subscription!

Thanks for your input. The plugin is open-source and free to use.

A subscription is required to use our service to manage data and keep things in sync. We also offer premium support to our paid users.

You are welcome to develop your own data and syncing solution to use with the plugin. But, we do not offer support for that.
