Looking for a way to keep control of the privacy of your texts while raising money for THON? Cyber Dust, the Mark Cuban-backed application that has been called “WhatsApp meets Snapchat,” will make a donation in the name of the most active Penn State organizations on the app.

After a dust up with the SEC, which Cuban discussed at Tech Crunch Disrupt, he decided to put together an app that makes sure you don’t lose control of your messages. Cyber Dust, which has nearly 3,000 users at Penn State already and is now launching in earnest, is a texting app that deletes your messages after 24 seconds, and doesn’t store them anywhere. It assures arguably the highest level of privacy available, and has recently added features like emojis, MMS, and group messages. Best of all, it’s free.

Now, the billionaire is looking to reward the most active users of his app with a donation to THON. The organizations with the most users and activity will both receive a yet-to-be-announced amount to go toward their THON total. The contest runs through Dec. 31, and standings will be posted each week to track who is in the lead.

Download Cyber Dust and help raise money for your THON org while messaging worry-free.
