Data being entered for calories and hydration on Edge 840, I didn't add the data.

I've had data for calories consumed and fluid consumed on Edge 840, Epix Pro, and connect app. added to account when I haven't entered any of this information.  I am not connected to My Fitness Pal either.  No one uses my account and I have changed my password.  There is nothing set up to automatically add calories and fluids to account.  Anyone have an answer?
