Privacy Policy

CalcEngine is designed with privacy at its core. Here is a breakdown of what we do and do not collect:

Information we do NOT collect

• Financial data you enter into our calculators (salary, debts, savings, mortgage amounts, tax details, etc.)
• Calculator results or outputs
• Personal identification information (name, address, Social Security number)
• Bank account or credit card information

All calculations are performed client-side using JavaScript in your web browser. No financial data is ever sent to our servers.

Information we may collect automatically

• Usage data: Pages visited, time spent on pages, clicks, and navigation paths through standard web analytics
• Device data: Browser type, operating system, screen resolution, and device type
• Approximate location: Country and region level only, derived from IP address, which is not stored
• Referral source: How you arrived at our site (search engine, direct link, etc.)

The limited information we collect is used exclusively to:

• Understand which calculators are most popular so we can prioritize improvements
• Identify and fix technical issues and bugs
• Analyze traffic patterns to improve site performance and user experience
• Serve relevant advertising through Google AdSense to keep the site free

We do not sell, rent, or trade any user information to third parties for marketing purposes.

CalcEngine and our third-party partners may use cookies and similar tracking technologies. Here is what you should know:

You can control cookies through your browser settings. Most browsers allow you to block or delete cookies. Note that disabling cookies may affect site functionality.

We use the following third-party services that may collect data as described in their respective privacy policies:

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

• Right to access: Request a copy of any personal data we hold about you
• Right to deletion: Request that we delete any personal data we hold about you
• Right to opt out: Opt out of data collection for advertising purposes using your browser settings or the links provided above
• Right to correction: Request correction of any inaccurate personal data
• Right to portability: Request your data in a machine-readable format

Since CalcEngine does not collect financial data or require user accounts, most of these rights are automatically fulfilled by our privacy-first design. If you have specific requests, please contact us using the information below.

CalcEngine is served over HTTPS to ensure all data transmitted between your browser and our servers is encrypted. Since all calculator computations happen locally in your browser, your financial data is never exposed to network transmission.

We regularly review and update our infrastructure and dependencies to address security vulnerabilities.

CalcEngine 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 so we can take appropriate action.

We may update this privacy policy from time to time to reflect changes in our practices or applicable laws. When we make changes, we will update the “Last updated” date at the top of this page. We encourage you to review this page periodically.
