The Polyphonic Interlace app collects nothing about you. There are no accounts, no analytics, no advertising, no tracking, and no third-party SDKs of any kind.

Nothing. There is no sign-up and no profile. The app keeps no usage logs, sends no crash reports, and transmits nothing about what you listen to or when.

Because none of it is gathered in the first place, there is nothing stored, nothing shared, nothing sold, and nothing to request or delete.

Both recordings are bundled inside the app. Pressing Play reads them from your own device. The app does not stream, download or upload audio, and it never uses your microphone.

The app makes no network requests. The Android version is not granted internet permission at all, so it is unable to make them.

The app links to raquelacevedoklein.com, khaledjean.com, brianellissound.com and Instagram. Tapping one opens your browser and hands you over to that site, which has its own privacy policy. The app is not told whether you followed a link.

On Android the app asks to post a notification. That is used for one thing: the playback controls shown while the music keeps playing in the background. On iOS, background playback needs no permission at all.

Neither platform's version asks for your location, contacts, photos, microphone or camera.

The app is rated 4+ and is safe for all ages. As nothing is collected from anyone, nothing is collected from children either.

Any change to this policy will be posted on this page.
