Don't have cloud enabled and sharing by default. Also use strip tags software to erase your geolocations from the pictures you take. And if take sensitive pictures (children in your house, sexy time with SO, police doing a crime, etc) definitely move them to an encrypted container and use a wiper too to get rid of them from your normal storage.

And yeah, I used the TrueCrypt as an example because is the most recognizable name in this, but in my particular setup I use VeraCrypt, as pointed by someone else. Wasn't aware that VeraCrypt got so popular. Before VeraCrypt I used Jetico Bestcrypt containers but those weren't public source.
