AllTrails, Inc.

AllTrails is a popular fitness and travel application that provides a database of crowdsourced trail maps and reviews for outdoor activities like hiking, biking, and running. The platform operates on a freemium model, allowing users to find, record, and share their outdoor adventures with a global community. While it fosters a community for outdoor enthusiasts, the service's default privacy settings can make user-generated content, including precise location data from completed activities and maps, publicly visible. This public exposure of sensitive location information creates significant risks, as it can reveal personal routines, home addresses, and visits to sensitive locations, potentially leading to stalking or doxxing. Malicious actors could misuse this detailed activity data to track individuals in the physical world. To mitigate these risks, individuals should meticulously review and adjust their account's privacy settings to restrict data sharing to "followers only" or "only me," limit the personal details shared on their profile, and be mindful of the information they are making public.
