Saves data on external servers

The functionality may be great but the plugin stores the ratings on their servers (which is a no-go for our internal company blog). This could be made more clear before downloading and activating the plugin. (Maybe in the plugin description?)

Plus: I wonder how the plugin can be GDPR/DSGVO compliant without letting users know that this data is being exchanged with a third party. I do not know if this is ok…
