These Terms of Use (the “Terms”) govern your use of EyeKnow O.D. at eyeknowod.com (the “Site”), operated by Eye Know O.D. Ltd., a Colorado limited liability company (“we,” “us,” or “our”). By accessing or using the Site, you agree to these Terms. If you do not agree, do not use the Site.
You must be able to form a binding contract to use the Site. If you use the Site on behalf of an organization, you represent that you are authorized to accept these Terms for it.
Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to access and use the Site for your own personal, non-commercial educational and study purposes. You may not resell, redistribute, or make the Site’s content available to others as a competing product or service.
If you create an account, you agree to provide accurate information, keep your password confidential, and remain responsible for all activity under your account. Notify us promptly of any unauthorized use.
EyeKnow O.D. Pro is a one-time purchase, not a subscription. It gives the purchasing account access to the paid material for twelve (12) months from the date of purchase. It does not auto-renew and you are never charged again. When the twelve months end, the account returns to the free tier and keeps its score history. We do not send a renewal reminder.
Price. The price shown at checkout is the price you pay. We may change the price of future purchases; a change never affects a purchase already made.
Refunds. You may request a refund within seven (7) days of purchase for any reason, no questions asked. Email info@eyeknowod.com from the address on the account. Refunds are issued through Stripe to the original payment method, and Pro access ends on the account when the refund is processed. After seven days, purchases are final except where the law requires otherwise.
Access is personal. Pro access belongs to the account that bought it. It is not transferable and may not be shared, resold, or used by more than one person. Sharing account credentials is grounds for ending access without a refund.
Payment processing. Payments are handled by Stripe. We never receive or store your card number, and your receipt comes from Stripe.
If we end a paid account. If we suspend or terminate a paid account for any reason other than your breach of these Terms, we will refund the unused portion of the twelve months on a pro-rata basis.
You agree not to: (a) scrape, harvest, crawl, or bulk-download the Site’s content or use it to build a competing dataset or product; (b) access the Site through automated means except standard search-engine indexing; (c) interfere with or overload the Site, its security, or its infrastructure, or attempt to gain unauthorized access; (d) reverse-engineer or attempt to extract source code except as permitted by law; or (e) use the Site to violate any law or the rights of others.
The Site and its content — text, questions, compilations, design, and software — are owned by Eye Know O.D. Ltd. or its licensors and are protected by intellectual-property laws. Except for the limited license above, no rights are granted to you. Third-party names, marks (including “NBEO”), and product names are the property of their respective owners and are used only for identification and description; see our Disclaimer.
The Site is an educational resource. Its content is not medical advice and is not a substitute for professional clinical judgment. Your use of the Site is subject to our Medical & Educational Disclaimer, which is incorporated into these Terms by reference.
THE SITE AND ITS CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, ACCURACY, OR NON-INFRINGEMENT. We do not warrant that the Site will be uninterrupted, error-free, secure, or that its content is accurate, complete, or current, or that it will improve any exam result.
TO THE FULLEST EXTENT PERMITTED BY LAW, EYE KNOW O.D. LTD. AND ITS OWNERS, MEMBERS, AND CONTRIBUTORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF DATA, PROFITS, OR GOODWILL, ARISING FROM YOUR USE OF OR INABILITY TO USE THE SITE. OUR TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SITE WILL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US$100) OR THE AMOUNT YOU PAID US IN THE PRECEDING TWELVE MONTHS, WHICHEVER IS GREATER. Some jurisdictions do not allow certain limitations, so some of the above may not apply to you.
You agree to indemnify and hold harmless Eye Know O.D. Ltd. and its owners and contributors from claims and expenses arising out of your use of the Site or your violation of these Terms.
The Site may link to third-party resources we do not control. We are not responsible for their content or practices, and links are not endorsements.
We may suspend or terminate your access to the Site at any time, with or without cause, subject to the pro-rata refund described under “Pro purchases” above. Provisions that by their nature should survive (including intellectual property, disclaimers, limitation of liability, and indemnification) will survive.
These Terms are governed by the laws of the State of Colorado, without regard to its conflict-of-laws rules. You agree that the exclusive venue for any dispute not subject to arbitration or small-claims court will be the state or federal courts located in Colorado, and you consent to their jurisdiction.
We may update these Terms from time to time. We will post the new version here and update the “Last updated” date. Your continued use after changes means you accept them. Changes do not alter the terms of a Pro purchase already completed; the version in force on the day you bought governs that purchase.
