Privacy policy
Last updated: September 28, 2026
This policy explains what information MyDeckMath collects, how it is used and what choices you have. The short version: the calculators run entirely in your browser, and we don't require an account.
1. Information we collect
The numbers you enter into the calculators are processed in your browser and are not sent to our servers. If you contact us through the contact form, we receive your name, email address and message so we can reply.
2. Cookies and analytics
The site does not set advertising cookies. If we add privacy-respecting analytics in the future, this policy will be updated before they go live.
3. Third-party services
Contact form submissions are processed by Web3Forms, which receives the data you submit in order to deliver it to us. Static assets are served through our hosting provider's CDN. We don't sell or share your information with advertisers or data brokers.
4. Data retention
Contact messages are kept only as long as needed to handle your request and normal business correspondence, then deleted.
5. Your rights
You can ask what personal data we hold about you, request correction or deletion, or object to its use. Email us through thecontact page and we'll respond within a reasonable period.
6. Children's privacy
The site is intended for general audiences and is not directed at children under 13. We do not knowingly collect personal information from children.
7. Changes to this policy
We may update this policy occasionally. The "last updated" date at the top reflects the latest revision. Continued use of the site after changes means you accept the revised policy.
