Math Tools ("we," "us," or "our") respects your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website (the "Service"). Please read this Privacy Policy carefully. By using the Service, you consent to the practices described herein.
Information Collected Automatically: When you access the Service, certain information may be collected automatically, including your IP address, browser type and version, operating system, referring URLs, pages viewed, time spent on pages, and the date and time of your visit. This information is collected via server logs and analytics tools.
Cookies and Tracking Technologies: We and our third-party partners (including advertising partners such as Google AdSense) may use cookies, web beacons, pixels, and similar tracking technologies to collect information about your browsing activity. Cookies are small data files stored on your device. You can control cookies through your browser settings, but disabling cookies may affect the functionality of the Service.
Information You Provide: The Service does not require you to create an account or provide personal information to use its mathematical tools. All calculations are performed client-side in your browser. We do not transmit, store, or process the numbers or expressions you input into our calculators on our servers. The study tools (Flashcards and Quiz Maker) store your created content exclusively in your browser's local storage on your device. This data never leaves your device and is not accessible to us or any third party. Clearing your browser data will permanently delete this locally stored content. The grammar checker processes all text entirely within your browser — your essays, documents, and written content are never sent to or stored on any server. Your writing remains private on your device at all times.
We use the information we collect to: operate, maintain, and improve the Service; understand how users interact with the Service to improve user experience; comply with legal obligations; detect and prevent fraud or abuse; and serve relevant advertisements via third-party ad networks.
We may use third-party advertising companies, including Google AdSense, to serve advertisements on the Service. These companies may use cookies and similar technologies to collect information about your visits to this and other websites in order to provide advertisements about goods and services that may interest you.
Google's use of advertising cookies enables it and its partners to serve ads based on your visit to this site and/or other sites on the Internet. You may opt out of personalized advertising by visiting Google Ads Settings. You may also visit www.aboutads.info/choices to opt out of third-party vendor cookies for personalized advertising.
We may use Google Analytics to help us understand how visitors use the Service. Google Analytics collects information such as how often users visit the site, what pages they visit, and what other sites they visited prior to coming to the Service. We use the information we get from Google Analytics to improve the Service. Google Analytics collects only the IP address assigned to you on the date you visit the Service, rather than your name or other identifying information. For more information on how Google uses data, visit Google's Privacy & Terms.
We retain automatically collected information (such as server logs) for a reasonable period of time for analytics and security purposes. We do not retain any of the mathematical data you input into the Service's tools, as all computations are performed entirely within your browser.
We implement reasonable administrative, technical, and physical security measures to protect the information we collect. However, no method of transmission over the Internet or method of electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee its absolute security.
The Service is designed to be used by students of various ages as an educational tool. We do not knowingly collect personal information from children under the age of 13 (or the applicable age in your jurisdiction under laws such as COPPA). If you are a parent or guardian and believe we have collected personal information from a child, please contact us immediately and we will take steps to delete such information.
Some browsers include a "Do Not Track" (DNT) feature that signals to websites that you do not want to have your online activity tracked. There is currently no uniform standard for how companies should respond to DNT signals. We currently do not respond to DNT browser signals, but we encourage you to review the privacy settings in your browser.
The Service may contain links to third-party websites or services that are not operated by us. We have no control over, and assume no responsibility for, the content, privacy policies, or practices of any third-party websites or services. We encourage you to review the privacy policy of every site you visit.
Depending on your jurisdiction, you may have the right to: access the personal information we hold about you; request correction of inaccurate information; request deletion of your information; object to or restrict certain processing of your information; and withdraw consent where processing is based on consent. To exercise any of these rights, please contact us using the information below.
If you are a California resident, you may have additional rights under the California Consumer Privacy Act (CCPA), including the right to know what personal information we collect, the right to request deletion, and the right to opt out of the sale of personal information. We do not sell personal information. To make a request under the CCPA, please contact us.
If you are located in the European Economic Area (EEA), you may have additional rights under the General Data Protection Regulation (GDPR), including the right to access, rectification, erasure, restriction, data portability, and the right to lodge a complaint with a supervisory authority. Our legal basis for processing data is legitimate interest (operating and improving the Service) and consent (for cookies and personalized advertising).
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. We encourage you to review this Privacy Policy periodically for any changes. Your continued use of the Service after any modifications to this Privacy Policy constitutes your acceptance of those changes.
If you have any questions or concerns about this Privacy Policy, please contact us through our website's contact form or by opening an issue on our GitHub repository.
