Privacy
Short version: no accounts, no ads, no selling data. Your measurements stay in your browser.
What stays on your device
Each calculator remembers the numbers you last typed so you can come back to them. They are saved in your browser’s localStorage under keys starting with hc:. They never leave your device and we can’t see them.
The AI advisor and quote checker
If you choose to ask the advisor a question or paste a quote, that text (and a short summary of the calculator it came from) is sent to our server and on to an AI model through Vercel AI Gateway to generate the answer. We don’t store it or attach it to you. Don’t paste names, addresses or phone numbers from a quote.
Analytics
We use Ahrefs Web Analytics, a cookieless, privacy-friendly analytics tool, to count page views and see which calculators are useful. It doesn’t use cookies or build profiles of individual visitors.
