Proton VPN Privacy Guide
Privacy claims should be evaluated carefully. This guide explains what a prospective Proton VPN user should review before relying on any VPN provider for privacy-sensitive internet activity.
2. Understand the trust model
Using a VPN moves part of the network trust relationship from the local internet provider toward the VPN service. That makes company transparency and technical security important evaluation factors.
3. Separate privacy from anonymity
A VPN can improve privacy in specific situations, but it does not automatically make every online activity anonymous. Logged-in accounts, browser identifiers, cookies and other services can still associate activity with a user.
4. Review device-level security
A secure VPN connection cannot compensate for an infected device, weak account credentials or unsafe software. Keep operating systems and applications updated and use appropriate account-security controls.
5. Verify current service details
Plan limits, locations, supported devices and technical features can change. Confirm current information from Proton when making a purchasing decision.
