This Privacy Policy explains how [MaThink LLC] ("MaThink," "we," "us," or "our") collects, uses, and shares information when you use our website and purchase worksheets. It applies to visitors, registered account holders, and their guardians.
MaThink's website and account system are directed at parents and guardians, not children. We do not knowingly collect personal information directly from children under 13. Any student name or grade-level information in an account is entered by the parent or guardian who controls that account, for the purpose of personalizing worksheets and order history — not collected through direct interaction with a child.
If you believe a child has provided us with personal information directly, please contact us so we can review and, if appropriate, delete it. [This section should be reviewed against COPPA (Children's Online Privacy Protection Act) requirements by an attorney before launch, particularly if any future feature — such as a student-facing login or app — collects information directly from a child.]
We do not sell your personal information. We share information only as follows:
We use cookies and similar technologies to keep you logged in, remember your language preference (English/Korean), and understand how visitors use our site. You can control cookies through your browser settings; disabling them may limit some site features (such as staying logged in).
We retain account and order information for as long as your account is active and as needed to comply with legal, tax, and accounting obligations. You may request deletion of your account as described below, subject to records we are required to keep by law.
Depending on where you live, you may have the right to access, correct, export, or delete your personal information, and to opt out of marketing emails at any time (via the unsubscribe link or by contacting us). California residents may have additional rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect and to request deletion; we do not sell personal information as defined by the CCPA. [Confirm applicable state privacy laws — e.g., CCPA, and any others relevant to where you do business — with counsel.]
We use industry-standard safeguards (such as encryption in transit, hashed passwords, and access controls) to protect your information. No method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above, and where appropriate, we will notify you directly.
