What we often hear
In small towns, staff look after the computers themselves. Klystor handles the most common situations.
- “The disk is full, the software won’t update”Klystor finds the caches, logs and old installers taking up space, and removes them without touching documents.
- “The front desk computer has been slow for months”A nearly full disk slows the whole computer. A few freed gigabytes are often enough to bring back its speed.
- “We don’t know what we can delete”Klystor explains each item and its risk, and only preselects what rebuilds itself.
- “The budget won’t cover replacing everything”Keeping working computers for a few more years saves money and avoids waste.

Frequently asked questions
Is it GDPR compliant?
Klystor processes no data outside the computer: it sends no file, file name or usage statistic. It therefore adds no processor to your records of processing.
Do we need a public tender?
For modest amounts, usually not: under €40,000 excl. VAT, French public buyers can purchase on a simple quote, without formal advertising or competition. We provide the quote and the invoice.
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).
