Audio uploads and generated stems
Uploaded audio and downloaded source audio are staged so the separation service can process them. Generated guest stems use temporary storage for browser playback and downloads.
Guest stems normally expire about one hour after processing. Automated cleanup removes temporary files that remain beyond normal job cleanup. Signed-in users can choose to keep completed mixes in protected storage.
Accounts and saved mixes
Account features use authentication records, profile information, monthly usage balances, saved-mix metadata, and stored stems.
Saved mixes and durable shared mixes remain available until removed through product controls, account cleanup, or a completed support request.
Cookies and browser storage
ytstems sets no tracking cookies of its own. Three kinds of storage can live on your device:
- Authentication cookies, set when you sign in. They keep the session valid across pages and are refreshed as you browse. Signing out clears them. Without them, accounts, saved mixes, and durable share links cannot work.
- Browser local storage, used for small interface preferences kept on your device, for example that a mixer hint has already been dismissed, or the chosen theme. This never leaves the browser.
- Advertising cookies, set by third-party advertising partners. These partners may place and read cookies on your browser and use web beacons, IP addresses, and similar identifiers to select, deliver, and measure advertising.
Advertising on public pages
Public pages may display advertising served through third-party advertising partners. Ad units are not placed inside the mixer player itself. These partners do not receive your audio, stems, account details, or saved mixes.
Where required by law, personalized advertising is shown only after you consent through the consent message on your first visit. You can change or withdraw that choice at any time. You can read how our advertising partner uses data from partner sites and apps.
Reliability and product analytics
ytstems records operational events such as processing stages, failures, performance timings, and aggregate shared-mix activity. Shared-mix analytics use a one-way viewer fingerprint and do not store raw IP addresses in the event record.
Hosting, authentication, storage, processing, and download providers receive data needed to perform their part of the service.
