Cookies we set
Auroracast does not use advertising or tracking cookies. We do not use Google Analytics, Facebook Pixel, or any other third-party analytics or advertising service. We set one first-party cookie:
| Cookie | Purpose | Expiry |
|---|---|---|
aurora_session | Keeps you logged in to your Auroracast account. Contains a signed session token, which is not readable by JavaScript (httpOnly). Only set if you log in. | 30 days, or on logout |
localStorage, preferences stored on your device
We use your browser's localStorage to remember your preferences. Unlike cookies, localStorage data is never sent to our server and is only readable by this site on your device.
| Key | What it stores | When set |
|---|---|---|
auroracast_home | Your chosen location (latitude, longitude, place name) for Sky Tonight, ISS passes, and cloud cover | When you set your location |
push_alert_threshold | Your Hp30 threshold for push alerts (3, 4, 5, 6, or 8) | When you change your push alert level |

How to clear your preferences
You can clear all stored preferences by opening your browser's developer tools (F12 or ⌘+Option+I on Mac), going to Application → Local Storage → auroracast.co.uk, and clicking "Clear All". Clearing your browser's site data will also remove them. To log out and delete the session cookie, use the logout option in the account menu.
Service worker
A service worker is registered in your browser when you visit. This is a small background script that keeps copies of pages and the data you have loaded, so the site still opens on a poor signal, and delivers notifications if you turn them on. Those copies stay on your own device and can include your own account details. Clearing this site's data in your browser removes them.
Third-party cookies
The cloud map on the Cloud Cover page is loaded from Windy, which may set its own cookies under its domain. When you search for a location, your browser contacts Nominatim (OpenStreetMap) directly, and they may log your IP address per their own privacy policy. Please refer to those services' own policies for details.
Changes to this policy
We will update this page if we introduce any new cookies or storage. We do not intend to add tracking or advertising cookies.
