Privacy policy
Last updated: November 12, 2026. We keep data collection to a minimum.
Calculator inputs
The numbers you type into our calculators are processed in your own browser. We do not store them on our servers and we do not need an account to use any tool.
Preferences saved on your device
Your chosen language, number format, currency and dark-mode setting are saved in your browser's local storage so the site remembers them. You can clear them at any time through your browser settings.
Analytics and server logs
Like most websites, our hosting provider may record standard technical information such as IP address, browser type and pages visited to keep the service secure and working. If we use an analytics service such as Google Analytics, it collects anonymous usage statistics to help us improve the site, governed by that provider's own privacy policy.
Links to other websites
We link to official sources such as government agencies. Their privacy practices are their own.
Children
The site is intended for a general audience and does not knowingly collect personal information from children.
Changes
We may update this policy and will change the date above when we do.
