What the signal does
The California Attorney General describes Global Privacy Control as a browser based signal to opt out of selling or sharing personal information. Covered businesses must honor it as a valid request under California law. It does not mean that every business everywhere is covered by the CCPA.
Make your record specific
- Record which browser and device you used.
- Save the setting showing that GPC was enabled.
- Keep the website address and date of your visit.
- Save any message acknowledging the signal.
- If you used another browser or device, record that separately.
What GPC does not establish
A signal does not erase all previously collected information, stop all necessary website functions, or show what a particular company did after receiving it. It also does not make your browsing anonymous. If a concern depends on actual data transfers, the site’s behavior needs separate investigation.
Use official instructions
Browser settings change. The Attorney General’s resource links to information about GPC and supported tools. Start there, then use the instructions for your browser. Avoid extensions from unknown publishers that ask for access to all of your browsing data.
