I'm not very protective of my data, tbh... At least not about the kind of data that would be stored in the Cloud. I don't think I lose much letting people store my data for me. I know I'm not the norm, but I also think people overreact about data privacy.
That being said, I always back up my data in my local storage at home. I still use Google Photos (now) because it's the default Gallery on my phone, and it's really convenient TBH. I can switch phones and have all my data up and running in a couple of minutes
