We do not need your details
The calculators run entirely in your browser. You do not sign up, log in or hand over a name, email or address to get a result. We do not sell or rent personal information, because we do not collect it in the first place.
Your numbers stay yours.
Calculate My Reno is built to be useful without being nosy. The calculators work without an account, and we keep data collection to the minimum needed to run the site and keep it free. Here is exactly what that means in practice.
What is collected automatically
Like most sites, our analytics record basic technical data - rough location, device type, browser and which pages you viewed. We use Google Analytics. The data is aggregated to see which calculators are useful, not to identify you. You can opt out of Google Analytics with their browser add-on.
Advertising
This site is free because it shows ads through Google AdSense. Google and its partners may set cookies to measure performance and, with your consent, show more relevant ads - see Google's privacy policy. You can manage ad personalisation in your Google Ad Settings or opt out across many networks at aboutads.info and youronlinechoices.com. The full detail is in our cookie policy.
Your choices
Non-essential cookies stay off until you accept them in the consent banner, and you can change your mind any time by clearing site data. You can also block or delete cookies in your browser and use private browsing - none of this stops the calculators working. How we use cookies is set out in the cookie policy, and the ground rules for using the site are in the terms of service.
In short
No account, no selling your data, no tricks. We collect the basic technical and advertising data most free sites rely on, and you stay in control of it through your browser.
