What gets stored without you noticing
Phones commonly embed the exact location a video was recorded, along with the device model and a precise timestamp. That is convenient in your own photo library and a genuine privacy problem the moment the file leaves it — a clip shot at home carries your address in a field anyone can read with free software. Cameras add serial numbers that can link separate files to the same body, and editing software adds its own identifiers. Inspect the file before deciding: people are routinely surprised by what is there.
