Is ProtonMailCounter safe?

Clean risk

Shows an unread Proton Mail count by briefly opening a Proton Mail tab in the background.

This unofficial extension refreshes the unread count every 15 minutes. It opens a pinned Proton Mail tab for about 5 seconds and reads the tab title, such as “(1) Inbox,” to determine the count without requiring Proton Mail credentials in the extension.

Where it sends data

Destinations our analysis observed ProtonMailCounter 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.

  • mail.proton.me

    ProtonMailCounter sends data to mail.proton.me. No other extension we have analysed sends data here.
