How do I opt out of ad data sharing?
Quick answer: Go to Settings, scroll to Privacy, and turn off Advertising data sharing. If your browser sends a Global Privacy Control (GPC) signal, sharing is already off.
Steps
-
Go to Settings (or click Privacy in the settings menu).
-
Turn off the Advertising data sharing switch. It takes effect right away. There's no Save button for this one.

What the switch controls
When it's on, CrossBeam shares browsing activity with Google and Meta to measure ad campaigns. When it's off, that sharing stops. Your plans and project data are never shared with ad networks.
Global Privacy Control
If your browser sends the GPC signal (some browsers and privacy extensions do), the switch is off and greyed out with the note "Disabled by your browser's Global Privacy Control signal."
City staff accounts don't see this section. City accounts never share ad data.
