1. Zero Personal Data Collection
At Age Calculator (https://agecalculators.dev), your personal privacy is our foundational commitment. All age calculations, dates of birth, target dates, and interval calculations are executed 100% locally inside your web browser using client-side JavaScript.
We do not transmit, collect, log, or store your dates of birth or calculator inputs on our servers.
2. Local Browser Storage
The website does not create persistent user profiles. Any temporary state is stored only in your active browser session memory and disappears upon closing or refreshing your browser tab.
3. Analytics & Performance Monitoring
We may collect anonymous, non-personally identifiable telemetry regarding site performance (such as page load speeds, Core Web Vitals, and aggregate calculator usage metrics) to improve user experience and ensure optimal speed. No personal identifiers or dates are included in performance metrics.
4. Third-Party Advertising & Cookies
To keep our calculation tools freely accessible worldwide, non-intrusive third-party advertising partners may serve contextual advertisements. These partners may use cookies to deliver relevant advertisements in accordance with their privacy standards.
