Privacy

We do not keep your music, and it is not used to train AI models.

Your music

Music you load is sent over an encrypted connection to our analysis provider, Music.ai, which returns key and chord data. No copy is stored on Dream Art Music's servers.

Music.ai's terms (section 7c) do not allow them to train AI models on your music, and we have not given them permission to.

Music.ai holds the file while it works. Their terms permit them to retain it afterwards in anonymised form.

What we hold

Your name and email address, so that you can sign in. Key Matcher stores a copy of every road map it makes. We need to understand how the app is being used so we can continue to make it better. We run no advertising and no third-party analytics, and we do not sell or share your information.

A single sign-in cookie keeps you signed in. Your interface preferences are saved in your own browser and never reach us.
