WorkerNavigator: globalPrivacyControl property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

Note: This feature is only available in Web Workers.

The WorkerNavigator.globalPrivacyControl read-only property returns the user's Global Privacy Control setting for the current website. This setting indicates whether the user consents to the website or service selling or sharing their personal information with third parties.

The value of the property reflects that of the Sec-GPC HTTP header.

Value

true if the user explicitly does not grant consent to sell or share their data. false if the user either grants consent, or has not indicated a preference.

Example

js
console.log(navigator.globalPrivacyControl);
// "true" if the user has specifically indicated they do not want their data shared or sold, otherwise "false".
