Due to one of Snapchat's features that the messages will disappear after few seconds after sending out, the Federal Trade Commission (FTC) investigated the company for misleading practices since the recipients still able to retrieve the messages either through screen capture function or from other apps or use another device to capture the image. There were some incidents reported that intimate photos had unintentionally surfaced to the Internet. Many parents are concerned and angry about their young kids using Snapchat since it used as a sexting tool or unknowingly exposed privacy information to the Internet. In Snachat Guide for Parents, it said it's prohibited for a child under 13 to use it, but Snapchat doesn't ask for age on signup.
For Windows Phone users, the Snapchat app won't be available in the Microsoft store at all since it's not a matter of bridging the technology. The Snapchat company purposely does not want to develop the app for Windows devices. The company suits anyone third-party developers tried to develop such app in the Microsoft Store. For example, in late 2014, Rudy Huyn created a Snapchat client app called 6snap, was forced to pull out from the store. Just recently, February 2016, a Windows app called Specter was made available by another developer which costs $1.49. We are not sure the faith of this app and how long it will last. The Snapchat users who downloaded 6snap last time had their Snapchat accounts warned and locked by Snapchat. The controversial history of Microsoft's mobile platform is likely to continue.
