In regard to your discussion, I would recommend a phone application that is quite useful for the purpose. I use an app named “GPS Privacy” that automatically deletes the GPS location tags if the photo is taken in a privacy area – like around your home, school, work, etc. This way you don’t have to remember whether you have the GPS tags on or off. Simply define your privacy areas, and your pictures won’t have GPS coordinates when made in these zones.
Hope this would be helpful for you as well!
