Privacy Policy

Everything Strata does happens locally on your device. When you upload your Spotify Extended Streaming History, those files are processed entirely in your browser. Nothing is sent to any server. Strata has no backend, no database, and no ability to store or transmit your data.

Strata does not require you to create an account. There is no login, no sign-up, and no way for us to identify who you are. We do not use cookies, analytics, or any tracking of any kind. We have no idea who visits this site or what they do here.

Strata uses two external APIs to enrich your results — iTunes Search API for album artwork, and MusicBrainz for release date information. These requests include only song titles and artist names, not any personal data. Please refer to Apple's Privacy Policy and MetaBrainz's Privacy Policy for information on how they handle requests.

If you choose to leave a tip via Ko-fi, that transaction is handled entirely by Ko-fi. Strata does not process or store any payment information. Please refer to Ko-fi's Privacy Policy for details.

If you have any questions about this policy, you can reach out via the Ko-fi page at ko-fi.com/stratamusic.
