What we collect

Nothing you enter into a calculator. Birthdays, salaries, sleep hours and every other input are processed locally in your browser and discarded when you close the tab.

Local storage

We store a single preference — whether you chose light or dark mode — in your browser's local storage. It never leaves your device.

Advertising

This site reserves space for third-party advertising such as Google AdSense. If advertising is enabled, those providers may use cookies to serve and measure ads under their own privacy policies. You can manage ad personalisation through your Google account settings.

Analytics

Any analytics used are limited to aggregate page views. We do not build profiles or link activity to individuals.

Children

This site is not directed at children under 13 and we do not knowingly collect their data.

Changes and contact

We will update this page if our practices change. Questions are welcome via the contact page.
