Last updated 7 October 2026
The short version
You can
Learn, practise and teach with every lesson. Reuse the short code examples in your own projects, personal or commercial, without credit. Link to any page.
Please do not
Republish the lesson text, diagrams, the Finch character or the site design as your own, or copy them into another course or website.
Using the lessons
You may use PlainFinch to learn, to teach and to practise, at home, at school or at work. Teachers may use lessons in class and send students to them. You do not need to ask.
The code you write
The code you write in the editors is yours. It stays in your browser unless you share it with a link.
Code examples in the lessons
You may copy the short code examples from the lessons into your own projects, personal or commercial, without credit. They are there to be used.
Lesson text, diagrams and design
The written lessons, diagrams, illustrations, the Finch character and the site design belong to PlainFinch. Please do not republish them or copy them into another course or website. Quoting a sentence or two with a link back is fine. Linking to any page is always welcome.
No guarantees
The lessons are written and tested with care, but PlainFinch is provided as it is, without any warranty. Check anything important before you rely on it, especially security advice and anything you put on a live website. PlainFinch is not responsible for how you use what you learn.
Changes and contact
These terms may be updated from time to time, and the version on this page is the current one. Questions are welcome at hello [at] plainfinch.com.
