Last updated: September 22, 2026 (draft)
These Terms of Service ("Terms") govern your access to and use of the MaThink website, including any purchase of worksheets, account registration, or use of related services (collectively, the "Service"), operated by [MaThink LLC] ("MaThink," "we," "us," or "our"). By creating an account, placing an order, or otherwise using the Service, you agree to be bound by these Terms. If you do not agree, please do not use the Service.
MaThink sells leveled math worksheets (Levels L0 through L13) as secure digital PDF files, delivered by email for you to view and print at home. Worksheets are organized by level and sold individually or as level sets. Sample pages are available for preview before purchase.
You must be at least 18 years old, or the age of majority in your state, to create an account and make a purchase. Accounts are intended for use by a parent or legal guardian on behalf of a student. Any student information you provide (such as a first name) is submitted by you, the account holder, to personalize your order and worksheets — not collected by us directly from a child. See our Privacy Policy for details.
You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. Notify us promptly of any unauthorized use.
All prices are listed in U.S. dollars and are subject to change without notice; the price shown at checkout is the price you will be charged. Payments are processed by our third-party payment processor (currently planned: Stripe). We do not store your full card number on our servers. If you choose to save a payment method for faster checkout, it is tokenized and stored by our payment processor in accordance with PCI-DSS standards.
When you purchase a worksheet or worksheet set, we grant you a limited, non-exclusive, non-transferable license to use that worksheet for personal, non-commercial, single-household educational use only. You may print copies for the student(s) associated with your account.
You may not:
Worksheets may be watermarked with account or order information to discourage unauthorized redistribution.
Worksheets are delivered digitally: after checkout, you'll receive a secure link to view and print your worksheets at home. Each order includes a limited reprint window (currently 30 days from the date of purchase, subject to change at our discretion) during which you may view and print a purchased worksheet as many times as you like. Once the reprint window expires, access may no longer be available; contact us if you have questions about a specific order.
Because MaThink worksheets are digital files that you can access and print immediately after purchase, refund requests are handled differently than for a physical product. As a general rule, and consistent with standard practice for digital goods and instant-access downloads: an order that has not yet been opened or accessed may be eligible for a refund at our discretion; once any part of an order has been opened or accessed through our secure viewer, the order is generally no longer eligible for a refund. This reflects the fact that, once a digital worksheet has been made available to you in a usable, printable form, it cannot meaningfully be "returned."
We may make exceptions to the above — including for a duplicate charge, a billing error, a defective or corrupted file, or a technical problem that prevented you from receiving what you paid for — reviewed on a case-by-case basis. To request a refund or report a problem with an order, contact us at support@mathink.us with your order number. We may review your account's order and access history as part of that review. See our Privacy Policy for more on the information we keep about an order.
Refunds, where approved, are issued to the original payment method and may take several business days to appear on your statement, depending on your bank or card issuer.
You agree not to misuse the Service, including by: attempting to gain unauthorized access to any account or system; interfering with the normal operation of the Service; uploading malicious code; or using the Service for any unlawful purpose.
All worksheet content, curriculum design, the MaThink name, logo, mascot characters, and website content are the property of MaThink or its licensors and are protected by copyright and trademark law. Nothing in these Terms transfers ownership of any intellectual property to you beyond the limited license described in Section 5.
The Service may use third-party providers to operate, including payment processing (e.g., Stripe), authentication (e.g., Google Sign-In and an identity platform such as Firebase Authentication), cloud storage/hosting, and email delivery. Your use of those features is also subject to the applicable third party's terms and privacy policy.
The Service and all worksheets are provided "as is" and "as available" without warranties of any kind, express or implied, including implied warranties of merchantability, fitness for a particular purpose, or non-infringement. We do not guarantee any specific educational outcome from using our worksheets.
To the maximum extent permitted by law, MaThink shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of data, arising from your use of the Service. Our total liability for any claim relating to the Service shall not exceed the amount you paid to us in the 12 months preceding the claim.
You agree to indemnify and hold MaThink harmless from any claims, damages, or expenses (including reasonable attorneys' fees) arising from your violation of these Terms or misuse of the Service.
We may suspend or terminate your account at any time for violation of these Terms, including unauthorized redistribution of worksheets. You may close your account at any time by contacting us.
These Terms are governed by the laws of the State of [State], without regard to conflict-of-law principles, unless otherwise required by applicable consumer protection law in your jurisdiction. [Add arbitration/dispute-resolution clause here if desired, after attorney review.]
We may update these Terms from time to time. If we make material changes, we will update the "Last updated" date above and, where appropriate, notify you by email or through the Service. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
