At this time you do have to grant Bumble location permissions while the app is in use in order to be able to swipe on folks in your area.
You can choose from two options:
1. While using the app - Your location will only be updated when the Bumble app is open and being used. It will not update if the app is running in the background.
2. Always - Your location will update when the Bumble app is open and when it’s running in the background. If you don’t want your location to be updated while the app is not open, you can force close the app.
Please note, if you choose never, you will not be able to make any new matches. You’ll be able to correspond with existing matches, but in order to be seen or swipe on anyone new, you’ll need to reactivate Location Services.
