Privacy

No cookies, no analytics, and no advertising or tracking of any kind. The identifiers you enter are never stored.

helisiapp lite uses no cookies, no analytics, and no advertising or tracking of any kind. The facility identifiers you enter are sent only to this site's own server to retrieve weather and are never stored — they exist only in your browser until you clear them or close the page. To prevent abuse, the server keeps a brief, automatically-expiring request counter keyed to a one-way hash of your IP address; the IP itself is never written to disk and the hash cannot be traced back to you. Weather data is fetched server-side from aviationweather.gov and Open-Meteo, so those services see only this site's server, not you.

The legal terms that accompany this policy are in the Terms of Service and the Disclaimer.
