WCAG/ADA Compliant Notice

A client would like to notify its users that their website is ADA compliant. Let's say the site meets all the criteria to be compliant, and all the copy is written by their legal/copy teams, where would a notification best be applicable on the site?

At first I was thinking a brief snippet in the footer, but that text would generally be small. My next guess would be somewhere in the Privacy Policy, but I'm not sure this topic relates to the "privacy policy."
