This calculator uses Google Maps to geocode addresses, calculate driving distances, and generate map previews. Because these are Google services, a Google Maps API key is required. Each user provides their own key, which is stored only in your browser.
How to get a Google Maps API key:
- Go to the Google Cloud Console
- Create a new project (or select an existing one)
- Go to APIs & Services > Library
- Enable these APIs: Maps JavaScript API and Maps Static API
- Go to APIs & Services > Credentials
- Click Create Credentials > API Key
- Copy the key and paste it above
Your key is stored only in your browser's local storage and is never sent anywhere except directly to Google's APIs.
