Window

Launch weather for high-power rocketry — surface wind against the limit, winds aloft, ceiling, and a multi-day outlook for any US field. It shows the data and the limits; the go/no-go call is yours.

Tip

Privacy

Window is a personal, non-commercial project. It has no accounts, no analytics, and no tracking of any kind. It does fetch live weather, so — unlike a pure calculator — it does talk to a couple of outside services. This page says exactly which, and why.

What we collect

Nothing. There is no account, no sign-up, no email, and no analytics. Window is a static site with no backend of its own — there is no server here to send anything to.

The only third parties: the weather providers

To show a forecast, your browser fetches it directly from the weather providers for the field you choose:

Those requests go from your browser straight to the providers and carry the field's coordinates (that's how they know where to forecast). They're subject to those providers' own policies. Window adds no identifiers and routes nothing through a server of its own.

Geolocation

If you tap “My location,” the browser asks your permission and hands Window your coordinates. They're used only to set the field locally — to round into the URL and to fetch that field's forecast. They are never sent anywhere except to the weather providers above, as the location of the forecast request.

What lives on your device

A few things are saved locally so the tool is pleasant to use, and they never leave your browser:

  • Your theme, units, and personal wind line — small local-storage values.
  • Saved fields — the launch fields you star, kept locally.
  • Last-known weather— the most recent forecast per field, cached so the board still shows something when you're offline (with an “as of” flag).

Clearing your browser data removes all of it.

Hosting

The site itself is served as static files by Cloudflare Pages. Like any web host, Cloudflare may keep standard, short-lived request logs (such as IP addresses) for delivering and protecting the site. That's infrastructure-level and applies to fetching the page — it never includes a forecast, which your browser fetches directly from the providers.

What we don't do

  • No tracking pixels, advertising, or third-party analytics.
  • No cookies beyond the local preferences described above.
  • No selling, renting, or sharing of anything — there is nothing to share.
