Quick start
1.How to sign up
Sign up through a referral link to get an extra 30 days. Open the link in your browser, enter your email, check for the verification code and confirm to sign in. Then choose a plan and complete payment.
• The verification code usually arrives within a minute — check your spam folder
• Alipay, WeChat Pay and credit cards are accepted; Alipay is the easiest
• WeChat Pay needs two devices — you can't screenshot the QR code and scan it on the same device
• Your payment isn't tracked — the bank can't see what you bought
2.How to install
On the device you want to install it on, open kaitu.io in a browser and tap "Download the app". The page detects your device's system automatically.
macOS: You'll need to enter your password to authorize the install — this is required. If the system blocks the install, allow it under System Settings → Privacy & Security.
Windows: If a blue security prompt appears, click "More info" to continue. If your browser blocks the download, click "Keep".
iOS: Available directly from the App Store; you'll need your Apple ID password.
Android: If it won't install directly, use "Account → Install on other devices" in the desktop app to help install it.
3.How to use it
The mobile and desktop apps look exactly the same. After signing in, pick a server and tap Connect.
• If a particular website won't load, switch to Global mode. Note that in Global mode, websites in China also go through the proxy.
• Use the floating icon on screen to send feedback at any time — logs are uploaded automatically so our engineers can find the problem fast.
• One account supports 5 devices at the same time — intended for one household.
