Is PaperSpan safe?

Medium risk

PaperSpan opens its list page with the stored access token in the URL query string.

When a signed-in user clicks My List, the popup reads the saved access token from local or browser storage and opens www.paperspan.com/mylist with that token in the URL. The token appears in the visible page address alongside a random cache-busting value.

Where it sends data

Destinations our analysis observed PaperSpan contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
