Privacy Policy

Last updated: March 7, 2026

1. Introduction

HQ Calculator ("we", "us", or "our") operates the website hqcalculator.com. This Privacy Policy explains how we collect, use, and protect information when you visit our website. We are committed to protecting your privacy and complying with applicable data protection laws, including the European Union General Data Protection Regulation (GDPR).

2. Information We Collect

We collect minimal data to improve our service. We do not collect personal information such as names, email addresses, or phone numbers unless you voluntarily provide it through our feedback widget.

2.1 Analytics Data

We use Cloudflare Web Analytics, a privacy-first analytics service provided by Cloudflare, Inc. This service:

  • Does not use cookies or local storage
  • Does not track individual users across sites
  • Does not collect personally identifiable information (PII)
  • Collects only aggregate, anonymized data such as page views, referrers, browser type, country, and device type

For more information, see Cloudflare Web Analytics privacy documentation.

2.2 Calculations

All calculations are performed entirely in your browser (client-side). No calculation inputs or results are sent to our servers or any third party. Your data stays on your device.

2.3 Feedback Widget

Our optional feedback widget allows you to rate your experience. Feedback responses are anonymous and do not contain personally identifiable information.

3. Cookies

HQ Calculator does not set any first-party cookies. We do not use tracking cookies, advertising cookies, or any other type of cookie. Cloudflare Web Analytics operates without cookies. Cloudflare's infrastructure may set essential security cookies (e.g., __cf_bm) to protect against bots and malicious traffic. These are strictly necessary cookies and do not require consent under GDPR.

4. Third-Party Services

We use the following third-party services:

  • Cloudflare (Cloudflare, Inc., USA) — content delivery network (CDN), DNS, DDoS protection, and web analytics. Cloudflare processes traffic data to deliver and protect our website. Cloudflare Privacy Policy.
  • Google Fonts (Google LLC, USA) — web font delivery. When you load our pages, your browser connects to Google's servers to download fonts. Google may log your IP address. Google Privacy Policy.

5. Your Rights (GDPR)

If you are located in the European Economic Area (EEA), you have the following rights under GDPR:

  • Right of access — request a copy of data we hold about you
  • Right to rectification — request correction of inaccurate data
  • Right to erasure — request deletion of your data
  • Right to restrict processing — request limitation of data processing
  • Right to data portability — request transfer of your data
  • Right to object — object to processing of your data

Since we do not collect personally identifiable information, these rights are largely inapplicable. However, if you believe we hold any personal data about you, please contact us.

6. Data Retention

We do not store personal data. Cloudflare Web Analytics data is aggregated and anonymized, and is retained by Cloudflare in accordance with their data retention policies.

7. Children's Privacy

Our website is available to users of all ages. We do not knowingly collect personal information from anyone, including children under 16. Since our calculators operate entirely client-side and we do not collect personal data, no special provisions are required.

8. Changes to This 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 page periodically.
