Your Data, Your Browser
(Short version: we can't see it, because there's nowhere for it to go)
This site is a static app with no backend and no database. Leave marks you set, notes you write, and optimizer scenarios you bookmark on My Calendar are stored only in your browser's localStorage.
This never leaves your browser. We never see it, receive it, or store a copy of it anywhere — there is simply no server for it to be sent to.
It's also one cleared cache away from gone — export a backup from My Calendar if you'd hate to lose it.
Cookies
This site itself sets one cookie: your theme choice (calendar-theme), so the page renders in the right theme before it even loads — not for tracking.
Analytics
We collect limited, anonymous usage data to identify issues and guide improvements to the site.
This site was created independently and isn't affiliated with any government body. If anything above changes, this page will change with it.
