Privacy Policy
Last updated: January 2026
Information We Collect
mathcheck is designed to work without collecting personal information. You do not need to create an account or provide any personal details to use our tools. We may collect anonymous usage data (such as page views and general device type) to improve our service.
How We Use Information
Any anonymous data we collect is used solely to understand how our tools are used and to improve the experience. We do not sell, rent, or share any data with third parties for marketing purposes.
Cookies
mathcheck uses only essential cookies required for basic site functionality. We do not use tracking cookies or third-party advertising cookies.
Third-Party Services
We may use third-party analytics services that collect anonymous, aggregated data. These services are governed by their own privacy policies.
Children's Privacy
mathcheck is designed for use by students of all ages. We do not knowingly collect personal information from children under 13. Because our tools do not require accounts or personal data, there is no mechanism for such collection. If you believe we have inadvertently collected personal information from a child, please contact us and we will promptly delete it.
Data Retention
Your calculations and conversions are processed entirely in your browser and are not stored on our servers. Anonymous analytics data is retained for up to 12 months.
Your Rights
Since we do not collect personal data, there is generally no personal information to access, correct, or delete. If you have concerns, please contact us.
Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated revision date.
