You cannot literally hack Snapchat location but you can monitor it. Here’s how:
When Snapchat enables users to share their location with friends. In this case, the location sharing is turned on on Snap Map. For strangers, the only solution is to monitor snaps on Our Story. They are shown on the Map regardless of the selected location setting.
One can use spyware to monitor Snapchat in overall. Usually, it’s Snapchat messages that are being tracked the most by users. If a person shares location to let their companion know their whereabouts at this particular moment, Snapchat trackers can catch it successfully as any other shared content (texts, links, photos, videos, etc.).
