WireGuard VPN
Your phone or PC connects to your data through a dedicated encrypted tunnel — and there’s no other way in. So even if your password is ever leaked, your data stays completely safe.
Setup is simple. Just scan the QR code sent at signup with your phone. Done in 5 seconds. Think of it as your own private, secure road on the internet — built just for you.

On a normal internet connection, every request you make — “I want to visit this site” — is sent out to external servers. That’s what makes tracking possible.
With katuocloud, those requests never leave the tunnel. Everything stays inside the encrypted connection, so no one on the outside can tell what you’re accessing.
No complicated setup required. Just connect to WireGuard and your communications are automatically secured.
**Complete Device Management**
Each device — phone, PC, or tablet — is configured individually by scanning a QR code. This gives you independent control over every connection.
No stress if you lose your phone. You can cut access for just that one device. Your other devices — PC, tablet — keep working as normal. No password change needed.
Easy to manage across family or team. Assign devices to specific people: “this one is for Tanaka,” “this one is for the accounting team.” Data sharing and separation can be configured through support.
**Customer Support**
Unlike the automated support bots of big-name services, you get direct human support. Identity is verified using the passphrase you set at signup.
Avoid the usual headaches.
- SMS verification failing (lost phone)
- Confirmation emails going to spam
- Password reset emails nowhere to be found
None of those big-service problems exist here.
Fast response, every time. “My device was stolen — please suspend it.” “I want everything deleted.” One message and it’s handled. Available until 10 PM on weekdays.
**Customer Privacy Protection**
All you need to sign up for katuocloud is just these two things:
1. A username — you choose it yourself 2. A passphrase — you choose it yourself
No phone number. No email address.
Why we don’t collect personal information. We’re entrusted with your most sensitive data — and we believe the safest approach is for the operator to have no idea whose data it is. The operator knows neither the contents nor the owner. That’s the strongest privacy possible.
How does identity verification work? Via your passphrase. Even without a phone number or email address, verifying your identity for support purposes is no problem at all.
