Privacy Policy
Last Updated 2026
At UnitFig, we are committed to protecting your privacy. This Privacy Policy explains how we handle your data when you visit our website and use our free unit converters and math worksheets.
Children's Privacy — Zero Data Collection
UnitFig is safe for classroom and family use because we collect no personal information from anyone, including children. Our converters and worksheets run entirely in your browser:
- No account, name, email, or password is ever requested.
- Values you type and problems generated stay on your device — they are never uploaded, stored, or shared.
- We do not target children with advertising, and we do not build profiles of any visitor.
- We align with the U.S. Children's Online Privacy Protection Act (COPPA) by design: there is simply no personal data to collect or disclose.
Teachers and parents can use UnitFig with students without a signup wall or any data-collection concern.
Information We Collect
Aggregated, anonymized usage data: Like most websites, we may collect high-level, non-identifying information to understand how the site is used, including:
- Browser type and version
- Operating system
- Device type (desktop, tablet, mobile)
- Pages visited (aggregated counts)
- Referrer URL (if applicable)
- IP address (anonymized)
Cookies: We use essential cookies to make the site work. Any analytics cookies are privacy-respecting and anonymized; you can control cookie settings in your browser.
How We Use Information
- To provide and maintain our service
- To understand aggregated, anonymous usage patterns
- To improve the website and user experience
- To detect and prevent abuse
Data Retention
Any anonymized usage data is retained for at most 26 months. We do not personally identify visitors and we do not sell personal information — in fact, we hold no personal information to sell.
Your Rights
Because we collect no personal data, there is nothing to access or delete. You may still contact us with any privacy question:
- Request information about our practices
- Opt out of analytics cookies via your browser settings
- Lodge a complaint with a data protection authority

If you send a message via our contact form, the name, email and message you submit are transmitted to and stored by Web3Forms (web3forms.com) solely to receive and respond to your inquiry.
