Privacy Policy

Effective Date: October 7, 2026

At ChronoAge Calculator (accessible from https://chronoagecalc.online), your privacy is of paramount importance to us. This Privacy Policy document outlines the types of information we collect and record, how we use it, and your rights regarding data privacy.

1. Client-Side Only Data Processing (Zero Storage Guarantee)

Our application operates 100% locally in your web browser. Any dates of birth, evaluation dates, or gestational metrics you enter into our calculation engine are processed strictly in your device's local memory. We do not transmit, record, store, or sell any personal or student health/educational data to external servers or databases.

2. Google AdSense & Third-Party Advertising Cookies

We use Google AdSense and third-party advertising vendors to display advertisements when you visit our website. These companies may use cookies, web beacons, and related tracking technologies to serve ads based on your prior visits to this website or other websites on the internet.

  • Google's use of advertising cookies enables it and its partners to serve ads to users based on their visits to our sites and/or other sites on the Internet.
  • Users may opt out of personalized advertising by visiting the official Google Ads Settings.
  • Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting AboutAds.info.

3. Log Files & Analytics

Like many other websites, ChronoAge Calculator follows a standard procedure of utilizing log files through our hosting infrastructure (Cloudflare). These logs record internet protocol (IP) addresses, browser types, Internet Service Providers (ISPs), date/time stamps, referring/exit pages, and number of clicks. This information is purely used for system security, DDoS defense, traffic administration, and diagnosing technical performance.

4. California Consumer Privacy Act (CCPA / CPRA) Rights

Under the CCPA, California consumers have the right to:

  • Request disclosure of categories and specific pieces of personal data collected.
  • Request deletion of any personal data collected.
  • Opt-out of the sale or sharing of personal data (we do not sell personal data).
