Bigstring Corp. announced that it has launched a beta version of PrivateString, a private wall application for Facebook, iPhone, Android and privatestring.com that incorporates the company's patented self-destructing messaging technology. PrivateString allows users to connect with their friends and share private messages, photos, comments, likes and dislikes in a social wall format. All users can instantly self-destruct their messages or set their messages to self-destruct at a predetermined time. Messages posted on PrivateString are permanently deleted from its servers once they self-destruct. The PrivateString social privacy application allows for multiple group conversation to occur simultaneously, but only those in the initial group can respond with comments or likes. PrivateString is available as a free Facebook application and web application on privatestring.com, and a mobile version also is available for the Android and iPhone at a purchase price of $1.99. An ad supported version is available for Android, and the iPhone free version has been submitted for approval to the Apple App store. The PrivateString application works across its various platforms to connect users, whether they are on Facebook, any of the mobile apps or the PrivateString website. Additional privacy features include private direct self-destructing messages, responded to message thread with self-destructing photos and a dislike button. Future features currently in development are private message and user photo galleries.
