Frequently asked questions
Is Klystor suitable for healthcare professionals?
Scanning happens entirely on the computer and nothing is sent. Patient files are never preselected, and every cleanup goes through a dry run and then the Trash.
How many computers can we equip?
A licence covers two computers. Beyond that, we prepare a quote based on the number of computers.
Does Klystor send data from our computers?
No. Scanning and cleanup happen entirely on the computer: no file, file name or usage statistic is sent. Klystor only contacts klystor.app, to check for updates and, with a licence, to validate it. The AI assistant is optional, off by default, and sends nothing without consent.
Can a staff member delete something important?
Klystor refuses system folders and protected app data, runs a dry run before every cleanup and moves everything to the Trash, where it can be restored. Personal files are never selected by default.
Our staff have no administrator rights.
Klystor cleans the user’s account without administrator rights. For installation on a managed fleet, an MSI installer and silent installation are planned for version 1.0: tell us how you deploy software.
Can you invoice through Chorus Pro?
Yes, it will be for organisation plans: quote, purchase order, then an invoice filed on Chorus Pro, paid by bank transfer.
I am an IT service provider.
Let’s talk: we are preparing terms for providers who install and look after Klystor for their clients (discount, licences managed across several organisations).
