Important notes

Browser cleanup removes cache, history and sessions. Cookies are not removed, so you stay logged in. Saved passwords are removed only if the dedicated option is explicitly enabled. The browser must be closed before running cleanup.
User cache cleanup preserves ksycoca6 files required for KDE Plasma to function correctly.
Temporary files removes entries in /tmp not accessed in the last 24 hours, and entries in /var/tmp not accessed in the last 7 days.
SMART summary requires smartmontools to be installed. Without it, the summary section will show no data.
Saved preferences are stored locally in ~/.config/eleora-kleon/settings.json and only contain the selected cleanup options.

How it works

Root operations run via pkexec — a polkit authentication prompt is shown before they begin
User-level operations (cache, browser data, Bash history, recent documents, ABRT user reports) run without elevated privileges and only affect the current user’s home directory
Kleon saves the last selected cleanup options locally in ~/.config/eleora-kleon/settings.json
Kleon does not send telemetry, analytics or personal data. Network access may occur only through system package managers such as DNF and Flatpak during update operations

Privacy
