Facts, not a score: an ad blocker needs every page and a theme needs nothing, so one number would be wrong about both. Each fact links to its detail.

What data it declares

The listing carries no declaration about the data it collects.

The listing does not link to a privacy policy.

What Chrome asks you to allow

From the permissions it declares, Chrome shows no permission warning when you add it.

Derived from the manifest by Chrome's documented rules; the dialog's exact wording depends on your Chrome version and language. Chrome asks again if an update requests more.

What it can reach

No site access is declared in the manifest, so it cannot read the pages you open on its own.

What the store shows

Has it asked for more over time?

This is the question a permission list on its own cannot answer. An extension that shipped narrow and widened later is a different proposition from one that always asked for the same thing.

The permissions this extension requests have not changed since we started watching it.

Who publishes it

WorldTree Software, who publishes 2 listings we track. This listing has been in the store since 2015-12-14 and was last updated on 2016-04-26.

Similar extensions that ask for less

Listings close to this one in what they say they do, which declare less reach. Less reach is not a verdict on either: compare what each needs for the job.
