Privacy
Short version: BestMastering is a program that runs inside your browser. Your music is never uploaded, and we do not track you.
Your audio stays on your device
Files you open, record or drop in are decoded, processed, mixed and exported by code running on your own computer. They are not sent to any server, because the site has no server-side processing at all. We cannot hear, store or analyse your music.
What is stored in your browser
- IndexedDB: autosave and hand-off data (for example the file you dropped on the start page, so the mastering page can open it, and your recovery copy of a session). It stays on this device and you can remove it at any time by clearing site data.
- localStorage: small preferences such as language, last used settings and layout.
- Cache storage: a copy of the application files so the studio opens offline. User audio is never placed in this cache.
No cookies, no analytics, no ads
We set no cookies, and we use no analytics, tracking pixels, fingerprinting, advertising or third-party scripts. Everything the page loads comes from bestmastering.com itself.
Microphone
Only if you press Record does the browser ask for microphone access. The recording goes into your project in memory and nowhere else.
Hosting logs
Like any website, the hosting provider may keep ordinary server logs (IP address, time, requested file name) of requests for the application files. These contain no audio and no project data.
