MathFlow (“we”, “us”, “the Website”) respects your privacy. This Privacy Policy describes what information we collect when you visit MathFlow, how we use it, and the choices available to you. By using the Website, you agree to the collection and use of information in accordance with this policy.

We collect limited information automatically when you visit the Website, and additional information only when you choose to provide it (for example, by contacting us).

Many MathFlow tools require you to enter text, numbers, or upload a file (such as a PDF) in order to generate a result. This input is used only to perform the requested calculation or conversion.

• Some tools process data entirely in your browser and never send it to our servers.
• Other tools may temporarily process files or text on our servers to generate a result.
• We do not permanently store the content of files or text you submit to a tool, and we do not review, sell, or use that content for any purpose beyond producing your requested result.

MathFlow uses cookies and similar tracking technologies to operate the Website, remember your preferences, and understand how visitors use our tools. This may include third-party analytics providers such as Google Analytics, and advertising partners if ads are displayed on the Website. You can control or disable cookies through your browser settings, though this may affect some site functionality.

We use the information we collect to:

• Operate, maintain, and improve MathFlow’s tools and pages
• Understand how visitors use the Website so we can improve it
• Monitor for security issues, abuse, or technical problems
• Respond to messages sent through our Contact page
• Comply with applicable legal obligations

We do not sell your personal information. We may share limited information with trusted third parties who help us operate the Website, such as hosting providers, analytics services, and advertising networks. These parties are only permitted to use the information to provide services to us and are bound by their own privacy obligations. We may also disclose information if required to do so by law.

We retain usage and technical data only for as long as necessary to fulfil the purposes described in this policy, such as analytics and security monitoring. Content submitted to tools (such as uploaded files or entered text) is not retained beyond the time needed to generate your result, unless a specific tool states otherwise.

If you are located in the European Economic Area, you have certain rights regarding your personal data under the General Data Protection Regulation (GDPR), including the right to:

• Access the personal data we hold about you
• Request correction of inaccurate data
• Request deletion of your data
• Object to or restrict certain processing
• Request a copy of your data in a portable format
• Lodge a complaint with a data protection authority

To exercise any of these rights, please contact us through our Contact page.

We take reasonable technical and organizational measures to protect the information we collect. However, no method of transmission over the internet or electronic storage is completely secure, and we cannot guarantee absolute security.

MathFlow is not directed at children under the age of 13 (or the applicable age of digital consent in your country), and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can take appropriate action.

MathFlow is operated from Spain. If you access the Website from outside Spain or the European Economic Area, your information may be transferred to, stored, and processed in a country different from your own. Where this occurs, we take steps to ensure appropriate safeguards are in place.

We may update this Privacy Policy from time to time to reflect changes to our practices or for legal reasons. Any changes will be posted on this page with an updated revision date. We encourage you to review this page periodically.
