What Instagram does to your EXIF (and what it misses)
Instagram strips GPS from the visible post in most cases, but the original file you uploaded may still carry it for some surfaces — story downloads, "send original" DMs, third-party scrapers, and certain backup services. The platform's behavior also changes over time as their pipeline updates. The safest approach is to never let the GPS leave your device in the first place: strip it locally before upload.
