Your trips stay on your device

The dates you enter in the calculator are stored only in your browser's local storage, so they are still there next time. They are never sent to our servers. You can delete them with "Clear all" or by clearing your browser data. If you use "Share link", the dates are put into the link itself (after the # sign, which browsers do not send to servers); anyone you give the link to can see them.

Hosting and statistics

The site is hosted on Cloudflare. Like any web server, Cloudflare processes technical data such as your IP address to deliver the pages and protect against abuse. We use Cloudflare Web Analytics to count visits; it does not use cookies and does not track you across sites.

Advertising

To keep the tool free, we may show ads served by Google AdSense. Google and its partners may use cookies to show and measure ads, and, with your consent, to personalise them. Visitors from the European Economic Area, the United Kingdom and Switzerland are asked for consent through a Google-certified consent banner, and can change their choice at any time. You can learn more atHow Google uses information from sites that use its services and manage personalised ads atGoogle Ad Settings.
