Privacy Policy
The short version
Every calculator on this site runs entirely inside your browser. The numbers you type — home prices, incomes, loan balances, project dimensions — are never transmitted to us, never stored on a server, and never leave your device.
What we do not collect
- Any value you enter into a calculator
- Account details — there are no accounts
- Uploaded files, because nothing is uploaded
What is collected automatically
Our hosting provider keeps standard server logs: IP address, browser user-agent, requested page and timestamp. These are used to keep the site online and diagnose faults.
If analytics are enabled, they record aggregate page views and general traffic sources. Analytics never receive calculator inputs.
Cookies
The site itself sets no tracking cookies. A dark-mode preference may be stored locally in your browser; it never leaves your device and can be cleared at any time.
Third parties
Web fonts are served by Google Fonts, which receives your IP address as part of that request. Some pages may carry advertising or affiliate links; those partners maintain their own privacy policies, and we never pass them anything you typed into a calculator.
Your control
Because we hold no personal records, there is nothing for us to export or delete. Clearing your browser data removes any local preference this site has saved.
