Potentially hacked account

I was scrolling back in my diary which I use rarely and sporadically and found a very extravagant daily input that I could have never put in. It uses ingredients I don't ever use like beef tongue among many others for what looks like some kind of blow out sushi recipe at around 4700 calories. Not that any of that matters, but I know I didn't input it myself.
Contact/Chatbot is useless. So what next, Cronometer?
