How can we help?

No account needed — most answers are right here. There's no login and no password, so there's nothing to recover. Still stuck? Email us.

Getting started

What is CumulusVPN?

A decentralized WireGuard VPN that runs on the Flux cloud. One tap routes your traffic through datacenter nodes worldwide. No account, no logs.

Do I need an account?

No. On first launch the app generates a WireGuard key on your device — that key is your only identity. No email, password, or phone number, ever.

How do I connect?

Open the app, pick a country, and tap connect. On the first connection your phone shows a standard operating-system VPN-permission prompt — approve it once.

Is the free tier really free?

Yes, forever. It's capped at 100 KB/s (fine for browsing and chat), with no payment details and no trial.

Which countries can I use?

Every gateway in the fleet — 30+ countries at launch — and the list updates live from the network.

Privacy & security

Do you keep logs?

No activity logs. Gateways hold minimal routing state in RAM only, erased on disconnect or restart. Your browsing, DNS queries, and traffic are never recorded. See the privacy policy for the full detail.

What is my "key"?

A WireGuard keypair generated on your device. The private key never leaves your phone; only the public key is shared, to route your tunnel. It's a pseudonym, not tied to your identity.

What can a gateway operator see?

Like any VPN exit, real-time encrypted flow metadata — but no log we create, and never your traffic contents. Turn on multi-hop so no single server sees both who you are and where you're going.

What is multi-hop?

It routes your traffic through two gateways, so no single server sees both your IP and your destination. It's slower — the app tells you how much — and it's off by default.

Is this like Tor?

No. CumulusVPN protects you from local-network snooping, ISP logging, and geo-restrictions, but it is not anonymity software like Tor. We say so plainly.

Premium & payment

How do I upgrade to premium?

On the web at vpn.cumulusvpn.com — with FLUX from your own wallet (cheapest) or by card, Apple Pay or Google Pay. In the iOS and Android apps you can subscribe through Apple or Google instead. Your device unlocks on its own about a minute after payment confirms.

What is FLUX and how do I get it?

FLUX is the cryptocurrency of the Flux network. Buy it on an exchange and hold it in a wallet such as Zelcore or SSP, then pay from there.

How does my device unlock?

Your entitlement is computed from the public blockchain and keyed to your public key, so every gateway flips that key to full speed within about a minute — on all servers at once, for 30 days. It unlocks the one device holding that key, not your account.

Can I prepay several months?

Yes. Send a multiple of the monthly amount and the extra months stack (up to 24).

Do you take credit cards?

Yes. On the web, cards, Apple Pay and Google Pay are handled by Stripe; in the apps you can subscribe through Apple or Google. The processor holds your payment details — we never see them, and there is still no account. Paying in FLUX from your own wallet stays the cheapest option.

I paid — why is my other device still slow?

Premium is tied to a single device key, not to a person, because there is no account to attach it to. Each device generates its own key and needs its own payment. To pay for a phone from your computer, open the app → Settings → About, copy the Device code, and paste it into the box on the upgrade page.

I sent FLUX with the wrong message, or too little. What now?

Nothing is lost, but it will not unlock on its own. A payment only grants premium if it carries your exact CVPN1: code and covers at least one day. Email support with the transaction id and the Device code from Settings → About, and we will credit it by hand — you will be asked to prove you hold the key. Automated claiming is on the roadmap.

Troubleshooting

The app shows "no gateways" or no countries.

Your device probably has no working internet, or a captive portal (hotel/airport Wi-Fi) is blocking the gateway probe. Reconnect and reopen the app — discovery retries automatically.

It won't connect.

Approve the operating-system VPN-permission prompt on the first connect. If another VPN is already active, disconnect it first, then try again — or pick a different country.

Speeds are slow.

The free tier is capped at 100 KB/s server-side. Upgrade to premium for full speed.

What is the VPN permission prompt?

Android and iOS require your explicit consent before any app can create a VPN tunnel. It's the operating system asking, once — approve it to connect.

How do I fully remove myself?

Disconnect, then regenerate or delete your key in the app's settings. That severs the pseudonymous link; gateway state is RAM-only and already clears when you disconnect.
