romannumerals.io is a free, educational website. We do not collect, store, or sell any personal data.

What we collect

We collect no personal information. All converter and quiz functionality runs entirely in your browser — nothing you type is sent to our servers.

We use a single localStorage value (theme) to remember your dark/light mode preference. This is stored in your browser only and never transmitted.

This site loads no third-party scripts, fonts, or tracking pixels. All assets (fonts, icons) are self-hosted.
