I used the Tumblr app on my smartphone to access some adult Tumblr feeds while on my home network. I also used my phone's internet browser to view some adult content. While all this is completely legal, the Tumblr feed and websites definitely would run afoul of any company's Acceptable Usage Policy.
Later, I went to work where my smartphone automatically connects to my company's WiFi network. It wasn't until an hour after I'd arrived at work that I realized Tumblr and the web browser may still be running in the background on my phone. I'm not sure if the Tumblr app was automatically refreshing in the background, and I definitely did not actually open the app or refresh the site in my browser. However, I'm still worried that the background tasks may have violated my company's use policy by downloading adult content on their WiFi network.
I'm really worried that this activity might be detected and traced back to me. Is this something my company can do, if my phone did access offending content while on the corporate network? Does the Tumblr app or web browser even do any automatic refreshing in the background?
