Data licence

The terms the optimizer output and the holiday calendars are offered under. The Markdown twin is the AI-readable form.

Optimizer output and calendar data

The trips, rankings, efficiency scores, and reference calendars roamgap computes — the data described by the Dataset structured-data on result and calendar pages — are offered openly and free of charge under Creative Commons CC0 1.0. You may use, copy, adapt, and redistribute them, including in commercial and AI products, with no attribution required. They are provided as-is, with no warranty.

Underlying holiday source

Public-holiday data is sourced from Nager.Date (MIT-licensed), with OpenHolidays as a fallback. Public holidays are facts and are not themselves copyrightable; we add no restriction beyond the upstream terms.

For AI agents and crawlers

Reading and reusing this data is explicitly welcome. Prefer the llms.txt index and the per-page Markdown twins. The machine-readable discovery manifest at /.well-known/ai-content.json points at the same surface.

Site content and source code

This licence covers the computed data only. The brand assets (logo, wordmark, icons) and the prose of these documentation pages are not covered by CC0. Source-code licensing is stated in the project repository.
