No, Brave (the browser) doesn't send user data to Brave (the company) either. Matching happens on device. Categories are enumerated in the regional ad catalog. Local, on-device machine-learning decides whether a given ad is appropriate for the user. The data which comes back consists of cryptographic attestations; no user data. See https://github.com/brave/brave-browser/wiki/Security-and-privacy-model-for-ad-confirmations https://github.com/brave/brave-browser/wiki/Security-and-pri... for more information. We have also added a way to anonymously detect conversions, such as when a user purchases a product or service after having viewed an ad-notification. This too relies on cryptography, and not user data. Although, if you purchase a product from an advertiser, you are likely already giving them some form of user data (e.g. Name, Address, etc.), but Brave doesn't have/transmit any user-data to ourselves or advertisers.
- annoyingnoob 5y ago> The data which comes back consists of cryptographic attestations; no user data. I'll be honest, I have no idea what that means, other than data going from the Brave browser going to the Brave Ad network. And I cannot see or verify that data. I don't want a browser that is a browser and an ad network, in which case I don't need Brave. I'm interested in how you define 'user data'. Do you mean PII? In my opinion, if I interact with the Brave web browser and Brave creates a log of that then that is 'user data', its not browser data or advertising data. PII is one kind of user data. Data I enter into browser windows is another kind of user data. My interactions with the browser, as generated by me the user, generate user data too.
