Terms of use

• You must be 13 or older to have an account.
• One account per person, with a real email address you can receive mail at.
• Keep your password to yourself. What happens on your account is treated as you.

The Free plan is free forever and needs no card. Premium adds the full set of modules, daily questions, live lessons and exam papers — exactly what the pricing table on the front page says, at the price shown there.

• Payments are taken by Stripe. We never see or store card details.
• Premium renews automatically until you cancel. Cancel any time — you keep Premium until the end of the period you have already paid for, and are not charged again.
• If a payment fails, your account simply drops back to Free. Nothing is deleted.

The site is for your own practice. A few things aren’t allowed:

• Copying or republishing the questions, papers or solutions — they’re written for this site and belong to it.
• Scraping the site, probing it for weaknesses, or trying to game XP, streaks or the leaderboard.
• Setting a name or avatar that is offensive — other students see them.
• Sharing a Premium account or reselling access to lessons.

Accounts are approved by Krish before course content opens, and an account breaking these rules can be blocked. If an account is blocked unfairly, email privacy@krish.one and a human will look at it.

Live lessons run on Zoom at the times shown on the Lessons page, with the joining link on Premium. Lessons follow the schedule published on the site; a lesson can be moved or cancelled, and the schedule is always the current version.

KRISH.one is a practice aid built with care, and we work to keep it accurate and available. But no practice site can promise a grade, and this one doesn’t: results depend on the student. Occasionally the site may be down, or a question may contain a mistake — if you find one, use the report button on the question and it will be fixed.

Nothing in these terms takes away rights you have by law as a consumer.

You can stop any time. Cancelling Premium keeps your account and progress on the Free plan; deleting your account removes everything, as described in the privacy policy.

These terms are governed by the law of England and Wales. If a change to them ever matters — pricing, what a plan includes, these rules — the change will be announced, and the date at the top of this page moves.
