What Proton VPN is
The extension routes Chrome traffic through Proton's VPN servers as a browser proxy, with auto-connect and, on paid plans, more countries, streaming access, Secure Core, and split tunneling. Free accounts can use it; Proton's pricing page says the free plan connects one device at a time to servers in 10 countries.

Is Proton VPN safe to use?
Proton VPN is one of the safer free VPN extensions: an established Swiss publisher, a stated no-logs policy, only authentication information disclosed, and no data cap on the free plan. Its access is broad because it proxies all browser traffic, and that protection stops at the browser; it does not cover other apps.
Page access Broad
Requests page-content access across sites. Broad access is not itself a red flag — the question is whether the job justifies the reach, and whether the publisher's record earns it.
As a proxy, the extension controls how Chrome routes every request, which is the access its job requires. Proton says it protects only browser traffic: other apps, system updates, and some browser features that bypass proxy settings keep using your real connection, so use the desktop app when you need device-wide coverage.
Store-disclosed data
- Authentication information
The listing names only authentication information, the sign-in data a Proton account needs. Proton describes a strict no-logs policy and says it does not record browsing history; Proton AG in Switzerland operates the service. Hiding your IP address does not stop sites from recognizing you through cookies or account logins.
Does the Proton VPN extension protect my whole computer?
No. Proton's support pages say the browser extension protects only traffic inside your browser, not other applications or system activity. For device-wide protection Proton points to its full VPN apps, which can run alongside the extension.
Is the Proton VPN extension free?
Yes. Proton says the extension is available to anyone with a Proton account, including free accounts. The free plan has no data limit but connects one device at a time to servers in 10 countries; paid plans unlock more locations and streaming.
What data does the Proton VPN listing disclose?
Only authentication information. Proton describes a strict no-logs policy, so the disclosure covers signing in to your account rather than the sites you visit.
