Focani is free
Every test, every difficulty, no daily limit, no account required. There is no paid tier and nothing is held back.
If it is useful, you can chip in
Entirely optional, and nothing changes either way — there is no supporter tier, no badge and no extra feature to unlock. It just helps cover the domain and keeps this worth maintaining.
Handled by Creem, which acts as the merchant of record. One-off — nothing recurring, and no account needed.
Frequently asked questions
What does it cost?+
Nothing. All fourteen tests, every difficulty, as many sessions as you like. No account is needed to play; creating a free one only adds saved scores, your history and the leaderboard.
Why is it free?+
It is cheap to run — the tests are plain browser code with no server-side inference — and it is more useful to us being widely used and linked to than behind a paywall. Classrooms in particular could not use it with a daily cap in the way.
Are you selling my data?+
No. There is no advertising and nothing is sold or shared. Playing as a guest records anonymous usage only; what that covers is set out in full in the privacy policy and on the instructors' page.
Will it start charging later?+
There is no plan to. If that ever changes, what is free today stays free — a lesson plan or a course page that links here should not stop working because our situation changed.
How can I support it?+
Buy me a coffee, tell someone it exists, or link to it from a course page. All three help; the last one helps most.
