CumulusVPN is a decentralized VPN that protects your privacy by design — not just by promise.
NO ACCOUNT, EVER
No sign-up, no email, no password, no phone number. Install the app and it generates a private key right 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 only the minimum routing state, in memory, and erase it when they restart. There is no activity database to leak, sell, or hand over — because it does not exist.
ONE TAP TO CONNECT
Choose a country and tap connect. Modern WireGuard encryption secures your traffic on public Wi-Fi, hotels, airports, and any untrusted network. Fast handshakes, automatic reconnection, and gateway failover keep you protected.
FREE TIER FOREVER
Every install includes a genuinely free tier — no trial, no card, no account. Upgrade to premium for higher speeds whenever you like.
BUILT ON A DECENTRALIZED NETWORK
CumulusVPN servers run as apps on the Flux decentralized cloud, hosted in commercial datacenters by independent operators — not on one company's servers. A more resilient shape for a VPN.
OPTIONAL MULTI-HOP FOR MAXIMUM PRIVACY
Turn on multi-hop and your traffic passes through two servers, so no single server ever sees both who you are and where you are going. It is slower — we show you exactly how much — and it is your choice, off by default.
HONEST ABOUT WHAT A VPN CAN 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.
PREMIUM IS MANAGED ON THE WEB
Premium speed is optional and is purchased with FLUX cryptocurrency from your own wallet on our website. Once your key is upgraded, your phone unlocks premium automatically. The app itself does not ask you for money.
Powered by Flux Cloud. Privacy that is structural, not a slogan.
Permissions: CumulusVPN uses Android's VpnService to create the encrypted tunnel. That is the only sensitive capability it needs. It does not request your location, contacts, camera, microphone, or storage.
