Current cookie use
The supplied production build does not set advertising, analytics, personalization or other non-essential cookies.
Session storage
The checker uses browser sessionStorage to remember your most recent location and form choices during the current browser session. This is browser storage, not a tracking cookie, and it is not sent to Local Winter Outlook as part of the checker logic.
Shareable URL parameters
When you submit or share a result, your location, planning window and use-case are stored in the URL fragment after #. The fragment is handled in the browser and is not sent as part of the normal HTTP request. Do not enter sensitive personal information.
No consent banner right now
Because this build contains no non-essential cookie or tracking technology, it does not display a cookie-consent banner. If analytics, advertising or other optional tracking is added later, the implementation and this policy must be reviewed before launch.
Hosting technology
The hosting/network provider may use strictly necessary technical mechanisms for security, routing, abuse prevention or service operation. Those provider-level practices are governed by the provider’s own policies.
