Best phone printing options?

My phone is loaded up with photos and a few years ago I printed a bunch out and made some albums to free up space. I think I used Notions Photo Lab because they had the best first time discount.

A recent concern of mine is "what do these companies do with the photos I send them?" I want to do this same thing with my entire camera roll to free up space and save photos in a cooler way (ie. albums and shoeboxes). I don't want to end up in some AI slop cause they have 6000 photos of my entire life.

My questions: Where do you recommend I print my iPhone photos? Is it a concern for them to have all my photos? Can I just go to a photo printing shop and have them do it? Is there a better way to do this DIY (like a Cricket or something?)

Thanks in advance!
