Terms of Service

These Terms of Service (the “Terms”) are an agreement between you and [Legal entity name] (“we”, “us” or “our”), which operates Cairn. They cover your use of our website and learner app (together, the “Service”). Please read them carefully. Our Privacy Policy explains how we handle your personal information and is part of how the Service works, so please read it too.

We have tried to write these Terms in plain language. Headings are there to help you find things; the text under each heading is what counts.

1. Accepting these Terms

When you set up your profile after signing in for the first time, we ask you to accept these Terms. We keep a record of which version you accepted and when. By accepting, or by using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

If you are under 18, please read these Terms with your parent or guardian. Your parent or guardian must agree to them on your behalf, and by letting you use the Service they also agree to these Terms.

2. Who can use the Service

• You must be at least 13 years old to use the Service. The Service is not directed to children under 13, and they may not create an account.
• If you are at least 13 but under 18, you may use the Service only with the permission of a parent or legal guardian.
• When you accept these Terms, you confirm that you meet these age requirements. If we learn that someone under 13 has created an account, we will delete the account and its information, as described in our Privacy Policy.

3. Your account

You sign in to Cairn with your Google account. Sign-in is handled through our authentication provider, Supabase. We never see or store your Google password.

• Your account is for you alone. Please do not share it or let anyone else practice under your name, and do not sign in to someone else’s account.
• Keep your Google account secure. Anyone who can sign in to your Google account can also open your Cairn account.
• Choose a display name that is not offensive and does not pretend to be someone else.
• If you think someone else has used your account, please sign in and open Support.

You can delete your account at any time with the “Delete account” control on your Account page. Deleting your account permanently removes your sign-in account, your profile, support requests and all of your practice history. See section 11, and our Privacy Policy for how long backup copies may remain.

4. What the Service is, and how it may change

Cairn helps you practice for the SAT®, the PSAT/NMSQT® (PSAT/NMSQT practice is also offered to learners preparing for the PSAT™ 10 and PSAT™ 8/9) and the ACT®. The Service currently offers:

• original practice tests and exercise sets for Reading and Writing and Math (SAT and PSAT/NMSQT practice) and for English, Math, Reading and Science (ACT practice);
• answer review after you submit a set, with explanations where they are available;
• progress tracking, including a record of your practice and badges based on it.

Our questions are not official College Board or ACT questions, and they are not taken from real tests. The Service does not predict your score.

We may add features and correct or improve practice content. We will not remove features or practice content, including content unlocked by a purchase, unless required by law, a regulator, or a court or tribunal.

If we decide to shut down the Service, we will give you at least four weeks’ notice in the Service or by email. During that notice period, you can continue using the practice tests you bought. A shutdown does not entitle you to a refund, except where the law requires one.

5. Acceptable use

The Service is for your own personal, non-commercial study. When you use it, you agree that you will not:

• copy, scrape, download in bulk, sell, publish or otherwise redistribute our questions, answer explanations, glossary or other content, including posting them online or using them in your own course, book, app or tutoring business;
• use bots, scripts or other automated tools to access the Service or collect content from it;
• share your account with others, or use another person’s account;
• try to access other users’ accounts or data, or any part of the Service you are not meant to access;
• try to reverse engineer, extract or reconstruct our answer keys or the way answers are graded, other than by practicing normally;
• interfere with, overload or disrupt the Service, or try to get around its security or access controls;
• use the Service to break the law or to harass, harm or mislead anyone.

If you break these rules, we may limit, suspend or end your access as described in section 11.

6. Content and intellectual property

Our content

The practice questions, answer explanations, glossary entries, text, graphics, software, design and the Cairn name and logo belong to [Legal entity name] or the people who license them to us, and they are protected by copyright and other laws. As long as you follow these Terms, we give you a personal, limited, non-exclusive, non-transferable permission to use the Service and its content for your own study. We may withdraw that permission if you break these Terms. These Terms do not give you any other rights in our content.

Your information

You keep ownership of what you give us, such as your display name and profile choices. Your answers and practice history belong to you as well. You allow us to store, use and display that information as needed to run the Service for you, as described in our Privacy Policy.

Aggregated information

We may combine information about how the Service is used into aggregated, de-identified statistics that do not identify you, for example how many learners answered a particular question correctly. We may use those statistics to improve the Service, including to find and fix questions that are confusing or wrong.

7. Purchases and refunds

Full Practice for each exam is a separate one-time purchase. A purchase unlocks our practice tests and exercise sets for the exam it names; a combined purchase, where we offer one, unlocks our practice for every exam it names. A purchase does not unlock practice for other exams. We show the price and any applicable discount before you buy. Purchases are currently offered to US customers only. By providing a US state and ZIP code at checkout, you confirm that you are in the United States. There is no subscription or recurring charge.

[Legal entity name] is the seller. Stripe processes the payment for us; we do not store your full card number. You must accept these Terms and the refund policy at checkout before paying.

Refund policy

Refunds are offered only at our discretion, except where required by law. No refunds once you start a test or set unlocked by this purchase. Starting a free test or free exercise set does not use your purchase or trigger this restriction. We keep test and exercise start times so we can determine whether paid access has been used.

To request a discretionary refund before using paid access, sign in, open Support and choose “Refund request”. You can see an initial eligibility check before sending your request. An admin reviews the request, and any refund is issued manually. A request does not guarantee a refund. A full refund removes access to content unlocked by the purchase; a partial refund does not. You can still review your own completed work.

This policy does not limit any consumer rights that cannot be waived under applicable law.

8. Important disclaimers

No affiliation

SAT® is a trademark registered by the College Board, which is not affiliated with, and does not endorse, this site.

ACT® is a registered trademark of ACT Education Corp., which is not affiliated with, and does not endorse, this site. National Merit® is a registered trademark of the National Merit Scholarship Corporation.

No guarantee of results

Practice can help, but we cannot promise any particular outcome. We do not guarantee any test score, score increase, college admission, scholarship or award, including recognition in the National Merit Scholarship Program. Your results depend on many things that we do not control.

For educational use

The Service is a study aid. It is not a substitute for official test materials, your teachers or school counselors. Always check official sources for test dates, registration, rules and scoring. We work hard to make our questions and explanations accurate, but they may sometimes contain mistakes. If you spot one, please sign in and report it in Support.

The Service is provided “as is”

To the fullest extent the law allows, we provide the Service “as is” and “as available”, without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not promise that the Service will always be available, uninterrupted or free of errors, or that your practice history will never be lost. Some places do not allow certain warranties to be excluded, so some of these exclusions may not apply to you.

9. Limitation of liability

To the fullest extent the law allows, [Legal entity name] and its owners, employees and contractors will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, opportunity or goodwill, arising from or related to the Service or these Terms. This includes any claim based on a test score, an admission decision or a scholarship result.

To the fullest extent the law allows, our total liability for all claims arising from or related to the Service or these Terms is limited to the amount you paid us for the Service in the 12 months before the event that led to the claim.

Nothing in these Terms limits or excludes any liability that cannot be limited or excluded under the law that applies to you.

10. Responsibility for misuse

If you misuse the Service or break these Terms or the law, and that causes someone else to bring a claim against us, you agree to be responsible for the reasonable losses and costs that result, to the extent the law allows. This does not apply to anything we caused ourselves. We will let you know promptly about any such claim.

11. Ending your use of the Service

You may stop using the Service at any time. To close your account, use the “Delete account” control on your Account page or email us at privacy@example.com. Deletion is permanent: your sign-in account, your profile, support requests and all of your practice history are removed, and we cannot restore them.

We may suspend or end your access to the Service if you seriously or repeatedly break these Terms, if we need to in order to protect the Service, other users or the public, or if the law requires it. Where it is reasonable and allowed, we will tell you why. If we decide to shut down the Service as a whole, the notice and refund terms in section 4 apply.

Sections 6 (except the permission to use the Service), 8, 9, 10, 12, 13 and 15 continue to apply after your account is closed.

12. Governing law

These Terms are governed by the laws of [State of governing law] and the applicable laws of the United States, without regard to conflict-of-laws rules. If you live in a place whose consumer protection laws give you rights that cannot be waived by agreement, nothing in these Terms takes those rights away.

13. Resolving disagreements

If you have a concern about the Service, please sign in and contact us through Support. Most problems can be solved quickly that way, and we will try in good faith to resolve yours.

If we cannot resolve a dispute informally, it will be decided by the state or federal courts located in [State of governing law], unless the law that applies to you gives you the right to bring the claim somewhere else.

14. Changes to these Terms

We may update these Terms from time to time, for example when we add features or when the law changes. When we do, we will change the “Last updated” date at the top of this page. If we make a change that materially affects your rights, we will tell you in the Service or by email before the change takes effect, and we may ask you to accept the updated Terms before you continue using the Service. If you do not agree to the updated Terms, you can stop using the Service and delete your account.

15. Other legal terms

• These Terms, together with our Privacy Policy and any terms shown to you when you buy a paid feature, are the whole agreement between you and us about the Service.
• If any part of these Terms is found to be unenforceable, the rest of the Terms stay in effect.
• If we do not enforce a part of these Terms right away, we have not given up our right to enforce it later.
• You may not transfer your rights under these Terms to anyone else. We may transfer ours as part of a merger, acquisition or sale of all or part of our business, provided the Terms continue to protect you in the same way.
