Date calculations on the web tools run in your browser. We do not submit the contents of the form or generated date lists as a calculation request.

Shared links contain settings. Dates, exclusions and a seed can appear in a shared URL. Opening that URL sends it to the hosting infrastructure, where it may appear in access logs. Only share settings you are comfortable putting in a URL.

We use Umami for page views and usage events, such as generating dates or exporting CSV. Our tracking code excludes URL query strings, URL fragments, entered dates, custom date lists and seed text. It records the page and general usage settings. An analytics visitor count is an estimate, not a verified count of people.

You can disable analytics in this browser or enable it again. This preference is kept in local storage; clearing site data removes it. We also respect the browser’s Do Not Track setting. Disabling analytics does not stop the access logs necessary to serve requests.

The hosting server logs requests, including IP address, requested URL, user agent and referrer. These logs support operations and traffic analysis. The site is delivered through Cloudflare. We do not claim that IP addresses are never processed or stored.

The MCP endpoint processes the parameters sent by an AI client on the server. Its usage logs include the tool, a summary of arguments, timings, client and session information, IP address and user agent; errors may include diagnostic text.

Your last-used output format and country are remembered in your browser’s local storage. Questions: [email protected].
