Your privacy is important to us

Last updated: January 2026

1. Overview

Zaculators ("we," "our," or "us") operates the zaculators.com website and mobile applications (collectively, the "Service"). This Privacy Policy explains our data practices and how we protect your information when you use our Service.

We are committed to protecting your privacy. Zaculators does not collect, store, or share your personal information. All calculations are performed on your device and are never sent to our servers.

2. Information We Don't Collect

Our calculators operate entirely in your browser. We do NOT collect:

• Personal information (names, emails, phone numbers)
• Financial information (income, account numbers, savings amounts)
• Health information (weight, height, medical conditions)
• Location data
• Browsing history or cookies for tracking
• Any data you enter into our calculators

3. How We Operate

All calculations happen directly in your browser using JavaScript. Your inputs:

• Are processed locally on your device only
• Are never transmitted to our servers
• Are not stored anywhere
• Are deleted when you close the page or refresh

4. Cookies and Tracking

We only use localStorage to save your dark mode preference (light or dark theme). This is stored only on your device and never transmitted to us.

Third parties (Google AdSense) may use cookies for advertising purposes. These are not under our control. You can control cookies in your browser settings.

5. Third-Party Services

Our website uses:

• Google AdSense: For displaying advertisements. Google may collect information about your browsing for ad targeting. See Google's Privacy Policy
• Google Analytics (optional): For understanding site traffic (if we add it). See Google Analytics Privacy

6. Your Rights

Since we don't collect personal data, you have nothing to request deletion of. However, you can:

• Clear your browser cache to remove any stored preferences
• Disable cookies in your browser settings
• Use incognito/private browsing mode
• Opt out of personalized ads through Google Ads Settings

7. Security

Because we don't collect or store your data, there's no database to breach. Your information stays on your device. However, like all websites, we use HTTPS encryption to protect the connection between your device and our servers.

8. Children's Privacy

Our Service does not knowingly collect information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately. Our calculators are appropriate for all ages and do not collect any personal information.

9. Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by updating the "Last updated" date at the top of this page. Your continued use of the Service after any changes constitutes your acceptance of the new Privacy Policy.
