How does the km radius work? ~ Nuit
The distance radius is an explore setting that filters profiles to those who are in proximity to your location, closer to you than the parameter’s value. For example, if you choose 50 km as max distance, the application will only show profiles of users that are 50 km or less away from your current location.
If you are exploring in a custom location instead of your current location, the distance radius is calculated from the selected location.
