Enabling Location History allows users to track their locations in Day One and use those to create entries or to add to entries to enhance the metadata details.
Go to Day One > Settings > Location History. This setting uses the location data Apple is already tracking so it does not add impact to battery life.
Please note that privacy is one of our key principles, and we recognize that your Location History is none of our business. Your Location History is never shared with Day One servers or employees; only you have access to it.
