Looks like a cool service but sounds somewhat off-putting in that they will have all those data about my behavior. Maybe it would be cool to be able to self-host.
Good to know that the owners are "pretty cool and nice" but that is orthogonal to the point.

Unless open source, the users never know if the data is destroyed or not. Furthermore, it is impossible for the users to verify the checksum of software running on the server side. Therefore on-premise install could be a nice solution.
They're pretty cool and nice. If you send a support request, it will be one of the developers... who are also the owners.
