Barmij is free — forever

Free for every learner and every teacher, in every country.
And not for sale — by anyone.

You may, warmly

• Learn with it — no account, no payment, nothing collected about you.
• Use it in your classroom, your course, your tutoring, your home. Teachers are our guests of honor.
• Share it, print it, project it, adapt handouts from it — with credit to Barmij.

You may not

• Sell it, charge access to it, or put it inside a paid product, paid course, or subscription.
• Run advertising against it or harvest data through it.
• Publish your own version under the Barmij name.

Formally: all content is licensed under CC BY-NC-SA 4.0 (credit · non-commercial · share-alike). Adaptations inherit free-forever — that is the point.

Questions or school partnerships: the Barmij team welcomes you.
