Your music

Uploads and masters use private storage and our private mastering computer. Access requires your job key. Cloud files expire after 24 hours. Private processing copies remain during the pilot for troubleshooting.

Using the tool

We save your job access on this device so you can return to your download. Clearing browser data removes that access. We store a protected fingerprint of your IP address to enforce the three-master allowance, rather than storing the raw IP for that purpose. We record processing times, errors and download requests to operate and improve the service.

The mastering form does not ask for your email address or phone number.

Advertising

When advertising is enabled, Google and its advertising partners may receive your IP address, browser information and page information, and may use cookies or similar storage to deliver ads and measure their performance. We do not include your music, filenames, job keys or mastering settings in ad requests.

Available consent and opt-out choices appear through Google’s privacy messages. Use “Ad privacy choices” on the home page to revisit those choices when ads are enabled. Google also provides a “Do Not Sell or Share” link where its US privacy message applies. Where your browser sends Global Privacy Control, this site leaves Google ads off. Advertising is optional for using the mastering tool.
