Google's Watching - Privacy Sandbox (FLoC) in Chrome

Still, it’s worth checking to see if the feature is active. These steps apply to Android, Windows, Mac, and Linux versions of Chrome:

1. In Chrome go to Settings > Privacy and security > Privacy Sandbox.
2. This opens the Privacy Sandbox page even if you’re not part of the Trial.
3. If the “Privacy Sandbox trials” toggle is turned on, then FLoC is enabled. Click/tap to disable it. Don’t turn it on if you don’t want to Chrome to use FLoC.
