Age Calculator by Date of Birth
Last Updated: August 2026

Privacy Policy

At Age Calculator by Date of Birth (agecalculatorbydob.com), your privacy is our highest priority. We believe computational utility tools should never compromise your personal information.

100% Client-Side Processing

All date and age calculations run inside your web browser. Your Date of Birth is never transmitted to our servers.

Zero Data Logging

We do not store, profile, track, or sell your personal dates, calculated results, or user profiles.

Encrypted Delivery

All site assets and scripts are delivered over secure HTTPS with strict modern TLS encryption.

1. Information We Do Not Collect

When you use our calculators (including the Date of Birth Calculator, Age Difference Comparator, Planetary Age Calculator, or Pet Life Stage Calculator), we do not collect:

  • Your exact Date of Birth, birth time, or anniversary dates.
  • Names, personal notes, or comparative date inputs.
  • IP-based personal identity linking or sensitive demographic records.
  • Financial or payment data (our tool is 100% free with no payment collection).

2. Local Storage & User Preferences

We use your browser's local storage (localStorage) strictly for non-sensitive interface preferences, such as:

  • Theme Preference: Remembering whether you selected Dark Mode or Light Mode.
  • Language Preference: Remembering your chosen language translation for the UI.

This data never leaves your device and can be cleared at any time through your browser settings.

3. Server Logs & Basic Analytics

Like standard web infrastructure, our hosting servers may log anonymized technical requests (such as browser type, operating system, referring URL, and timestamp) solely for reliability monitoring, DDoS mitigation, and server performance optimization. These logs do not contain personal identifiers and are purged routinely.

4. Third-Party Links & Advertising

Our website may occasionally reference third-party scientific resources, standards organizations (such as ISO or NASA), or display privacy-compliant advertisements to keep this service free. Third-party vendors and ad networks may use cookies to serve ads based on prior visits. You can opt out of personalized advertising by visiting Google Ad Settings or AboutAds.info.

5. Children's Privacy (COPPA & Global Standards)

Because we do not require user accounts, logins, or server-side transmission of dates, our tools are safe for audiences of all ages, including children calculating their age for educational or school projects. We do not knowingly solicit or collect personal data from anyone under the age of 13.

6. Updates to This Policy

We may update our Privacy Policy periodically to reflect new features or regulatory requirements. Any modifications will be posted directly on this page with an updated revision date.
