5 Your Photo Metadata
When you take a picture with a smartphone, the device will usually tag that picture with metadata detailing where it was taken. If you aren’t careful, this could be used to track down your current location.
Many websites scrub metadata or at least anonymize it. But it’s still perfectly possible for someone to figure out where a picture was taken. Because of that, you should take care of pictures snapped around your house, school or workplace.
