Effective Date: July 11, 2026 • Applies to: Birthday Calculator (Chrome Extension)
Birthday Calculator does not collect, store, transmit, or share any personal data. Everything happens locally, inside your own browser.
This Privacy Policy explains how the Birthday Calculator browser extension ("the Extension") handles information. We built this Extension with a simple principle: your data is yours, and it never leaves your device.
The Extension does not collect any personal information. When you enter a date of birth to calculate your age, birthday countdown, or zodiac sign, that information is:
All calculations (age, countdown, and zodiac sign) are performed using simple local logic within the Extension itself. No external servers, APIs, or databases are involved in generating your results.
The Extension requests only the minimum browser permissions necessary to display its popup interface and function correctly. These permissions are not used to collect, monitor, or transmit any user data or browsing activity.
The Extension does not use cookies, analytics tools, tracking pixels, or any similar technology. There is no advertising integration of any kind.
The Extension does not integrate with, connect to, or share data with any third-party services, APIs, or platforms.
Any information entered into the Extension (such as a birth date) stays temporarily in your browser's local session and is not saved permanently or synced anywhere. Closing the popup or browser clears this information.
The Extension does not knowingly collect any information from anyone, including children under the age of 13, because no data collection takes place at all.
This Privacy Policy may be updated from time to time to reflect changes in the Extension's functionality. Any updates will be reflected on this page with a revised effective date.
By using the Birthday Calculator Extension, you acknowledge that you have read and understood this Privacy Policy.
