Is PenX safe?

Low risk

PenX mirrors every open tab's URL, title and favicon, plus all bookmarks, into a local database once signed in.

While a PenX account session is active, the extension records each tab you open or update and imports your full bookmarks tree into its local PGlite store as part of its personal data hub. No third-party endpoint was observed; changes are posted only to a localhost address when a space is set to remote. A content script also accepts login messages from any web page, which can overwrite the stored session.

Where it sends data

Destinations our analysis observed PenX 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.
