Could someone tell me if the following command is permanent?

xhost +local:

or is it reset after I close the application, session or reboot?

or do I need to run afterwards the following command to undo the one above?

xhost -

This is definitively not permanent and belongs to the affected X server. If this X server is restarted this setting is lost.

If you want to remove this setting, restart X server or use your command above:

xhost -localhost

(or xhost - to remove all access rights)
