I don't see how this could possibly work. I'm root on my machine, how could a software that some other people use can prevent me to do whatever I want with data that my machine receives? In the worst case, I can screenshot anything that appear on my screen. The app claim to be screenshot-proof. I call bullshit.

Yeah this can't work for the same myriad reasons DRM can be circumvented: https://en.wikipedia.org/wiki/Digital_rights_management#Meth...

Snapchat, but it lets you publish your pictures? Also, it stole the name of a popular Cydia tweak for Snapchat. [0] Also, they left what seems like a fake review of their own product on Google Play. [1]

How can you prevent me to take a photo of my screen?

Hacker News really needs some feature to down-vote ... ;-)

You can, once you reach a certain karma threshold.

All this is unofficial, but based on my own observations:

You can never down-vote a submission. When you have enough karma you can:

* Down-vote comments

* Flag comments

* Flag submissions

Flags on submissions affect their ranking in a manner similar to down-voting, except that enough flags can result in a submission being deleted entirely.

Flags never delete a submission entirely. We don't delete submissions unless users ask us to (and have a good reason). Everything else remains visible with 'showdead' turned on in your profile.

I'd say that you might not have enough karma to have access to all the features.

Are you suggesting that with enough karma one can down-vote a submission? I certainly don't have enough karma yet.

Only Paul Graham knows.

Or any of the others who work on the code. However, even jacquesm[0] - third on the leader board[1] - says that to the best of his knowledge one cannot downvote articles:

There are no downvotes on stories, unless you consider flagging a kind of story downvote. That's a legitimate way to look at it, since it answers the complaint upthread [1]: if you think that a story is not appropriate for HN, that's what flagging is for.

Oh, how about "no."

Screenshot?

Yea. On the Play Store, there is litterelly a screenshot of the app displaying a picture, above the text presentation which claim that the app protect against screenshots… This is so lame.

maybe you want to reconsider lying in the description?
