Privacy Policy

1. Data We Collect

None of your personal data. xCalculator does not collect, store, or transmit any personally identifiable information (PII). Every calculation you perform — whether it's your BMI, calorie intake, mortgage payment, or tax estimate — is computed entirely within your browser. No values are ever sent to our servers.

We do not require account registration, email addresses, names, or any other identifying information to use any feature of this site.

2. Cookies

xCalculator uses no tracking cookies and no advertising cookies. We may use strictly necessary functional cookies (such as those set by Cloudflare for security and performance) that do not identify you personally.

We do not use cookies for cross-site tracking, retargeting, or behavioral advertising.

3. Third-Party Services

We use Cloudflare to deliver our website via their global CDN network. Cloudflare may process your IP address and request metadata as part of normal network operation and DDoS protection. This is governed by Cloudflare's Privacy Policy.

We do not use Google Analytics, Facebook Pixel, or any other third-party advertising or tracking scripts.

4. Analytics

We use Cloudflare Web Analytics to understand how our site is used in aggregate (e.g., page view counts, popular calculators). Cloudflare Web Analytics is privacy-preserving by design — it does not use cookies, does not fingerprint users, and does not collect personally identifiable information. You cannot be identified from this data.

5. Children's Privacy

xCalculator is suitable for general audiences. Because we collect no personal data whatsoever, we have no special procedures for children's data — there is simply nothing to collect.

6. Changes to This Policy

If we ever change our privacy practices in a meaningful way, we'll update this page with a new effective date. Our commitment to not collecting personal data is foundational to xCalculator, and we do not plan to change it.
