Cookies and storage
Last updated 9 October 2026
Music Momentos sets no cookies, and uses no analytics, advertising or tracking of any kind. It loads nothing from other companies' servers.
To work, the app keeps some things in your browser's own storage on your device. This is strictly necessary for the features you use, so there's nothing to agree to. Nothing here is shared with anyone, and you can clear it at any time in your browser's settings (site data for this website). Clearing it deletes your ideas from that device, so save your recovery code first if they're synced.
IndexedDB database: MusicMemos
| Store | What it holds |
|---|---|
memos | Your ideas: recordings, chords, sections, notes, tags and sync status |
peaks | Each recording's waveform, for drawing it |
history, audioVersions | Earlier versions of each idea, for undo and History |
tombstones | Ideas deleted for good, until the deletion has synced |
settings | Your library's secret key, previous libraries and whether you've saved your recovery code |
