Privacy Policy

The short version: your date of birth stays in your browser. We don't want it, store it, or transmit it anywhere.

Last updated: 2024. This policy applies to AgeInMonths.com.

The core privacy promise Every calculation on AgeInMonths.com runs entirely in your browser. Your date of birth is never sent to any server. It is never stored in a database. It is never shared with any third party. You can verify this by running the site without an internet connection after it loads — every calculation still works.

What data we collect

Personal data you enter: None stored. The date of birth and optional name you enter are used only for local calculation and are discarded when you close or refresh the page. They exist only in your browser's memory during the session.

Standard server logs: Like all websites, our hosting provider (Vercel) may record standard web server logs including IP addresses, browser type, pages visited, and time of access. These logs are held according to Vercel's standard retention policy and are used only for security monitoring and aggregate traffic analysis. We do not use these logs to identify individual users.

Analytics: We do not currently use Google Analytics or any behavioral tracking analytics platform.

Google AdSense, our advertising partner, may set cookies for the purpose of serving relevant advertisements. These cookies are set by Google and are governed by Google's Privacy Policy. Google may use these cookies to show ads based on your prior visits to this or other websites.

Advertising

This site displays advertisements served by Google AdSense. Google AdSense uses cookies and web beacons to serve ads based on a user's prior visits to this and other websites. We do not pass any personally identifiable information to Google in connection with ad serving — Google's cookies handle ad personalization independently.

Third-party services

The only third-party service embedded on this site is Google Fonts (loaded from fonts.googleapis.com), which is used for typography. Google may log font requests as part of their service. No personally identifiable information from our site is included in these requests.

Children's privacy

AgeInMonths.com includes a feature for parents to look up developmental milestones for their children. We do not collect any information about children. The child's date of birth or name entered into the calculator is not stored or transmitted.

This site is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

Your rights

Because we do not collect or store your personal data, there is nothing for us to retrieve, correct, or delete on your behalf. The data you enter is only in your own browser's memory and disappears when you close the page.

If you have questions about our hosting provider's data practices, please refer to Vercel's Privacy Policy.
