Your voice stays with you, unless you back it up
Making songs happens on your device. Recording, listening to your voice, writing the chords, pitch correction and mixing all run inside your browser. Nothing is uploaded while you make a song.
- Microphone: only used while you're recording, and only after you allow it.
- Songs on this device: saved in your browser's own storage. Clearing your browser data deletes them; you can also delete any song from "Your songs".
- Cloud backup is optional. Only if you create an account and press "Back up" do we store that song: the finished mix, your vocal, its cover picture and its settings. It's kept in private storage (Cloudflare R2) that only you can play, unless you switch on a share link for that song. You can delete it from "In the cloud" at any time, and it's removed from storage.
- Your account: just the name you choose and a passkey (your device's Face ID, fingerprint or PIN). We never see your fingerprint or face, and we don't ask for an email or password. We keep a sign-in cookie so you stay signed in.
- Limits: each account can keep up to 10 songs (100 MB) in the cloud for free.
- No ads, no tracking, no selling data. We don't use analytics or advertising cookies.
- What goes over the internet: the app's own files, the fonts (Google Fonts), the instrument sounds (the midi-js-soundfonts project on GitHub Pages), and, only when you use cloud backup, your backed-up songs to Cloudflare.
- Sharing only happens when you press Share, Save, or turn on a song's share link.
