Legal Bases for Processing
Where laws such as the General Data Protection Regulation apply, information may be processed under one or more of the following legal bases:
- Your consent
- Performance of a contract or response to your request
- Compliance with a legal obligation
- Our legitimate interests in operating, securing, analyzing, and improving the Site

When processing is based on consent, you may withdraw that consent at any time, subject to applicable law.
Data Retention
We retain personal information only for as long as reasonably necessary for the purpose for which it was collected, including responding to requests, maintaining security, resolving disputes, enforcing agreements, and meeting legal obligations.
Retention periods may vary depending on the type of information and the service involved.
Information stored locally in your browser remains until it expires, is replaced, or is deleted through the Site or your browser settings.
Third-party providers may apply their own retention periods as described in their privacy policies.
Data Security
We use reasonable administrative and technical measures intended to protect the Site and information processed through it.
However, no website, transmission method, or electronic storage system can be guaranteed to be completely secure. You use the Site and submit information at your own risk.
International Data Transfers
OutputMath is available to visitors in multiple countries.
Information may be processed in countries other than the country in which you live. These countries may have different data protection laws.
When required, service providers are expected to use legally recognized safeguards for international data transfers.

Depending on where you live, you may have rights concerning your personal information, including the right to:
- Request access to personal information
- Request correction of inaccurate information
- Request deletion of certain information
- Object to or restrict certain processing

We will not discriminate against you for exercising a privacy right provided by applicable law.
Children’s Privacy
The Site is intended for a general audience and is not directed to children under 13 years of age.
We do not knowingly collect personal information from children under 13. If you believe that a child has provided personal information through the Site, please contact us so that we can review and, where appropriate, delete it.
Visitors in jurisdictions with a higher minimum age for valid consent should use the Site only with the involvement of a parent or legal guardian when required.
Do Not Track Signals
Some browsers transmit “Do Not Track” signals.
Because there is not a universally accepted standard for responding to all such signals, the Site may not respond to them automatically. We will honor legally required browser-based opt-out signals when applicable and technically supported.

We may update this Privacy Policy to reflect changes to the Site, service providers, legal requirements, or privacy practices.
The updated version will be posted on this page with a revised “Last updated” date. Material changes may also be communicated through an additional notice where appropriate.
