Been paying for their service for a few months and have converted some non technical people around me. It is both easy to use and does its job well. The development is very active and also evolving rapidly. It has a fantastic way of crowd sourcing media from various people including people who are not costumers, with a very easy and convenient link. I can wholeheartedly recommend it to anyone, privacy minded or not. It is reasonably priced and works well.
Some few features are WIP, such as face recognition and smart search, but they are a priority as I understand and will likely be finalized soon. In any case, do have a look, they have a free 5GB plan to get started!
PS: I'm just a costumer, not affiliated in any way.
