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 links 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 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

Testfully. This listing has been in the store since 2021-03-10 and was last updated on 2022-09-11.

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.

  1. ToolsTray CORS & API Client Helper No site access · 3 permissions 4 users (last published figure)
  2. WyngMate: Enable Localhost Testing Access to specific sites only · 2 permissions, 4 site patterns 9 users

  2. Open its details. The site access setting shows where it can run; set it to run only on click and it reaches a page only after you press its icon.
