Privacy Policy

Information we collect

• You can use all calculators without creating an account or providing personal information.
• If you contact us, we receive your name, email address, and message so we can reply.
• Basic technical data (such as browser type, device type, and pages visited) may be collected to operate and improve the site.
• Calculator inputs are processed locally in your browser and are never sent to our servers, stored, or sold. The only information we receive is what you voluntarily include in a contact message.

Cookies

We may use cookies or similar storage to remember preferences (such as dismissing a notice) and to understand aggregate usage. You can disable cookies anytime in your browser settings; the calculators will still work, but some preferences may not be remembered.

Analytics

We use Microsoft Clarity and Google Tag Manager to understand how visitors use the site. These services may set cookies and collect anonymized data such as pages visited, time on page, and scroll depth. No personally identifiable information is collected by Clarity or GTM beyond what you provide in a contact form.

Advertising

This site may display ads served by Google AdSense. AdSense may use cookies to personalize ads based on your visit to this and other sites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Your rights

• You may request deletion of any contact message data by emailing support@zencalcy.com.
