The storage permission

Chrome extension permission · by Alex · checked

We give it no weight when scoring how much an extension can reach: on its own it exposes nothing about you.

Why almost everything asks for it

An extension with no way to save anything forgets your settings every time Chrome restarts. This is the most common permission there is, and on its own it says nothing about an extension at all.

Who asks for it

Out of the 67,225 extensions we have examined, 34,004 declare this permission. These are the largest of them by user count.
