[Logseq](https://logseq.com) is a platform for knowledge management and collaboration. It focuses on privacy, longevity, and [user control](https://www.gnu.org/philosophy/free-sw.en.html).
The server will never store or analyze your private notes. Your data are plain text files and we currently support both Markdown and Emacs Org mode (more to be added soon).
In the unlikely event that the website is down or cannot be maintained, your data is, and will always be yours.

Logseq is hugely inspired by [Roam Research](https://roamresearch.com/), [Org Mode](https://orgmode.org/), [Tiddlywiki](https://tiddlywiki.com/), [Workflowy](https://workflowy.com/) and [Cuekeeper](https://github.com/talex5/cuekeeper), hats off to all of them!
Logseq is also made possible by the following projects:
- [Clojure & ClojureScript](https://clojure.org/) - A dynamic, functional, general-purpose programming language
- [DataScript](https://github.com/tonsky/datascript) - Immutable database and Datalog query-engine for Clojure, ClojureScript and JS
- [OCaml](https://ocaml.org/) & [Angstrom](https://github.com/inhabitedtype/angstrom), for the document [parser](https://github.com/mldoc/mldoc)
- [isomorphic-git](https://isomorphic-git.org/) - A pure JavaScript implementation of Git for node and browsers
- [sci](https://github.com/borkdude/sci) - Small Clojure Interpreter
We have [a dedicated overview page](https://github.com/logseq/logseq/blob/master/CODEBASE_OVERVIEW.md) for Logseq's codebase overview and [a development practices page](docs/dev-practices.md).
There are more guides in [docs/](docs/), e.g. the [Guide for contributing to translations](docs/contributing-to-translations.md) and the [Docker web app guide](docs/docker-web-app-guide.md)
