This plugin uses the WP-cron to schedule events which synchronise the data. WP-cron is the system built into WordPress to handle the scheduling of time-based tasks and to simulate a system-cron.

If your site does not get visits regularly and you really want the tasks to run on time – take a look at: Hooking WP-Cron into the System Task Scheduler.

No, you only need to insert the license at the site which is your monitor. In fact, you can use the free version of our plugin on your other sites.
