セキュリティ
Practical security decisions — designed for real-world use.
暗号化トンネル
PlainVPN uses modern VPN tunneling with strong encryption to protect data in transit between your device and the VPN server.
キルスイッチとリーク保護
The apps are built to reduce the risk of accidental exposure (for example, if the connection drops). Where supported, kill switch and leak protection features help keep traffic from escaping outside the tunnel.
プライベートDNS
DNS requests can reveal a lot. We aim to keep DNS handling consistent with a privacy-first approach.
