Short version: we don't collect your personal data, and the calculators run entirely on your device. Here's the detail.
What the calculators do with your numbers
Nothing leaves your browser. Every calculation — your room dimensions, your prices, your results — happens locally in JavaScript on your device. We never receive it, store it, or transmit it anywhere. There are no accounts and no logins on Renovate Cafe.
Analytics
We use Cloudflare's built-in, privacy-respecting analytics to understand broad traffic trends (which pages are popular, roughly where visitors come from). It does not use cookies and does not collect personally identifiable information. We do not run Google Analytics or any tracking pixels.
Advertising
Renovate Cafe displays ads to keep the site free. When advertising is active, ads may be served by Google AdSense or a similar network. These networks may use cookies or similar technologies to show relevant ads and measure performance. You can review and control ad personalization through Google's Ads Settings and opt out of personalized advertising at aboutads.info.
If you're in a region covered by GDPR or CCPA, our ad partners provide the required consent controls; you'll see a consent prompt where the law requires one.
Affiliate links & advertising disclosure
Some links on Renovate Cafe are affiliate links. As an Amazon Associate, and through other affiliate programs, we may earn a commission from qualifying purchases made through those links — at no extra cost to you. We only link to tools and materials we believe are genuinely worth owning. Affiliate relationships never change the math in our calculators or the substance of our guides.
Calculator accuracy
Our calculators provide planning estimates based on standard industry references. They are not a substitute for professional judgment. For structural, electrical, plumbing, or permitted work — and any job where being wrong is dangerous or expensive — confirm your quantities and local building code with a licensed professional or your supplier. See our full disclaimer for the details on accuracy, safety, and liability.
Children's privacy
Renovate Cafe is intended for a general, adult, do-it-yourself audience and is not directed at children under 13. We do not knowingly collect any information from children.
Changes & contact
We may update this policy as the site evolves; the date below reflects the current version. Questions about privacy or anything else? Email us.
