Complaining about something from years ago (Adobe Reader)

I just wanted to complain that years ago Adobe Reader saved copies of my pdf's through my adobe account on the cloud without me knowing. I don't think they do this anymore now that they have OneDrive but I don't use OneDrive so I don't know. If it was ever hacked the hacker would have all my personal information! This didn't happen recently but I've been thinking about it recently. I'm pissed that they stole my files! If I was warned I would have never used Adobe Reader for files that contain personal information!
