How does Bubble use the Google API

Hi there,

I am making an events app for a client and I have a few questions about the usage of the google api.
If a user creates an account which has an address field, and in that address field he or she types Amsterdam. Will bubble use google for finding a corresponding address?

If a user types in a location and wants all events within a radius from that location. How many calls are made to Google?

What if I want to show those events based on the users current location?

If someone has some numbers that would be much appriciated!
