I have serious problem with privacy with your application: I posted a reminder to myself the 31th of december to buy the DNS name exambox.com. Back from vacation, I discovered it has been taken (5 days later actually - see http://whois.domaintools.com/exambox.com) by someone who requestion $1400 to release it!!!
I really don't think it is a coincidence.
From now on I'll stop using your app & will not hesitate to let people know about that fact. If you host your data in a cloud provider, you should check with them.
We can guarantee you that none of the data added to Todoist can or has been compromised. We have the highest security and privacy standards, we're hosted on one of the world's largest and most trusted hosts - Amazon Web Services and use same encryption as online banks do.
We're sorry to hear that you've experienced such issue, but again - none of your data can be accessed even by our staff yet alone third-parties.
