# GSD Task Manager > GSD is a free, open-source task manager built on the Eisenhower Matrix > (urgent vs. important, four quadrants: Do First, Schedule, Delegate, > Eliminate). Privacy-first: tasks live on the user's device (IndexedDB on > the web, an on-device database in the iPhone, iPad, and Mac app) with no > account, no tracking, and no sign-up. Optional OAuth sync (Google/GitHub, > plus Apple in the native app) keeps devices current through a self-hostable > PocketBase backend. Key facts: - Free. No paid tier, no ads, no trial. - Web app: https://gsd.vinny.dev/ (installable PWA, works offline) - Native app: universal iPhone, iPad, and Mac app (SwiftUI), on the App Store and Mac App Store - Open source: the web app and MCP server are MIT-licensed. - This marketing site sets no cookies and loads no trackers. ## Product - [Web app](https://gsd.vinny.dev/): open and use immediately, no sign-up - [Privacy policy](https://gsd.vinny.dev/privacy/): the local-first data model, plainly stated ## AI integration (MCP) GSD ships a Model Context Protocol server so AI assistants (Claude Desktop and other MCP clients) can read and update a user's tasks: list, search, create, complete, bulk-update, plus analytics like productivity metrics and upcoming deadlines.
