Visits
Page views are counted with Umami, an open-source analytics tool we host ourselves on our own server: its script loads from analytics.answermend.com, the only address outside this site that the pages contact. It records the page, the referring site, browser, device type and country. It sets no cookies and does not store your IP address.
Numbers you type
No calculator is live yet. The calculators are being built to work out results in your browser. When each one opens, this page will say what, if anything, leaves your device and how long any copy is kept.
Hosting
The site is hosted by Hostinger, whose servers keep standard access logs (IP address, time, page requested) for security and running the service. The pages use your device’s own fonts; nothing is loaded from a font service.
Light or dark theme
If you use the light/dark switch, your choice is saved in your own browser (local storage, key "ts-theme") so the next page opens the same way. It is not a cookie and it is never sent to us; clearing the site data in your browser removes it. Nothing else is stored in your browser by this site today.
