Privacy policy

Last updated 14 September 2026

Serotone is a music player for files you already own. It does not collect, store or share personal data. This page explains what the app does with your information, which is very little.

What we collect

Nothing. Serotone has no accounts, no analytics, no advertising and no servers of its own. We never receive your name, email, location, device identifiers, listening history or any of your files.

What stays on your device

• Music files you import are copied into the app's private storage on your device. They are never uploaded anywhere.
• Cover art, lyrics and metadata you add or edit are stored alongside your library on the device.
• Remix settings and app preferences are saved in a local settings file on the device.
• 8D renders and analysis data are cached locally so effects load faster.

Deleting the app deletes all of this. There is no copy anywhere else.

Permissions

• Photo library is used only when you choose an image as cover art. The app reads the image you pick and nothing else.
• Local network is used only by Wi-Fi transfer, which starts a small web server on your phone so you can send files from another device on the same network. It runs only while that screen is open and is reachable only from your local network.
• Background audio lets playback continue when the screen is locked.

Purchases

Serotone Pro is a one-time purchase handled entirely by Apple through the App Store. We do not receive your payment details or any personal information about you. Apple's own privacy policy governs the transaction. The app stores a local flag that Pro is unlocked, and "Restore purchase" asks Apple to confirm it.

Files you open from other apps

When you share or open an audio file into Serotone from Files, AirDrop or another app, the file is copied into the app's storage. Nothing about the source is recorded or sent anywhere.

Children

Serotone does not knowingly collect information from anyone, including children, because it collects no information at all.

Changes

If a future version adds anything that touches your data, such as crash reporting, this policy will be updated before that version ships, and the date at the top will change.
