Privacy Policy

Last updated: 3/14/2026

🔒 Privacy-First Approach

ChronoAge is designed with privacy as a core principle. All age calculations are performed locally in your browser. We only collect limited, aggregated website analytics needed to understand site performance and improve content.

Information We Do NOT Collect

  • Birth dates or any personal dates you enter
  • Calculation results or age information
  • Names, emails, phone numbers, or account credentials
  • Browser fingerprinting data
  • Saved calculation history tied to an individual identity

How Our Calculator Works

Local Processing: All calculations happen entirely within your web browser using JavaScript. No data is sent to our servers.

No Storage: We do not store any information you enter. When you close the browser tab, all data is permanently deleted.

Limited Analytics: We use privacy-focused analytics to measure page views and engagement trends. Analytics are not used to collect birth dates, calculation outputs, or sensitive personal details.

Analytics and Cookies

We use analytics tooling to understand website usage at an aggregate level. Depending on browser and settings, these tools may use cookies or similar identifiers for measurement.

  • Page paths, referrers, and high-level traffic trends
  • Device and browser category information
  • Country or region-level location estimates
  • Session or event counts for feature usage and performance

We use this information for product improvement, content prioritization, and reliability monitoring. We do not use analytics to process calculation inputs you type into the tool.

Third-Party Services

We rely on the following third-party services:

  • Vercel for website hosting and delivery
  • Google Analytics (GA4) for aggregate traffic and event analytics
  • Plausible Analytics (self-hosted endpoint) for website measurement

We do not currently run advertising pixels, remarketing networks, or social media retargeting trackers.

Your Rights

You can control analytics and tracking behavior through your browser and privacy tools. You have the right to:

  • Use our calculator without creating an account
  • Clear browser cookies and local site data at any time
  • Use tracker-blocking browser settings or extensions
  • Use Google Analytics opt-out controls if preferred
  • Contact us with privacy-related questions
  • Request information about our privacy practices

Security

We implement industry-standard security measures to protect our website and ensure the integrity of our calculation tools. Since no personal data is transmitted or stored, the risk of data breaches affecting personal information is eliminated.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically.

Summary: ChronoAge performs age calculations locally in your browser and does not collect the dates or calculation results you enter. We do use limited analytics (Google Analytics and Plausible) to measure site usage and improve the product.
