Principles

How I think about building products and writing software.

Privacy

Most people wouldn't want to be tracked or have their information sold to advertising companies. I feel the same way, which is why I use end-to-end encryption whenever possible and do not track users.

Local-first

If it can be used locally, processing is done only on the device and nothing is sent to the server. Network access is limited to the minimum necessary for the user.

Honest, simple pricing

I dislike dark patterns, forced upgrades, and hidden limits. PrivateStater Analytics and my open-source tools are 100% free, and LocalKeys uses a one-time license instead of a subscription. Pricing should be predictable and fair.

Practical over fancy

I value reliability, clarity, and maintainability more than flashy features. A small tool that solves one problem well is usually more helpful than a large platform that tries to do everything.
