I don't think SnapChat's LLM has access to your location. I think a service that it uses has access to your location and it can't get it directly but it can ask for "restaurants nearby".
Snapchat asks for the location permission through native APIs or obviously geolocates the user via IP. Either way, it’s fascinating that: people don’t expect it to know their location; don’t expect it to lie; the model goes against its own rules and ”forgets” and “gaslights.”
