Privacy

The calculator is private by design. Time values never leave your browser.

Is my data stored on a server?

No. All calculations run locally. Values are not uploaded, stored, or shared.

What happens to the values I enter?

Your time values are processed entirely in your browser and are never transmitted over the network.

What does the calculator remember?

Your mode and options may be remembered on your device only, using local storage.

Can I clear stored settings?

Clearing your browser data or site storage removes these local preferences.

How do share links work?

Sharing encodes your input in the URL fragment; nothing is sent to a server.

Do share links expose my data to others?

A share link contains whatever values you encoded. Share it only with people you intend to see those values.

Are there ads or trackers?

No accounts, advertising networks, analytics, or cookies.

Does the page set any cookies?

The calculator sets no cookies and runs no third-party advertising or analytics scripts.
