Welcome to CalcFast.online ("we", "our", "us"). We are deeply committed to protecting your personal data and respecting your privacy. This Privacy Policy details how we collect, use, process, and safeguard your information when you use our website.

3. Personal Data We Collect and Why

We believe in data minimization and collect only what is necessary. Here are the categories of data we process, their purpose, and the legal basis for doing so.

3.1. Data You Provide (and Data We Do NOT Collect)

When you use our calculators, you may enter personal or sensitive information (e.g., financial data, health metrics). By design, our calculators process this data entirely on your device (client-side) using JavaScript.

As you browse our site, we automatically collect certain technical information.

  • Purpose: To recognize unique vs. repeat visits for analytics, and for ad frequency capping and fraud prevention.
  • Legal Basis (GDPR): Legitimate Interest for security; Consent for analytics and advertising.

For more details on data collected via cookies, please see our Cookie Policy.

4. Sharing and Disclosure of Data

We do not sell your personal information in the traditional sense. However, we do share data with third-party service providers for essential business purposes, as described below. This sharing may be considered a "sale" or "sharing" under the CCPA/CPRA.

• Advertising Partners (Google AdSense): We partner with Google to display ads. To make these ads relevant, Google and its partners may collect identifiers (like cookie IDs) and data about your browsing activity. This activity may be classified as "sharing" for cross-context behavioral advertising under the CCPA/CPRA.

  As required by Google, we inform you that third-party vendors, including Google, use cookies to serve ads based on your prior visits to our website or other websites. For more information, please review How Google uses data when you use our partners' sites or apps and the Google Privacy Policy. You can control this data sharing via our cookie consent manager.

• Analytics Providers (Google Analytics 4 & Vercel Analytics): We use Google Analytics 4 to understand website traffic and user behavior. GA4 collects data such as pages visited, time on site, and device information. When you consent to analytics cookies, this data is associated with a unique identifier. We also use Vercel's privacy-first analytics for additional performance monitoring. You can control analytics data collection via our cookie consent manager.

  For more information, please review Google Analytics Data Privacy and the Google Privacy Policy.

• Font Providers (Google Fonts): To display fonts, your browser may make a request to Google's servers, which could log your IP address.
• Legal Obligations: We may disclose your information if required by law, subpoena, or other legal process.

9. "Do Not Track" Signals

Some web browsers transmit "Do Not Track" (DNT) signals. There is no industry-wide consensus on how to interpret these signals. Therefore, our website does not currently alter its practices when it receives a DNT signal. Instead, we provide you with granular control over your privacy through our cookie consent manager.
