Privacy Policy 🛡️

At calce.xyz, your privacy and data security are our highest priorities. Because our tools handle sensitive industrial formulas and personal health biometrics, we have designed our core architecture to be privacy-first.

1. Local Data Processing (Zero Tracking)

The vast majority of our calculators, including the DRI and RDA Nutrition tools, run entirely locally inside your web browser using JavaScript. When you input your age, weight, height, or industrial formulas, that data is processed instantly on your device. We do not transmit, save, or store your mathematical inputs or health data to any database.

2. Advertising and Google AdSense

To keep calce.xyz 100% free for all users, we use third-party advertising companies, including Google AdSense and other ad networks, to serve ads when you visit our website. These companies may use information about your visits to this and other websites in order to provide advertisements about goods and services of interest to you. This tracking is strictly for advertising purposes and does not include your personal calculator inputs.

• Google DART Cookie: Google, as a third-party vendor, uses cookies to serve ads on calce.xyz. Google's use of the DART cookie enables it to serve ads to our users based on their visit to our site and other sites on the Internet.
• Opting Out: Users may opt out of personalized advertising by visiting Google's Ads Settings or by visiting aboutads.info.

3. Information We Do Collect

We do not require accounts or logins. The only data we collect is standard, anonymized analytics (such as pages visited, browser type, and region) to help us improve site performance and fix bugs.

4. Cookies and Web Beacons

calce.xyz uses minimal essential cookies to remember basic preferences. Furthermore, our third-party advertising partners (like Google AdSense) use cookies and web beacons to measure the effectiveness of their campaigns and personalize advertising content. You can manage or disable cookies via your browser settings at any time without losing access to our calculators.

5. WhatsApp & External Sharing

Our tools may offer a "Share via WhatsApp" or native sharing button. Clicking these buttons simply uses your device's native sharing capabilities to forward a generated image or link. calce.xyz has no access to your contacts or messages.

6. Changes to This Policy

We may update this Privacy Policy occasionally. We encourage you to review this page periodically for any changes. Continued use of calce.xyz constitutes your agreement to the current policy.

If you have any questions regarding our advertising policies or data handling, you can contact the administration via our main domain channels.
