Privacy policy

Draft — to be reviewed by owner. This policy describes the site as currently built and has not yet had legal review.

Summary

• You do not need an account to use any tool.
• We do not sell personal data.
• Calculator inputs are sent to our server only to compute the result and are not stored.

What we collect

Like most websites, our servers record basic technical information (such as IP address, browser type, the page requested and the time) in logs used for security, rate limiting and troubleshooting. These logs are kept for a limited period.

Your streak, badges and game scores are stored in your own browser's local storage. They are not sent to us.

Cookies

Public pages do not set tracking cookies. The admin area uses a single secure session cookie for signed-in staff. If we add analytics or advertising in future, this policy will be updated and, where required, we will ask for consent first.

Third-party data providers

Data such as exchange rates and weather is fetched by our server from the providers listed on the data sources page. Your browser does not contact those providers when you view our pages, except when you follow a link to them.
