CumulusVPN is a decentralized VPN that respects your privacy by design — not by promise. NO ACCOUNT, EVER There is no sign-up, no email, no password, no phone number. Open the app and it generates a private key on your device. That key is your only identity, and it never leaves your phone. NO LOGS, AND WE MEAN IT We do not record the sites you visit, your DNS queries, your traffic, or your connection history. Our servers keep the minimum routing state in memory only — it is erased when the server restarts. There is no activity database to leak, sell, or hand over, because it does not exist. ONE TAP TO CONNECT Pick a country, tap connect. Modern WireGuard® encryption protects your traffic on public Wi-Fi, hotels, airports, and untrusted networks. Fast handshakes, automatic reconnection, and gateway failover keep you online. FREE TIER FOREVER Every install includes a genuinely free tier — no trial, no card, no account. RUN ON A DECENTRALIZED NETWORK CumulusVPN servers run as apps on the Flux decentralized cloud, hosted in commercial datacenters by independent operators — not on a single company's servers. It is a different, more resilient shape for a VPN. OPTIONAL MULTI-HOP FOR MAXIMUM PRIVACY Turn on multi-hop and your traffic is routed through two servers, so that no single server ever sees both who you are and where you are going. It is slower — we tell you exactly how much — and it is your choice, off by default. HONEST ABOUT WHAT A VPN CAN AND CANNOT DO CumulusVPN protects you from local-network snooping, ISP logging, and geo-restrictions. It is not anonymity software like Tor, and we say so plainly. No overselling. Built by the Flux team. Powered by Flux Cloud. Privacy that is structural, not a slogan. WireGuard is a registered trademark of Jason A. Donenfeld.
