Every feature is free
An iTool membership adds one thing: the official gateway, so you don't run a server.

Free forever
Monthly: the iTool site + LinkShell
One iTool membership covers several products: monthly includes the iTool site and LinkShell; yearly includes every iTool product. Renewing extends the time you have left.
No features. You just run a gateway yourself; an iTool membership gives you the hosted one instead.
No. Phone and computer are encrypted end to end; the gateway only relays ciphertext.
You are back on Free: every feature stays, and you connect through your own gateway.
Pay with Alipay on itool.tech. The membership lands on your iTool account, and LinkShell reads it from the same account; nothing else to enter. The phone app doesn't sell it: open itool.tech/pro in a browser on your computer.
Both include LinkShell's official gateway. Monthly (¥9.9) also covers the iTool site; yearly (¥99) covers every iTool product.
