This Cookie Policy explains what cookies are, how Kalkfy (kalkfy.com) uses them, and how you can manage your preferences.
What Are Cookies
Cookies are small text files that websites place on your device (computer, tablet, or phone) through your browser. They serve various purposes, from remembering your preferences to helping site owners understand how visitors interact with their pages.
Cookies are standard across nearly all websites and, on their own, do not identify you personally.

What Happens If You Disable Cookies
Disabling cookies will not prevent you from using our calculators, but it may affect other parts of your experience:
- Analytics cookies disabled – Your visit will not be counted in our traffic data. No impact on your experience.
- Advertising cookies disabled – Ads will still appear, but they may be less relevant to your interests. Google may show generic ads instead of targeted ones.
- All cookies disabled – The site will still work, but your cookie consent preference will not be remembered, and you may see the cookie notice on every visit.
