Absolutely not. Proton VPN enforces the strictest no-logs policy in the industry. Here's how we protect your privacy:

1. Zero-log commitment: We do not record your browsing history, data transfer content, connection timestamps, bandwidth usage, or any personally identifiable information.
2. Swiss legal protection: Proton AG is headquartered in Geneva, Switzerland, governed by the Swiss Federal Data Protection Act (FADP). Switzerland is not part of the "Five Eyes" or "Fourteen Eyes" surveillance alliances.
3. Independent audit verification: Our no-logs policy has been thoroughly audited by independent security firms such as Securitum. Audit reports are published publicly on our website for public oversight.
4. Open source code review: All VPN client code is open source on GitHub. Security researchers worldwide can inspect and verify that there are no backdoors or data collection mechanisms.
5. Technical safeguards: Our server architecture is specifically designed not to store any user activity data, ensuring our privacy commitments are upheld at the technical level.

Proton VPN offers three plans to meet different user needs. Here are our recommendations:

Public Wi-Fi networks (such as cafes, airports, and hotels) typically lack encryption and are vulnerable to hacker attacks. Proton VPN provides multi-layer protection:

1. Automatic encryption tunnel: When connected to Proton VPN, all your traffic is transmitted through an AES-256 encrypted tunnel. Even on unencrypted public Wi-Fi, hackers cannot intercept your passwords, banking information, or private communications.
2. Kill Switch protection: If the VPN connection drops unexpectedly, the Kill Switch automatically cuts off your network, preventing data from leaking in an unencrypted state. This feature is enabled by default.
3. Auto-connect feature: You can set VPN to automatically start when a new Wi-Fi network is detected, ensuring protection every time you connect to a public network without manual intervention.
4. DNS leak protection: Proton VPN uses its own DNS servers for domain resolution, preventing your ISP or network administrator from窥探 your browsing history.
5. NetShield extra protection: Plus users' NetShield feature blocks malicious websites and trackers at the DNS level, providing an additional security layer in public network environments.
