Using popular Online Dating app – Tinder on iPhone?? Then you are at significant risk that exposed members’ private information without their knowledge. Security flaw was discovered by the company last October, that enabled any member with some programming skills to access the app’s API (Application Programming Interface) to get the exact latitude and longitude for another member. Tinder implemented security measures “shortly after being contacted” by Include Security, and did not respond to further inquiries from the company because it does not usually share the specifics of Tinder’s security measures.
