Dallas Mavericks owner and “Shark Tank” host Mark Cuban is worried about your privacy — and he’s decided to do something about it. Cuban has been investing in companies with the goal of keeping your privacy protected in this new social age, and he spoke with TheBlaze about his products when he stopped by the studios in Dallas last week.

“In this day and age, I think it’s imperative you shrink your digital footprint,” Cuban said. Talking about his 10-year-old daughter, he said, “I’m not worried about what she texts, I worry about who she texts it to.”

With that in mind, Cuban has invested in Cyber Dust, an app that offers a text-messaging service with one big difference: the texts self-destruct. If you don’t open the message for 24 hours, it gets deleted, and once you open it, you have 30 seconds before its gone.

“Doesn’t touch a server, it’s not saved on your phone device anywhere, you can’t recreate it,” Cuban said. “It is literally gone forever.”

He also has an iPhone app called Xpire, a service that allows you to delete tweets or to set an expiration date for them.

Cuban uses these services himself and encouraged readers of TheBlaze to add him on Cyber Dust (his username is “Blog Maverick”) where he’ll text with you. The big caveat, of course, is that there won’t be any proof you were actually texting with him.
