OptMeowt Extension

With the introduction of privacy regulations such as the California Consumer Privacy Act (CCPA) and the General Data Protection Regulation (GDPR) Web users have a right to limit the sale and sharing of their personal information. OptMeowt automates the process of sending opt out signals indicating the users' preferences upon visiting a website.

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.

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.
