OptMeowt

OptMewot sends Do Not Sell signals to all domains a user visits when browsing the web. Such signals must be respected for California consumers per the California Consumer Privacy Act (CCPA), Regs Section 999.315(d). However, many companies respect such signals even when they are sent from outside of California.

OptMeowt currently sends Do Not Sell signals using five methods:

• A new HTTP Do Not Sell header we are developing in a proposed specification effort at the W3C.
• The existing DNT header, which is interpreted by some publishers as a Do Not Sell header.
• The IAB CCPA Compliance Framework for Publishers & Technology Companies, implemented in a first party cookie.
• Third party cookies of ad networks participating in the DAA's CCPA Opt Out Tool for the Web.
• Custom headers and cookies used by individual websites maintained and updated in a Do Not Sell list.

Customizing which Sites Receive Do Not Sell Signals Every domain a user visits will be automatically added to a domain list and will receive a Do Not Sell signal by default. However, users can exclude domains that should not receive a Do Not Sell signal. This functionality is available by accessing the domain list from the extension's popup window.
