Privacy Policy

1. Our Core Privacy Philosophy

At Calculators99, your privacy is fundamental to our architecture. Unlike traditional financial or medical websites, our calculators execute computations client-side directly in your web browser using JavaScript. When you enter a loan amount, income figure, body measurement, or date of birth into our calculators, that data is processed exclusively on your local device and is never transmitted to our servers or stored in any database.

2. Information We Do Not Collect

We strictly do not collect:

• Personal calculation parameters (e.g., mortgage amounts, salaries, weights, gestational dates, generated passwords).
• User accounts, profiles, passwords, or payment card numbers (our services are completely free and require no registration).
• Sensitive biometric, demographic, or financial history.

3. Technical Server Logs

Like virtually all web hosts, our web servers record standard HTTP request logs (including IP address, browser user-agent, referring page, and timestamp) solely for operational reliability, DDoS prevention, and diagnosing server performance. These logs are purged periodically.

4. Cookies and Currency Preferences

Calculators99 does not require an account and does not store the values you enter in the calculators. The only data kept in your browser is your currency preference (a lightweight cookie named calc99_currency), which you can clear in your browser settings at any time. When you first visit without a saved preference, your country is approximated once from your IP address to suggest the appropriate national currency format; the IP address is not stored or logged for this purpose. We do not sell, rent, or trade your data to third parties.

5. Self-Hosted Assets & Zero External CDNs

To guarantee user privacy, security, and high reliability, all fonts, style sheets, and JavaScript libraries (Bootstrap, Bootstrap Icons, and Chart.js) are hosted 100% locally on our servers. No requests are sent to external third-party Content Delivery Networks (CDNs) when you browse Calculators99.

6. Children's Privacy

Calculators99 provides general educational and calculation tools accessible to all audiences. We do not knowingly solicit, collect, or store any personal information from children or any other visitors.

7. Changes to This Policy

We may update this Privacy Policy from time to time. The latest version is always available on this page, with the date it was last updated.
