I have a great relationship with my employer and I don't think anyone is spying on me and I don't care if they read my email. But if I'm logged into their WiFi and I'm using the Tumblr app on my iPhone 6 to view photos and GIFs and occasionally message other Tumblr users, can my employer see the photos I view or the messages I send and receive inside the app?
I don't know that much about it but I was under the impression that using the app was different from visiting Tumblr's website on a computer when it comes to them tracking or viewing my specific activity?
