Trello is a visual task management tool that helps individuals and teams organize projects using boards, lists, and cards. Launched in 2011 and later acquired by Atlassian, it’s known for its simple, drag-and-drop interface. However, Trello has faced criticism for privacy issues, including a major data leak in 2024 exposing over 15 million user records due to misconfigured access settings. Users have also unintentionally made sensitive boards public, leading to data being indexed by search engines. Additionally, some features have been removed or limited over time, frustrating long-time users.
