settings are saved only in the App’s storage on your device. We never receive them. They are removed when you delete them in the App, clear the App’s data or uninstall it. If you share a recording, it goes to the app you choose in Android’s share menu, and that app handles it.
Information we collect
- Usage information (Firebase Analytics): how you use the App, such as starting and finishing a recording and its length, playing, sharing, renaming or deleting a take, changing settings and your microphone permission choice; plus app version, device model, Android version, language, approximate region (from your IP address) and an app instance identifier. Collection of the Advertising ID is turned off.
- Crash reports (Firebase Crashlytics): if the App crashes or hits an error, technical details such as the error, device model, Android version, app version and the screen that was open.
- App settings (Firebase Remote Config): the App downloads a few settings, such as this page’s link and whether an update is required. Google receives your IP address and a Firebase installation identifier to deliver them.
We don’t collect your name, email, phone number, contacts, photos, precise location or payment information.
How we use it
To understand which features are useful, to find and fix bugs and crashes, and to keep the App working, for example by asking you to update a version that no longer works properly.
Sharing and retention
We don’t sell, rent or share your information for advertising. The data above is processed for us by Google under its own terms (Firebase privacy, Google Privacy Policy), possibly on servers outside your country. Usage data is kept for at most 14 months and crash reports for about 90 days. We may disclose information if required by law.
Your choices
You can turn off microphone access in Android settings, delete recordings in the App, and stop all collection by uninstalling the App. Depending on where you live, you may have rights to access or delete your personal information; contact us and we’ll help where we can.
Children
The App is meant for a general audience and is not directed at children under 13. We don’t knowingly collect personal information from children.
Changes
We may update this policy from time to time and will change the “Last updated” date above when we do.
