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

cleanslate, who publishes 3 listings we track. This listing has been in the store since 2024-10-18 and was last updated on 2024-10-18.
