Device management enrollment or supervision

I think my iPhone has been enrolled in device management or is being supervised by my boyfriend. He runs a business and for some reason some of his browser history will be in my phone along with pictures from his album and screen shots of my screen are in his phone but look as if they were takin on mine, also I noticed he uses air droid among other remote management apps? I want to know if I am enrolled in any managed or supervised agreements, or what my options are at this point?
