What gains.tax is and what it never does

This page is a stub. The full guide is written against the shipped app version and is on its way.

gains.tax computes UK crypto tax entirely on your machine. This page will cover what that means in practice, and the short list of things the app will never do, upload your data, require a signup, or charge per tax year.

The full guide lands with the documentation pass for the current app version. Until then the app itself is the best reference, every screen explains what it is doing.
