I had a read of the
Privacy Policy. It seems OK. One part they say they "might also request credit card or other payment account information" for certain services.
Also, involving chat logs, "such deletion may not be immediate, and residual copies may remain on backup media."
They may also share your information, but they say it's an opt-in service and they won't do it without your approval.
I won't be using it.
