Privacy Policy

Last updated: January 15, 2025

Welcome to Royal Calc. Your privacy is important to us. This Privacy Policy explains how we handle your information when you use our free online calculators.

1. Information We Collect

Royal Calc is designed to be privacy-first. We collect minimal information:

  • Data you enter: Numbers and values you input for calculations.
  • Usage data: Anonymous information about which calculators are used and how often (via Google Analytics).
  • IP addresses: Temporarily logged for security purposes (server logs).

2. How We Use Your Data

Your input data is used only for the specific operation you request:

  • Real-time processing: Calculations are performed instantly in your browser.
  • No permanent storage: We do not store, archive, or backup any user data.
  • No access to content: We do not access, view, or analyze your calculation data beyond the requested operation.

3. Data Security

We take data security seriously:

  • Encryption: All data transfers are protected with 256-bit SSL encryption.
  • Secure servers: Data is processed on secure servers with restricted access.
  • No storage: Data is processed in real-time and not stored.
  • No third-party sharing: We never share your data with third parties.

4. Cookies and Tracking

Royal Calc uses cookies and similar technologies to improve your experience:

  • Essential cookies: Required for basic site functionality (e.g., remembering your preferences).
  • Google Analytics: We use Google Analytics to understand how visitors use our site. This helps us improve our tools. Google Analytics collects anonymous data such as pages visited, time spent, and referral sources.
  • No tracking across sites: We do not use cross-site tracking or retargeting ads.

You can disable cookies in your browser settings, but some features of our tools may not function properly.

5. Third-Party Services

We use the following third-party services:

  • Google Analytics: For anonymous usage analytics. Google's Privacy Policy
  • Calculation libraries: We use open-source libraries that run on our own servers. No data is sent to third parties for processing.
  • Hosting provider: Data is processed on our secure servers. Our hosting provider does not access or store your data beyond the processing window.

6. Data Retention

  • Input data: Processed in real-time and not stored.
  • Server logs: IP addresses and access logs are retained for 30 days for security purposes, then automatically deleted.
  • Analytics data: Google Analytics retains anonymous data according to their policies (default: 26 months, then auto-deleted).
  • No user accounts: Since we don't require signup, we don't store any personal information long-term.

7. Children's Privacy

Royal Calc is a general audience service. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us, and we will take steps to delete such information.

8. Your Rights

Depending on your location, you may have certain rights regarding your data:

  • Right to access: Request a copy of data we hold about you.
  • Right to deletion: Request deletion of your data.
  • Right to object: Opt-out of analytics tracking.
  • Right to rectification: Correct inaccurate data.

Since we don't store input data or require signup, most of these rights apply only to server logs and analytics data. To exercise these rights, contact us.

9. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. We encourage you to review this policy periodically.
