Privacy Policy — Earhythm
Last updated: 10 September 2026
Earhythm is a music player for the audio files already stored on your device. It has no account system and requires no sign-in.
Earhythm is currently completely free: no advertising, no purchases, and every feature included. This version sends nothing anywhere. Optional online features are planned, and each will sit behind the Online Features switch in Settings, which is off until you turn it on.
What we do not do
We do not collect your name, email address, phone number, or any account information, because Earhythm has no accounts. We do not upload your music. We do not upload your listening history. We do not sell anything about you to anyone.
Your music library, your play history, your moods, playlists, and queues are read and written on your device and are never sent to us.
What Earhythm reads, and why
Audio files on your device. With your permission, Earhythm reads the music in your device's shared media storage so it can list and play it. This is what the audio access prompt is for. The files are read on your device and never leave it. No song title, artist, file name, or play count is ever transmitted.
Writing tags. When you correct a song’s details in Tagger, Earhythm writes those tags into that audio file, so the correction travels with the song. Android asks for your permission before the first such change to a file. Earhythm never moves or deletes your files, and nothing about them is sent anywhere.
Earhythm does not request access to your photos, videos, documents, contacts, calendar, location, camera, or microphone.
Advertising
The current version of Earhythm contains no advertising and no advertising SDK. The app does not hold the Android permission required to reach the internet, so it cannot send anything to an ad network — or to anyone else. If a future version introduces advertising, this policy will describe exactly what that involves before that version ships, and the date at the top will change with it.
On-device suggestions
The track editor offers a "Suggest possible moods" action. When you press it, the song's title, artist, and album — and any request you type — are handed to Android's own on-device AI (AICore, running Gemini Nano) on phones that support it. The processing happens on your device, and Earhythm sends nothing over the network. Android's AICore system component manages its own models under Google's terms, separately from this app. The action runs only when you press it — nothing is analysed in the background.
What Earhythm stores, and where
Everything Earhythm creates is kept in its own private storage on your device:
- an index of your music library, so it does not have to rescan constantly
- corrections you make to a title, artist, album, or cover art
- moods, playlists, queues, and listening history
- a diagnostic log of app events, capped at 200 entries and 128 KB
None of this is uploaded, and none of it is readable by other apps.
Your music files are not modified
Corrections you make are stored separately as an overlay. Your original audio files are left exactly as they are, so any change can be undone.
Two actions are exceptions, and both are yours to start: deleting a file, and renaming a file. In each case Android — not Earhythm — shows a confirmation dialog first, and the app cannot bypass it.
Purchases
The current version has no in-app purchases; everything is included. If a paid unlock is introduced in a future version, Google Play would handle the payment end to end — we would never see your card details, your name, or your billing address — and this policy will be updated before that version ships.
Analytics
Earhythm contains no analytics or crash-reporting SDK. We do not measure how you use the app. We collect nothing.
Diagnostics
Earhythm keeps a small local log to help you diagnose a problem. It stays on your device unless you choose to export it, using the Export action in Settings, which opens your system's file picker so you decide where it goes. Nothing is sent automatically.
By default the log replaces file paths and media locations with placeholders. You can turn that redaction off in Settings if you want the detail in a report you are sending somewhere yourself.
Deleting your data
- Settings → Privacy → Clear diagnostic events erases the log immediately.
- Uninstalling Earhythm removes everything else: the library index, your
corrections, moods, playlists, queues, history, and any cover art you chose.
Uninstalling does not touch your actual music files. Earhythm does not own them, and removing the app leaves them where they were.
Children
Earhythm is not directed at children and we do not knowingly collect information from them — the current version collects nothing from anyone.
Changes to this policy
If this policy changes, the date at the top will change with it.
