What is "sender-based" control of messages?

Applies to:

From a privacy standpoint, traditional messaging systems are “receiver-based”, in that the recipient gets to decide how long messages live and how they are shared.

Wickr lets the sender make these decisions, providing far more confidence that their private messages won’t turn up on a lost or stolen phone, becoming stranded on some Internet blog, or resurrect themselves when that social media site they used to use gets hacked.

We created Wickr so that we can communicate safely with our family, friends, and colleagues.

We’ve poured a ton of technology into Wickr to help give control of messaging back to the sender.

We protect messages with multiple layers of the strongest encryption technologies known to man and set them to self-destruct by default so you can rest easy knowing that those private messages aren't floating around longer than you want them to.
