Privacy Policy

This Privacy Policy describes how CalcModern ("we", "us", "our") collects, uses and protects information when you visit calcmodern.com (the "Site"). By using the Site you agree to the practices described below.

1. Information We Collect

CalcModern is a static website. The calculators run entirely in your browser and we do not store the values you enter. We do not require registration or login.

We may collect the following non-personal information automatically:

• Log data: Your IP address, browser type, operating system, referring URL, pages visited and timestamps — collected by our hosting provider for security and analytics.
• Aggregated analytics: Anonymous page view counts and traffic sources to help us understand which calculators are most useful.

2. Cookies

We use a minimal number of first-party cookies for essential site functionality (e.g., remembering your cookie consent preference). Third-party services described below may set their own cookies.

Types of cookies used:

• Essential cookies: Required for the site to function properly (e.g., consent preferences).
• Analytics cookies: Help us understand traffic patterns (anonymous, aggregated data only).
• Advertising cookies: Set by Google AdSense and its partners to serve relevant ads.

You can control cookies through your browser settings. Disabling cookies may affect the functionality of some third-party features.

3. Advertising (Google AdSense)

This site displays advertisements served by Google AdSense. Google and its certified ad networks may use cookies, web beacons and similar technologies to serve ads based on your prior visits to this Site and other websites on the Internet.

• Google's use of advertising cookies enables it and its partners to serve ads to users based on their visit to this Site and/or other sites on the Internet.
• You may opt out of personalized advertising by visiting Google Ads Settings.
• You can also opt out of a third-party vendor's use of cookies for personalized advertising by visiting www.aboutads.info/choices.
• Users in the European Economic Area can manage consent at www.youronlinechoices.eu.

4. How We Use Information

The limited non-personal information we collect is used to:

• Maintain and improve the Site's performance and security.
• Understand which calculators are most popular so we can prioritize improvements.
• Detect and prevent abuse or unauthorized access.
• Comply with legal obligations.

5. Data Sharing

We do not sell, trade, or rent your personal information to third parties. Information may be shared only with:

• Hosting providers: For serving the Site and maintaining server logs.
• Google AdSense: For displaying advertisements (see Section 3).
• Law enforcement: If required by law, subpoena or court order.

6. Children's Privacy (COPPA)

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

7. Your Rights (GDPR / CCPA / Other)

Depending on your jurisdiction, you may have the following rights:

• Right of access: Request a copy of the data we hold about you.
• Right to rectification: Request correction of inaccurate data.
• Right to erasure: Request deletion of your data ("right to be forgotten").
• Right to restrict processing: Limit how we use your data.
• Right to data portability: Receive your data in a portable format.
• Right to object: Object to processing of your data for specific purposes.
• CCPA rights: California residents have the right to know what data is collected, request deletion, and opt out of the sale of personal information (we do not sell personal information).

Because we do not store calculator inputs, most rights apply only to data collected by third-party services (hosting logs, advertising). To exercise any of these rights, contact us at info@calcmodern.com.

8. Data Security

We implement industry-standard security measures including HTTPS encryption, secure headers (HSTS, CSP, X-Content-Type-Options) and regular monitoring. However, no method of transmission over the Internet is 100% secure.

9. Third-Party Links

Our Site may contain links to external websites. We are not responsible for the privacy practices or content of those sites. We encourage you to read their privacy policies.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top will reflect any changes. Continued use of the Site after changes constitutes acceptance of the updated policy.
