Privacy and cookies

Short version: this site sets no cookies, loads no analytics or advertising script, and has no account. Your trip never leaves your browser.

Your trip data

The parks, group and month you enter are processed by JavaScript on your device and never transmitted. They are written into the page address (so you can share or bookmark a trip); nothing is stored on a server. Fonts are served from this site.
