OptMeowt allows Web users to make use of their rights to opt out from the sale and sharing of personal data

With the introduction of privacy regulations such as the California Consumer Privacy Act (CCPA) Web users have a right to limit the sale and sharing of their personal information. OptMeowt automates the process of sending Global Privacy Control (GPC) signals indicating the users' preferences upon visiting a website. Learn more about Global Privacy Control at https://globalprivacycontrol.org/. If you encounter an issue with your use of OptMeowt, feel free to check our FAQ \ Known quirks section at https://github.com/privacy-tech-lab/gpc-optmeowt/wiki/FAQ-%5C-Known-quirks or send us an email. Note: We do not collect any data from you. Third parties will also not receive your data. The permissions OptMeowt is using are required for opting you out. You can learn more and view the source code at https://github.com/privacy-tech-lab/gpc-optmeowt.

Great extension. Just one question. Who would ever want their data to be sold or tracked? Why is there even an option to not send the signals to opt-out? Food for thought I guess

Alrek Arinbjorn·11 Mar 2025

Seems to work well in general, but there are a couple of annoyances! First, when OptMeowt is enabled on Chrome's Extensions page (even if I use its "Disable" option -- the pause button icon in its menu), I can't enter my bank's web site (hosted by fiservapps.com). After login, I immediately get a dialog box with a message from the site: "For security reasons, your session has ended. Log in again." (I sent an email to an OptMeowt developer a couple of months ago about this, but received no response; I now see I can report an issue on GitHub, so I am trying that -- https://github.com/privacy-tech-lab/gpc-optmeowt/issues/441.) Second, when I am in a Google Meet meeting, Meet displays a warning banner saying that I have a Chrome extension that might cause meeting quality problems (linking to https://support.google.com/meet/answer/10550593?hl=en#meet_extension). I narrowed it down to OptMeowt -- when I disable it and refresh the Meet tab, the warning goes away. I haven't actually noticed any quality difference either way, but the banner sure is intrusive, and OptMeowt isn't even intended to be a Meet extension, as far as I know. I assume it must be doing something to trigger Meet's warning. (https://github.com/privacy-tech-lab/gpc-optmeowt/issues/442) As a result, I've had to stop using OptMeowt on some of my computers, and have substituted Privacy Badger, which seems to be decent, with no annoyances so far.
