Profile Photos Transfers Tinder unencrypted
Both in Android and of iOS version of its app, Tinder waives HTTPS protocol when transferring photos to Eineverschlüsselte connection. In browser, ManHTTPS detects connections to lock that is displayed in Address bar. Data, such as those transmitted in case of purchases or online banking, are thus verschlüsseltund cannot be easily intercepted and read. Even in mobile apps, HTTPS is now standard for user data.
