vpn-api.proton.me: Proton VPN’s Connection Data Handler

The domain vpn-api.proton.me is part of Proton VPN, used to manage user connections and monitor usage patterns. While Proton emphasizes privacy, it still collects data to run its service, which can pose risks if mishandled. Here’s what it does and how to stay cautious.

What Is vpn-api.proton.me?

This domain serves as an API endpoint for Proton VPN, handling connection data and user authentication. It tracks usage to ensure service functionality, but even with Proton’s no-logs policy, some data is logged temporarily, creating a potential privacy concern.

Data It Collects

When you use Proton VPN, this domain captures:

• IP Address: Logs your origin IP before encryption, tied to a region.
• VPN Server IP: Records the server you connect to, showing chosen location.
• Connection Timestamps: Tracks when you connect and disconnect.
• Session Duration: Measures how long you’re connected.
• Data Volume: Logs data transferred during sessions.
• Device ID: Identifies your device for account linking.
• User-Agent: Captures app or browser info, like ‘ProtonVPN App v3.0’.
• Account ID: Ties usage to your account, though anonymized.
• Protocol Used: Records VPN protocol, like ‘OpenVPN’.
• Error Logs: Logs connection issues or crashes.

Even with anonymization, this data can build usage patterns over time.

Who Gets Your Data?

Proton shares limited data with:

• Proton internal team: Uses data for service monitoring.
• Third-party infrastructure provider: Maintains servers hosting VPN connections.
• Analytics tool: Processes aggregated stats without identifiers.
• Cloud provider: Stores data under strict privacy rules.
• Legal authority: Only under Swiss law, per transparency reports.

• Limit VPN Usage Data: Use Proton VPN selectively for sensitive tasks.
• Rotate Servers: Switch VPN servers to avoid consistent patterns.
• Use Privacy Tools: Pair with Privacy Auditor’s services for added protection.
• Monitor Account: Check Proton account settings for data control options.
• Stay Informed: Review Proton’s transparency reports for policy updates.

Stay vigilant to maintain your privacy edge.
