What data it declares

The developer declares that it does not collect or use your data.

The developer also certifies that your data is not sold to third parties outside approved uses, not used for purposes unrelated to the extension's core function, and not used to decide creditworthiness or lending.

The listing does not link to a privacy policy.

This is the developer's own declaration in the Chrome Web Store. We cannot check it against what the extension does.

What Chrome asks you to allow

When you add it, Chrome asks you to allow it to:

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.

Routine for an extension

Pages it runs its code on

It runs its own code on specific pages only: 1 site pattern.

A content script is code the extension injects into pages matching these patterns. On those pages it can read and change what you see, whether or not a host permission is listed above.

How usual this is for its category

In Productivity · Workflow, 19% of extensions ask for access to every site. This one: No site access.

The typical extension there declares 3 browser permissions; this one declares 1 browser permission.

Counted over the live extensions of the same category after our latest full pass of the store. A share is context, not a verdict: what is normal depends on what the extension is for.

What the store shows

The store shows none of its badges on this listing. Most listings carry none.

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

17victork, who publishes 3 listings we track. This listing has been in the store since 2022-08-17 and was last updated on 2024-02-27.

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.
