Privacy
Your unreleased music stays yours.
Most of what people bring here hasn't been released. So the app is built private by default: your audio is gone the moment it's analysed, your results are yours alone, and nothing that could identify your songs leaves our server.
Audio deleted at onceYour recording, and any song you compare it with, is deleted as soon as it has
been analysed. We never keep, play or share it.
Results only you can openA result opens only in the browser that made it, or in your account once
saved. Sharing by link is a switch you turn on.
No names leave the serverThe optional AI ideas get the analysis numbers (key, chords, tempo,
sections), never your audio, file names or titles.
No ads, no trackersNo analytics, no third-party scripts or fonts, nothing sold or shared. Your music
is never used to train anything.
What we keep, and for how long
| What | Kept | Who can see it |
|---|---|---|
| Your audio files (and songs you compare with) | Only while they're being analysed, then deleted | No one |
| A result you haven't saved | 24 hours, or until you press “Delete now” | Only the browser that made it (or anyone with the link, if you turn sharing on) |
| A result saved to your library | Until you delete it, or your account | Only you (or anyone with the link, if you share it) |
| Your library's projects, labels and notes | Until you change or delete them | Only you |
| The analysis cache (numbers worked out from your audio, so re-analysing the same file is instant) | Up to 24 hours, and deleted with the result | No one: it's never shown |
| Your memory (ratings, corrections, goals) | Off unless you switch it on; until you clear it | Only you |
| Which parts of a report you use (the section and how often you unfold it, explore its charts or read it: nothing about the track) | In your own browser; on your account too only with your memory on, until you clear it | Only you |
| Recordings you keep (recorded here, or added to “Your recordings”) | Until you delete them, or your account. They're stored as you made them and only analysed when you pick them | Only you: no one else can play them |
| Results you share with a group | Until you stop sharing, leave the group, or it closes | That group's members (they see your username, the result, and nothing else of yours) |
| Site totals (tracks analysed, accounts, ideas marked helpful) | As running totals | Everyone, on the About page: numbers only, counts under 10 hidden |
| Your text size and look (Professional or Studio) | In your own browser only | No one |
| The picture of a track, and the PNG you save of it | Drawn from the analysis's numbers, as part of the result; the PNG is made in your own browser | Whoever can see the result |
| A track you load into “Listen along” | Never uploaded: it plays from your own device | No one |
| Your account | Until you delete it: a username and a hashed password, no email | Only you |
What leaves our server
- AI ideas (switched on here; you can untick them for any upload): the analysis numbers go to the AI provider to write suggestions. No audio, no file names, no song titles, no account details.
- “Find music like this”, only when you use it: the song names and playlist links you type are looked up on MusicBrainz, ListenBrainz and Last.fm, and a public Spotify or YouTube playlist is read for its song names. Songs you upload there are analysed here, like everything else.
- Nothing else. The style and instrument models run on our own server. Pages load nothing from other sites.
How the site protects it
- Result pages, your library and your profile tell search engines not to index them and browsers not to keep copies in shared caches.
- When you follow a link out of a result (a search link, say), the other site isn't told where you came from, so a result's address can't leak.
- Two small cookies only: your sign-in (it also holds this browser's private key to its own results), and whether you've closed the welcome note.
- Like any website, the server's log records which pages were requested and from where. The site runs behind Cloudflare, which carries the traffic.
Your controls
- Delete now on any result, saved or not.
- Share by link and Stop sharing, on any result of yours.
- Download all your data as one zip, or delete your account and everything in it, straight away.
- What we remember: off by default; see it, edit it, or forget everything.
