Permissions-Policy: geolocation

The HTTP Permissions-Policy header geolocation directive controls whether the current document is allowed to use the Geolocation Interface.

Specifically, where a defined policy blocks use of this feature, calls to getCurrentPosition() and watchPosition() will cause those functions' callbacks to be invoked with a GeolocationPositionError code of PERMISSION_DENIED.

By default, the Geolocation API can be used within top-level documents and their same-origin child frames. This directive allows or prevents cross-origin frames from accessing geolocation. This includes same-origin frames.

Syntax

http
Permissions-Policy: geolocation=<allowlist>;
<allowlist>

A list of origins for which permission is granted to use the feature. See Permissions-Policy > Syntax for more details.

Default policy

The default allowlist for geolocation is self.

Examples

General example

SecureCorp Inc. wants to disable the Geolocation API within all browsing contexts except for its own origin and those whose origin is https://example.com. It can do so by delivering the following HTTP response header to define a Permissions Policy:

http
Permissions-Policy: geolocation=(self "https://example.com")

With an <iframe> element

FastCorp Inc. wants to disable geolocation for all cross-origin child frames, except for a specific <iframe>. It can do so by delivering the following HTTP response header to define a Permissions Policy:

http
Permissions-Policy: geolocation=(self)

Then include an allow attribute on the <iframe> element:

html
<iframe src="https://other.com/map" allow="geolocation"></iframe>

Interestingly, allow attributes can selectively enable features in certain frames, and not in others, even if those frames contain documents from the same origin.
