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

mobileapps.primefocus, who publishes 2 listings we track. This listing has been in the store since 2023-09-09 and was last updated on 2023-09-09.
