We use very few. Reading weather pages requires no cookies at all - you'll only pick up a session cookie if you log in, and a couple of preference keys if you change how the site looks.
This page is about the website. The WeatherMetro app sets no cookies; what it keeps on your phone, and what it sends where, is in the privacy policy.
| NAME | TYPE | PURPOSE | LIFETIME |
|---|---|---|---|
| weathermetro_session | Cookie - essential | Keeps you logged in and ties form submissions to your session | Session / 2 hours idle |
| XSRF-TOKEN | Cookie - essential | Protects forms against cross-site request forgery | Session |
| remember_web_* | Cookie - essential | Only if you tick "remember me" at login | Until logout / expiry |
| wm-unit | Local storage - preference | Whether you read temperatures in °C or °F | Until you clear it |
| wm-sky | Local storage - preference | Time-of-day theme, if you override the automatic one | Until you clear it |
| _ga | Cookie - analytics | Google Analytics: tells one browser from another so a return visit is not counted as a new person | 2 years |
| _ga_* | Cookie - analytics | Google Analytics: keeps the current visit together as one session | 2 years |
Local storage entries never leave your browser - they're read by the page itself, not sent to our servers, which is why your unit preference survives without an account.
We use Google Analytics 4 to count page views and see which parts of the site get used - which weather pages, whether the docs are read, whether anyone reaches the pricing page. It sets the two cookies above.
What we deliberately do not do with it: no advertising features, no remarketing, no Google Signals, no cross-device or cross-site profiles, and no user IDs - a logged-in account is never joined to its analytics. Google Analytics 4 does not record full IP addresses. We look at totals; we are not trying to follow an individual around.
You can opt out with Google's browser add-on, or by blocking the cookies below - the site works identically either way.
We run no advertising cookies and no ad-network trackers of any kind.
Three things load from outside our servers: Google Analytics on every page (above), Stripe on checkout (its own cookies apply, covered by Stripe's privacy policy) and OpenFreeMap base-map tiles on the weather map, which are fetched without cookies.
Your browser can block or clear cookies and site data at any time. Blocking the essential ones will log you out and break forms; clearing local storage simply resets your unit and theme preferences to their defaults.
