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 are processed by Amazon under Amazon’s own privacy policy; we never see the buyer’s name, address or card.
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.
The contact form
What we collect. The email address you give us, your name if you choose to add it, the topic you pick and your message. Why. Only to read and answer your message. Where. Submissions are received by our website host, Netlify, and forwarded to our private inbox. They are not added to the sample mailing list, and they are not shared, sold or used for marketing. Ask us and we will delete them.
Free sample downloads
The per-book samples on the Workbooks page are ordinary file downloads. They need no email address and we do not record who downloads them.
Fonts and third parties
This website serves its own fonts and images from its own domain. Pages do not load code or fonts from third-party servers. Clicking a buy button takes you to Amazon or Lemon Squeezy, whose own privacy policies apply from that point.
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. Access to the accounts holding the sample list is limited to Muscle Math Mania. The site is served over HTTPS only. No customer data is stored on the website itself.
