clipster

Clipster is a Python clipboard manager that can be installed from the AUR:

paru -S clipster

In order to start it, add the command to your ~/.xprofile or however you want to run a command on startup.

clipster --daemon &

Clipster supports persistence out of the box and can be configured to store no history.

Edit the configuration file at ~/.config/clipster/clipster.ini.

[clipster]

# Number of items to save in the history file for each selection.
# 0 - don't save history.
history_size = 0

Note that you can still check your clipboard history with

clipster --select

This will show the entries you've copied, but this data is stored in memory instead of on disk. If you kill the daemon (pkill clipster) and re-run it, you'll see that the history is cleared.
