Michael Mientus (ID: 000000227c13151f) Voted 5 ★ - Updated 09/22/2021 OptMeowt v2.0.1 is a simple extension which sends Do Not Track signals to sites you visit. It does this by sending: * The GPC header. * The DNT header. and setting: * Navigator.globalPrivacyControl * First party cookies of ad networks participating in the IAB CCPA Compliance Framework for Publishers & Technology Companies. * Third party cookies of ad networks participating in the DAA's CCPA Opt Out Tool for the Web. => https://github.com/privacy-tech-lab/gpc-optmeowt/blob/226d225e4543adfbbaa431c18be66904f8878229/README.md README (v2.0.1 Permalink) | OptMeowt | GitHub => https://global-privacy-control.glitch.me/ Interacting with Global Privacy Control For these purposes it works well. This approach has the advantage of working within the system. And it limits the side effects of actively blocking trackers/advertising. The two most off-putting elements of OptMeowt are: * The opt-out cookies which appear in the browser's standard cookie controls. * The automatically generated Domain List within OptMeowt. These give the impression that you are being tracked by generating hundreds of cookies which cannot be permanently deleted and by creating an unofficial browser history which you might not be aware of. While annoying and not explained well, these are harmless. And they are required for the normal functioning of the extension.
