If you want to know something funny, I found in my Google pictures few of someone else's pictures I never took, nor known who that person even is! Nothing sensitive, but none the less, the moral is to never trust any of the online services won't ever leak your data - and always think when you use them as such. I can certainly presume the reverse is quite true, anything stored online, even more so, for free, is subject to being leaked with or withotut intentions. I am seriously considering ceasing use of their services, however inconvenient, and get a paid for secure account. Biggest issue is they all design the phone OS integrated with an ID, and the more we trust one place with all media accounts we have, the higher the risk.
