This policy explains how www.lanhometech.com uses cookies and similar technologies.
What are cookies?
Cookies are small text files a site stores in your browser. Local storage is a related technology that keeps data on your device. We use both, sparingly.
How we use them
- Essential / functional: we use local storage to remember your recent calculations and whether you've dismissed the cookie notice. This data stays on your device.
- Analytics: Google Analytics sets cookies to measure page usage and performance so we can improve the tools.
- Advertising: if ads are shown, partners such as Google AdSense may set cookies to display and measure relevant ads.
Managing cookies
You can delete or block cookies in your browser settings. Most browsers let you refuse cookies or alert you when one is set. Blocking some cookies may affect analytics and ads but won't stop the calculators from working. To manage personalized advertising, use Google's Ads Settings and industry opt-out tools.
Clearing your saved calculations
Because your results live in your browser's local storage, clearing your browsing data will remove them. Nothing is stored on our servers.
For more on how we handle data, see our Privacy Policy.
