The deal, in plain terms.

Keiko Study is an independent study platform for exams including the GRE, its subject tests, and the GMAT. We are not affiliated with, endorsed by, or an official service of any test owner, and public pages should not be treated as official exam material.

You are responsible for keeping your login secure and for activity on your account. Provide accurate information, keep it current, and let us know promptly if you suspect unauthorised access. One person per account unless we agree otherwise in writing.

Use the platform for your own exam preparation. Do not scrape or resell content, share protected answer banks, attempt to bypass server-side access checks, or disrupt the service for others. We may suspend accounts that abuse these terms.

Currently published public study material is free. Current renewable Pro options are 1 month for €7.99, 3 months for €22.77, 6 months for €43.15, 12 months for €76.70. The 3-, 6-, and 12-month prices are charged upfront for the selected term and include the savings shown on the pricing page. The amount due and billing cadence are shown before you confirm payment. Pro renews at the selected cadence until canceled; cancellation stops future renewals and paid access continues until the end of the paid period when Stripe records that period as active. If account billing controls are unavailable, contact support before your next renewal. Prices may change for future billing periods with notice where required.

We aim to cite official exam documentation and vetted open textbooks for factual claims, and we separate cited exam facts from our own study advice. Study material is for preparation only and is not a guarantee of any score or admission outcome.

The service is provided “as is” without warranties of any kind. We make no promise of specific results, and to the extent permitted by law we are not liable for indirect or consequential losses arising from use of the platform. Nothing here limits rights that cannot be limited by law.

We may update these terms as the product evolves. Material changes update the date above and, where appropriate, are surfaced in-product. Continued use after a change means you accept the revised terms.
