## FAQ
### What is Cenno?
Cenno is a desktop app that lets you control your computer with your hands.
Every action has a spell: point to move the cursor, pinch to click, swipe to
change screens, open Mission Control, change the volume.

### Is Cenno free?
Yes. Cenno is free, with no account and no ads. If you find it useful you can
support it through Ko-fi.

### Does Cenno send my camera feed anywhere?
No. Cenno runs entirely on your computer. There is no server, no cloud
processing and no data collection, so the video never leaves your computer.

### Which computers does Cenno support?
Cenno needs an Apple Silicon Mac with macOS 12 or later and a camera. On
Windows it needs Windows 10 or later.

### Why does macOS block Cenno the first time I open it?
Cenno is an early, experimental release that macOS doesn't recognise yet, so it
asks you to confirm before opening it. Click Done, open System Settings, go to
Privacy and Security, scroll down and click Open Anyway. You only need to do
this once.

### Does Cenno work with my dictation app?
Yes. The hang loose spell toggles dictation in Wispr Flow, Apple Dictation or a
custom shortcut, and a thumbs down removes what you just dictated.
