Privacy Policy

1. Information We Collect

Information you provide

Our calculators run entirely in your browser. Numbers and values you enter into any calculator are never sent to our servers — all calculations happen locally on your device.

Automatically collected information

When you visit our site, we may automatically collect standard web log data including your IP address, browser type, operating system, referring URLs, and pages visited. This data is used solely for analytics and improving site performance.

Cookies and local storage

We use browser local storage to remember your language preference and theme settings between visits. We do not use tracking cookies for advertising purposes.

2. How We Use Your Information

We use the information we collect to:

• Operate and improve our calculator tools and website
• Understand how visitors use the site through aggregated analytics
• Remember your preferences (language, theme) between sessions
• Diagnose technical issues and ensure site security

We do not sell, rent, or share your personal information with third parties for marketing purposes.

3. Third-Party Services

We may use third-party analytics services (such as Google Analytics) to understand site usage patterns. These services may collect anonymized usage data subject to their own privacy policies. We do not share personally identifiable information with these services.

We use Google Fonts for typography. When a page loads, your browser may make a request to Google's servers to retrieve font files. Please review Google's privacy policy for details on how they handle this data.

4. Data Security

We implement reasonable technical measures to protect our website from unauthorized access. Since calculator inputs are processed entirely in your browser and never transmitted to our servers, your calculation data is not at risk of a server-side data breach.

5. Children's Privacy

Our website is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.

6. Your Rights

Depending on your location, you may have rights regarding your personal data, including the right to access, correct, or delete any personal information we hold about you. To exercise these rights, please contact us using the details below.

7. Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will update the "Last updated" date at the top of this page. We encourage you to review this policy periodically.
