Questions, answered
Is it really free?
Yes. The whole app is free and stays that way. Pro only lifts the cap on how many corp-sec clients you track.
Where is my data stored?
On your device first. Sign in and you get encrypted sync across your devices — nowhere else, unless you choose to.
Does it work on my phone?
Yes. Open koix.cc and tap Add to Home Screen. It installs like a native app and keeps working offline.
Can my accountant use the numbers?
Yes. KoiX keeps real double-entry statements and exports clean CSV your accountant can pick up straight away.
