Privacy Policy
The public app is local-first.
Effective May 26, 2026. The public launch is accountless and does not provide hosted libraries, hosted favorites, cloud sync, billing, or sign-in.
| Area | Where it lives | Notes |
|---|---|---|
| Browser saves | This browser, this origin. | Favorites, saved patterns, display preferences, and backup imports use IndexedDB and localStorage. |
| Private MIDI folders | Your machine and browser storage. | Selected files are read in the browser. DrumBeet stores generated phrase data, not raw private MIDI files. |
| Hosted requests | The static app host. | Ordinary web request metadata may be received while serving pages, assets, corpus files, audio, and models. |
1. Browser-local data
Favorites, saved patterns, display preferences, and backup imports are stored in your current browser using IndexedDB and localStorage. This data is origin-scoped and may be lost if browser storage is cleared.
2. Local MIDI folders
When you choose MIDI files or a MIDI folder, DrumBeet reads supported files in your browser, mines drum phrases on your machine, and stores the generated user corpus in IndexedDB for this origin. Private MIDI files are not uploaded to DrumBeet.
File and folder selection grant the browser read access to the files you select. Some browsers describe folder access as permission to view or copy files; DrumBeet stores generated phrase data, not raw private MIDI files.
3. Server requests
The hosted app receives normal web request data such as IP address, user agent, requested URL, timing, and error logs when serving the app shell, audio, model, and public Groove MIDI static assets. These requests are not account routes and they do not create hosted user libraries.
Edited patterns, browser-local favorites, saved patterns, and browser-local user corpus data are handled in the browser.
4. Third-party assets
DrumBeet bundles public app assets and loads selected public Magenta model checkpoints from Google's public Magenta checkpoint URLs for model-backed browser tools. External links are governed by their own policies.
5. No account sale or advertising profile
The accountless public launch does not collect sign-in credentials, payment details, account identities, or advertising profile data. DrumBeet does not sell personal information and does not use private MIDI imports for ad targeting.
