Legal concerns of tracking family members?

I’m considering using a tracking app for my elderly parent, but I’m worried about the legal side of it - is this generally okay?

I tracked my dad with his permission when he started getting forgetful - the key is consent. Most places allow it if your parent agrees or if you have legal guardianship. I use Parentaler since it has clear consent features and keeps everything transparent. Always check your local laws though, and maybe chat with your parent about it first - mine actually felt safer knowing I could find him.
