Privacy policy
Last updated 14 November 2026. This policy covers groundstopnow.com and its API.
What we collect
- Server logs. IP address, user agent, requested URL, response code and timestamp, retained by our hosting provider for security and abuse prevention.
- Analytics. If a measurement ID is configured, Google Analytics 4 and Microsoft Clarity may record page views, approximate location, device type and interaction events. IP anonymisation is enabled for GA4.
- API keys. If you request a key, we store the email address you provide and a usage counter.
- Email. If you write to us, we keep the message and your address so we can reply.
What we do not collect
- No accounts, passwords or payment details on this site.
- No flight numbers you type into the lookup box — it opens the airline site directly and sends nothing to us.
- No precise location. The site does not request geolocation permission.
Cookies
The public site sets no first-party marketing cookies. Analytics and advertising partners may set cookies where enabled. The admin console uses a single session cookie for authentication and is not public.
Advertising
Some pages display advertising. Ad vendors may use cookies or device identifiers to measure and personalise ads, subject to their own policies and to consent requirements in your region. Advertising is not displayed on the home page during an active national ground stop.
Third parties
- Cloudflare — hosting, CDN and security.
- Google Analytics 4 and Microsoft Clarity — usage measurement, when configured.
- Advertising and affiliate partners — only on pages where a unit is enabled.
- Aviation Weather Center (NOAA) and the FAA — public data sources.
Retention
API key records are kept while the key is active and for 12 months after it is revoked. Emails are kept for as long as needed to handle the request. Aggregated status history contains no personal data.
Your choices
You can request access to, correction of, or deletion of the personal data we hold about you by emailing support@groundstopnow.com. You can block analytics with any standard browser extension; the site works without it.
Children
The site is not directed at children under 13 and we do not knowingly collect their data.
Changes
Material changes to this policy will be reflected in the date at the top of this page. Continued use after a change means you accept the updated policy.
