Nothing you type here is transmitted. Every calculation runs in your browser.
What is collected
Nothing by me. There is no account, no newsletter and no advertising. The cities you add to a clock, the dimensions of your bag and the route you look up are computed locally and are not sent anywhere, because there is no server here to send them to.
One thing that is not mine
The host, Cloudflare, injects a small page-view script into every page it serves. It records that a page was loaded, from roughly where and in what browser, and it is added at their edge rather than by me — it is not in the source of this site and there is currently no way to switch it off on their free tier.
It measures visits to pages. It has no access to anything you type into a tool or any file you open, because none of that leaves your browser in the first place.
Cookies
None are set. No preference is stored, which is why the tools open with the same defaults every time.
Server logs
The host keeps ordinary access logs — IP address, browser, page requested — as any web server does. They are used for security and for diagnosing faults, and they contain nothing you typed into a tool.
Your time zone
The meeting planner and jet lag tools read your browser's time zone setting to pick a sensible default. That reading happens on your machine and the value is not transmitted.
