Your songs stay on your device

Stemroom separates songs on your own device. The audio you add, the stems it produces and your loops and settings are stored in your browser (IndexedDB and local storage). They are never uploaded to us or anyone else. Deleting a song in the app, or clearing this site's data in your browser, removes it.

What is downloaded

The first time you separate a song, your browser downloads the separation model (about 120 to 170 MB) from this site and keeps a copy for next time. If you paste a link to an audio file, your browser fetches that file directly from the address you gave.

What we store in your browser

Stemroom saves your songs, your settings, and your choice about ads in your browser's local storage and IndexedDB. These stay on your device and are not sent to us.

Analytics

Stemroom does not use analytics or tracking scripts of its own, and its fonts are served from this site. Our hosting provider, Cloudflare, may keep standard server logs such as IP address and requested page for security and operation.

Ads

Stemroom is free and paid for by ads. When ads are switched on, they appear on the song library, add-song, guide and FAQ pages, never in the player. Ads are provided by Google AdSense. Google and its partners may use cookies and similar technology to show and measure ads, and to personalise them where you allow it. Stemroom asks before loading any ad code. If you choose "No ads", no Google ad code is loaded.

You can change your choice at any time with "Ad choices" in the footer. You can also manage Google ad personalisation at adssettings.google.com, and read how Google uses data from sites that use its services at policies.google.com/technologies/partner-sites.

Visitors in the European Economic Area, the United Kingdom and Switzerland may also see a consent message from Google. Your choice there applies to ads on this site.

Children

Stemroom is not directed at children under 13.
