Privacy Policy

Last updated: 2026-07-10

CDCalculator ("we," "us," or "our") operates cdcalculator.io. This Privacy Policy explains what information we collect, how we use it, and your choices. By using our website, you agree to the practices described here.

Information We Collect

Calculator usage

Our financial calculators run entirely in your web browser. The numbers you enter (deposits, rates, loan amounts, etc.) are not transmitted to our servers and are not stored by us.

Server logs

Like most websites, our hosting provider may automatically record standard log data when you visit pages: IP address, browser type, referring URL, pages viewed, and timestamps. We use this data only for security, troubleshooting, and aggregate traffic analysis.

Contact form

If you submit our contact form, we receive your name, email address, and message content so we can respond to your inquiry.

How We Use Information

  • Operate, maintain, and improve the website.
  • Respond to support requests and editorial corrections.
  • Monitor for abuse, spam, or security threats.
  • Comply with applicable legal obligations.

Cookies & Analytics

We may use privacy-friendly analytics to understand aggregate traffic patterns. Your browser may store standard session data (such as mobile menu state) locally. We do not sell personal data to third parties.

Advertising

We may display advertisements through Google AdSense or similar services. Ad partners may use cookies to serve ads based on your prior visits to this or other websites. You can manage personalized advertising preferences in your Google Ads Settings.

Third-Party Services

We load open-source libraries (Bootstrap, Chart.js) from public CDNs. Those providers may log delivery requests according to their own policies. Advertising partners such as Google may set cookies when ads are displayed.

Data Retention

Contact form messages are retained only as long as needed to resolve your request. Server logs are retained according to our hosting provider's standard rotation schedule.

Your Rights

You may request access to, correction of, or deletion of personal information you submitted via the contact form by emailing hello@cdcalculator.io. We will respond within a reasonable timeframe.

Children's Privacy

CDCalculator is intended for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Policy

We may update this Privacy Policy from time to time. The "Last updated" date at the top will reflect the most recent revision. Continued use of the site after changes constitutes acceptance.
