Browser extension that sends Global Privacy Control signals to opt users out of web tracking and ad targeting.

Browser extensionfreeglobal

OptMeowt is a free, open-source browser extension that automatically sends Global Privacy Control signals to every website a user visits, exercising legal opt-out rights against the sale or sharing of personal data. It also opts users out of Google's Topics API on Chromium browsers. It's aimed at privacy-conscious users who want an automatic, always-on opt-out signal instead of manually declining tracking on each site.
