You shouldn't really have a need to use "McDonalds WiFi" anyways, or just Public WiFi at all. I'm sure 4G/5G (if that's a thing? idk im a boomer) is enough. Or you could always just talk with your family instead of looking at your laptop/phone/tablet.

Incognito won't save you. All Incognito mode does is not store: (based on Google Chrome's Incognito mode)
 * Your browsing history
 * Cookies and site data
 * Information entered in forms

If you're very concerned about your privacy, purchase a VPN service. (Free VPNs are not as good as paid ones.)

This is starting to get off topic though.
