I have been traveling a lot lately, and it feels like every trip leaves some new junk behind. Hotels, airlines, booking sites, car rentals, airport WiFi, restaurant waitlists, local apps, all of them want an email or phone number.

Then a few weeks later I am getting random calls, weird texts, and emails from places I barely remember using. How would I go about kinda circumventing this and also stay more "privacy conscious" if that's even a thing while travelling. Appreciate it!
