Last month, we heard reports about security concerns over Snapchat, mostly over third-party apps that are alternatives to the native Snapchat app.
Instead of going after the third-party developers directly, the service went after its own users, giving warnings when the social messenger detected use of a non-native app. After a warning, they follow up with a notice that user accounts will be locked if they do not stop using these third-party apps. The problem is that Snapchat does not have any official APIs for developers to use, so this leads to security issues. Seems mean to go after the users, but apparently their hands were tied.
The problem is worse for users of Windows Phone since there is no native Snapchat app available. Rudy Huyn, the developer behind 6snap, a popular third party Snapchat app for Windows Phone, tried to get an exemption from the crackdown. However, it fell on deaf ears, since 6snap and all third-party Snapchat apps have been removed from the Windows Phone store. Sadly for some users, it also looks like Snapchat has followed through on its intentions to lock user accounts associated with third-party app use. Well, they were warned.
One of Snapchat’s main features is that pictures and chats disappear automatically. They are not stored for any great length of time on Snapchat’s servers. So third-party apps using their own solutions to access the service with no APIs, create a problem out of Snapchat’s control.
We can only assume that Snapchat asked Microsoft to remove all the apps from the Windows Phone store.
