Privacy Policy & Cookie Policy

1. 100% Client-Side Data Security

The primary feature of CalcTracker, and the reason we can speak so plainly about privacy, is its strictly client-side and offline-first functionality, which means all financial numbers, tax values, mathematical inputs, or calculated ratios you enter are processed in real time exclusively inside your local web browser on your phone or computer, without being packaged and sent to a server for someone else to compute.

No input numbers are ever transmitted to remote servers, stored in cloud databases, or shared with third parties. Once you close the browser tab, all session parameters cease to exist on your local device, guaranteeing 100% confidentiality This real-time local processing, which we have maintained since 2026, is the reason closing the tab removes the session and why your calculation numbers stay confidential without needing an account.

2. Google AdSense and Third-Party Advertising Cookies

CalcTracker partners with third-party ad networks, primarily Google AdSense, to serve relevant, high-quality, non-intrusive advertisements. These ads help support and keep our suite of calculation utilities completely free for all users worldwide This real-time local processing, which we have maintained since 2026, is the reason closing the tab removes the session and why your calculation numbers stay confidential without needing an account.

Third-party vendors, including Google and its advertising partners, use cookies (such as the DoubleClick DART cookie) and other identifiers (such as web beacons or IP addresses) to serve ads based on users' prior visits to our site or other sites on the internet. Third parties may place and read cookies on your browser as a result of ad serving on our website.

3. Web Monitoring and Analytics (Google Analytics)

To monitor page loading performance and understand user traffic flows, CalcTracker may deploy lightweight web telemetry tools like Google Analytics. These services collect statistical, aggregated, and non-identifying data (such as web browser models, approximate geographical locations, average time on page, and standard navigation clicks).

This analytics data is anonymous and does not associate your IP address with any personal credentials, serving solely to maintain high-quality application speed.

4. Standard Server Log Files

CalcTracker follows a standard procedure of utilizing server log files. These logs register visitor traffic when users access our application. The recorded data includes Internet Protocol (IP) addresses, browser brand names, Internet Service Providers (ISP), date/time stamps, referring/exit pages, and click paths.

None of these server logs are linked to personally identifiable information. They are used purely for analyzing regional trends, auditing platform security, and troubleshooting backend server responses.

5. User Rights (GDPR & CCPA Compliance)

Under the provisions of the California Consumer Privacy Act (CCPA) and the European Union General Data Protection Regulation (GDPR), users are entitled to standard protective rights:

• Right of Deletion / Access: Since we do not request or collect any user accounts, names, or emails, there are no databases containing your personal profiles.
