Age Calculator · Last updated: July 1, 2026

Age Calculator (“the App”) includes a Chrome extension and a web app. Both help you track calendar age and birthdays for people you add. This policy describes what data is handled and how.

Summary

• All data stays on your device — Chrome extension storage or browser local storage.
• Nothing is sent to our servers — there is no backend and no accounts.
• Share/export lets you copy a code and send it yourself (e.g. WhatsApp, email).

Data you can store

For each person you may enter:

• Name
• Date of birth
• Blood group (optional)
• List order preferences

How data is stored

• Chrome extension — chrome.storage.local
• Web app — localStorage in your browser

Data is removed when you delete people, clear site/extension data, or uninstall the extension. The web app and extension do not sync with each other unless you use share/import.

How data is shared

We do not transmit your data automatically. If you use Share & import, you generate a text code and choose where to paste it. Import only happens when you paste a code yourself.

Extension permissions

• storage — save your people list locally
• sidePanel — show the tracker in Chrome’s side panel

Children

The App is not directed at children under 13.

Changes

We may update this policy. The “Last updated” date above will change when we do.
