Remove WP-HR and database entrys.

Hey all, I tried out this plugin, but it’s much more than I will ever need feature-wise, so we’re going with a more simple approach. However, I made the rookie mistake of adding this to a semi-live website. When I remove the plugin it leaves behind a lot of database entries, and I’m by no means good enough to remove them.

Is there a way to remove this with the plugin, or does anyone know a plugin to do the job? I know some other plugins have the option to delete all the data, or even have a separate plugin to remove it.

Many thanks in advance.
