In a recently online leaked database, it has been discovered that the popular keyboard app, Ai.type, has been collecting a large amount of sensitive details on users. The information that has been collected was not necessary for the app to run and ranged from contact information, GPS location to information linked through social media. It was also revealed that user’s contact books from names to phone numbers were being collected.

Part of the problem is that app developers know that very few users understand/read the ToS when they accept “Share my information” on these sorts of apps. I have been trying to educate my friends and family to take a more skeptical view of these kinds of things. That great maxim “If you are not paying for it, you’re not the customer; you’re the product being sold” is a good place to start.
