That’s interesting- since we have kids that take our phones to play all the time I keep them locked up in a private photos app on my device. Can’t afford to have them all out there on the main photo roll. Maybe the text thing might work. I’d like to kind of bring it up in conversation over dinner but just not sure how to broach it.
Phone security is top for me, passcode or fingerprint to open. For us added assurance, no kids! Alternatively keep them on a USB stick that plugs in the phone. No pics on phone, USB stick kept on person or somewhere safe,
