They are a great company and are worth supporting in my opinion, they do care about privacy, are based in Switzerland of which was chosen as the location for its strong privacy laws and commitment to protecting user data.
Edit: they just emailed me announcing that they have a 40% end of year sale right now. (absolutely not affiliated)
I wish they could just sell email addresses for those that are hard up for money, but for me, I ended up paying for the mid-tier package for aforementioned reasons.
