If you access the Site from a mobile phone, tablet, automobile, or other electronic device, we may collect and store information such as device type, operating system version and type, unique identifiers (such as mobile advertising ID), wireless carrier, and other related information for that device.

The mobile advertising ID bit is especially bad. That one identifier can act as a total fingerprint for the likes of Googs etc.

So yes, another social platform no better than the big bads when it comes to privacy.
