## Description

OptMeowt is a Chrome extension designed to empower web users by automating their right to privacy under laws like the California Consumer Privacy Act (CCPA). By sending Global Privacy Control (GPC) signals upon visiting websites, OptMeowt signals your preference to opt out from the sale and sharing of your personal information.

The extension requires necessary permissions solely to send opt-out signals and does not collect or share any of your personal data. It supports user privacy through transparent open-source code, accessible on GitHub. For users encountering issues or wanting to learn more, detailed FAQs and the official Global Privacy Control website provide valuable resources. OptMeowt offers a seamless solution for maintaining your online privacy effortlessly.
