What OpenTodo is

OpenTodo is a free, open-source web task manager for personal lists, daily planning, and small tasks. It organizes work with smart lists for My Day, Important, Planned, and custom categories. Subtasks let you divide an item into smaller pieces, while search and sorting help locate and reorder tasks. Bulk actions can move, complete, or delete several tasks together. Tasks synchronize automatically between desktop and mobile. Wallpapers and dark mode provide appearance options. An OpenOak account connects OpenTodo with other OpenOak apps; the service stores tasks, lists, settings, and related metadata to synchronize them and associate them with that account. OpenOak says it does not sell, rent, or share personal data for advertising or marketing, and that its websites avoid analytics, fingerprinting, ads, and tracking scripts. OpenTodo runs on the web. OpenOak describes its standalone applications as open source, generally under AGPL-3.0-or-later unless a repository states otherwise. It also says OpenTodo is for personal planning and should not be the only record of critical information.
