My name is Theodore Chu. I also go by Theo, Ted, and Teddy, but I always introduce myself as Theodore. I am a United States citizen. I reside in San Mateo.


I'm still trying to figure out what I want to do for my career. I'm currently pursuing software engineering. In the meantime, I'm trying to do my part to ensure that our technology, government policies, and institutional practices respect and protect our rights, freedoms, and liberties.


My formal training has been focused on philosophy, mathematics, and science. My personal training has been focused on computer science and technology with a focus on web development and information security. I like to read, but I read slowly. You can find some of the books I've read here.


I write in English and develop software for Standard Notes, a free, open-source, and end-to-end encrypted notes app that is a safe place for your notes, thoughts, and life's work. You can find my writing on my blog here and on the Standard Notes blog here.

I also developed and shipped a free and open-source custom front end called the Append Editor. It is licensed under AGPL-3.0-or-later and is free to use. You can read more about it here and try it here.


I support free and open source projects that help people communicate and spread information. The free flow of information is important to democracy. I contribute financially to Ghost, Docusaurus, and Wiki.js. My contributions are via Open Collective and GitHub Sponsors. I also donate to Signal, Cryptomator, and Wikipedia.
