Tigertext: helping teens and adults cover their tracks

This is a new app only available on iphones right now but it allows a person to erase texts you’ve sent on another person’s cell phone. Interestingly named Tigertext.  The company that released it promises that it was not named after Tiger Woods but ironically it would have been a program he would’ve benefitted from.  I think this is not something that teaches teens how to use their phones. It bypasses consequences and moves straight to covering up their actions. I will never have this on my phone because I try to create boundaries in my phone useage that would never put me in a place that would cause me to send something I would want to have retracted.  Not using my text messaging past certain hours. My question is: can this really delete poor texting decisions a teen or adult makes? Does the text still get documented somewhere that the authorities could trace it down. I would like to know more information—otherwise we will now have more Sexters unaccountable for their actions.  Shane Hipps makes mention that when you bring in a technology into your life, you gain and you lose.  What do you see the advantages of this technology being and what do you see the disadvantage of this technology being if it were to be introduced into your life or the life of your teens?
