How we handle your data and cookies
Last Updated: June 5, 2026
This notice explains what information Mathematical Magic collects when you visit mathematicalmagic.com, why we collect it, and what choices you have. We’re a small educational project about math tricks and the reasoning behind them, not a service that builds profiles or sells data — so this policy is short by design and tries to say plainly what actually happens.
What we collect
We keep data collection to the minimum a website needs to work and improve.
- Information you send us. If you email [email protected] — to flag a correction, suggest a trick, or ask how a method works — we receive your email address, your name if you include it, and whatever you write. If a contact form is added to the site in future, it collects only the fields shown on it.
- Information collected automatically. Like most websites, our hosting and analytics tools record basic technical details when a page loads: approximate location (usually country or city level), browser and device type, the pages viewed, and referring links. This is aggregate, not an attempt to identify you personally.
We do not run user accounts, take payments, or process financial information, so none of that data is collected here.
Why we use this information
We use what we collect to reply to your messages, to fix mistakes in our explainers, to understand which tricks and articles readers find useful, and to keep the site running and reasonably secure. We don’t sell your data, and we don’t share it except where a service we rely on (for example, our email inbox provider or hosting) processes it on our behalf to deliver the site.
Cookies and analytics
Mathematical Magic uses a small number of cookies and similar technologies. Some are needed for the site to function; others help us measure how content performs through analytics tools so we can decide what to write next. You can refuse or delete cookies in your browser settings at any time. Blocking them won’t stop you reading the site, though a few conveniences may not work as smoothly.
Content embedded from other places
Some articles may include material hosted elsewhere — for instance a video demonstrating a trick, or an embedded resource. When that content loads, the outside provider can set its own cookies and collect data about your visit exactly as if you had gone to their site directly. Their handling of that data is governed by their own privacy policies, not ours.
Links to other sites
We sometimes point to outside pages — a reference, a tool, or further reading. Once you leave mathematicalmagic.com we have no control over how those sites treat your information, so it’s worth checking their notices before sharing anything there.
The free handbook
Our free math magic handbook is offered as a direct PDF download. Downloading it does not, by itself, require you to give us any personal details. If we later offer the handbook by email, that step will be optional and clearly explained at the point you choose it.
Children’s privacy
Our material is written to be enjoyed by younger readers, including children, but the site is meant to be read, not to gather data from kids. We don’t knowingly collect personal information from children. If a child has sent us a message and a parent or guardian would like it removed, please write to [email protected] and we’ll delete it.
Your choices and your rights
Depending on where you live, you may have rights over the information we hold — to ask what we have, to request a copy, to have it corrected, or to ask us to delete it. Readers in regions such as the European Economic Area and India have such rights under local data-protection law. To make a request, email us and tell us what you’d like; we’ll respond within a reasonable time and may need to confirm your identity first.
How long we keep things
We keep messages only as long as they’re useful — for handling your query, completing a correction, or referring back to a conversation — and clear them out when they no longer serve a purpose. Aggregate analytics may be retained longer because it no longer identifies individual readers.
Security
We take sensible steps to protect the limited data we hold, but no website or method of transmission over the internet is completely secure, and we can’t promise absolute protection. We can promise to keep what we collect small, which is the best protection of all.
Changes to this notice
As the site grows — a newsletter, a contact form, new tools — this notice will be updated to match, with the revision date at the top changed accordingly. Continued use of the site after an update means the current version applies.
