How can I backup my Regex Autosuggest Provider settings?

I was just adding a bunch of entries for one particular project and I lost a bunch of them after a crash. Is there a way to manually backup the plugin settings. Is there a particular folder?

That could also be useful for using different settings for different projects. For instance, sometimes a client wants the measurement units in a certain way or the phone numbers formatted in a different way. It would be really useful to have a manual backup of different settings.
