Current User Sync With Recontre

I have a dating site where i have been using Users Ultra Plugin for member profiles etc. I don’t think it’s suitable for a dating and would love to switch to Recontre. Since users are already synced in with wordpress if i where to switch to your plugin would the users be automaticlly be synced in with Recontre or would i have to use a csv file for the users already registered.
