ZZZ HostLink

ZZZ HostLink turns your smartphone into a Bluetooth keyboard/mouse for your PC, and also works as a remote terminal to operate your PCs and servers.
No accounts, no dedicated servers. All communication happens directly
between your device and the destination — never through our servers. And
there are no ads.

■ Bluetooth keyboard/mouse (HID)
Pair your phone to a PC as a Bluetooth HID device and use it like a
physical keyboard/mouse. Works with Windows, Mac, and Linux — handy for
presentations or whenever a keyboard isn't within reach.

- Simple mode: a clean screen with frequently used keys (arrows, Enter,
etc.)
- ABC mode: a soft keyboard with letters, symbols, and function keys
- Mouse mode: trackpad gestures (move, tap, left/right click, vertical &
horizontal scroll, drag)

■ Remote terminal
Operate a PC or server terminal right from your phone. A built-in
VT100/ANSI-compatible emulator handles cursor movement and screen control.
Choose from three connection methods:

- BLE: connect directly to Mac/Linux (run the included Python script on the
PC)
- Wi-Fi: connect to a PC on the same LAN over TCP (use this for Windows)
- SSH: connect directly to a server. Password and public-key authentication
are supported, including OpenSSH keys and PuTTY .ppk (v2/v3)

■ Handy terminal features
- Direct console input (type in place, like TeraTerm)
- Works with both hardware and software keyboards
- Copy & paste, horizontal scroll, block cursor
- Automatic screen-size sync, screen-orientation lock

■ Secure storage of SSH connections
Save the servers you use most. Credentials such as host, username,
password, and private key are stored encrypted on your device
(EncryptedSharedPreferences) and are never sent to our servers.

■ Premium (subscription)
The free version lets you save 1 SSH server. Subscribe to Premium to save
unlimited SSH servers. You can cancel anytime from "Subscriptions" in the
Google Play Store.

■ Privacy
- No ads, no analytics, no operator servers
- Keystrokes, terminal traffic, and connection details are never sent to
our servers
- No access to location, microphone, camera, or contacts

The PC-side connection script is open source:
