Privacy Policy
Information and payments
Muscle Math Mania does not request student information and does not store payment-card details. Digital purchases are processed by Lemon Squeezy, which handles checkout, payment, tax, receipt and file-delivery data under its own privacy terms. Paperback purchases, when available, are processed by Amazon.
The free sample form
What we collect. Your email address, the date and time you asked, and — if you arrived from a tagged link such as a social post — the campaign name from that link. That is everything. We do not ask for your name, your child's name, their age, their school, or any other detail, and we do not want them.
What we do with it. We email you the sample packet straight away, then two short notes over the following week about how the workbooks are built. After that we may occasionally write when a new workbook is released. Nothing else.
Where it is held. In a private Google Sheet and Gmail account belonging to Muscle Math Mania, covered by Google's own security and privacy terms. It is not shared with any mailing platform, advertising network, data broker or other third party. We do not sell, rent, trade or share the list with anyone, ever.
Getting off it. Every email carries a one-click unsubscribe link that works immediately and permanently. You can also reply to any email and ask, or use the support instructions.
How long we keep it. If you unsubscribe, your address is deleted within 30 days. Otherwise we keep it while the list is active; ask us to erase it at any time and we will.
This form is for adults. Please do not submit a child's email address. Muscle Math Mania is sold to parents, guardians and educators, and the free sample is intended for them.
Analytics
This site is prepared for privacy-conscious Google Analytics 4 measurement, but analytics is currently disabled and no measurement ID is configured. If it is enabled later, it would measure page views, broad device and traffic information, campaign parameters and outbound purchase-button clicks. It would not intentionally collect names, payment details or sensitive student data.
Security
Payment card details never reach us — Lemon Squeezy and Amazon handle those on their own systems. The accounts holding the sample list are protected by two-factor authentication. The site is served over HTTPS only. No customer data is stored on the website itself.
