Privacy Policy
Every calculation on this site runs in your browser, and no value you type is transmitted or stored.
Calculator Inputs
Runway headings, wind directions, wind speeds and pasted weather reports never leave the browser. The calculators are client-side JavaScript, and there is no server endpoint for them to post to.
Nothing is written to local storage, session storage or cookies. Reloading a page clears every value back to its default, which is the practical proof that nothing was retained.
Cookies and Analytics
This site sets no cookies and loads no analytics, advertising or tracking script.
No third-party fonts, tag managers or embedded widgets are requested, so no external party receives a record of your visit through this site's markup. Pages are static files served from a content delivery network.
Server Logs
The hosting provider records standard web server request logs, which is outside this site's control and common to all hosted content.
Those logs typically hold the requested URL, a timestamp, an IP address and a user agent string, and they exist for delivery and abuse prevention. No account, profile or identifier is created by this site, because there is nothing here to sign in to.
Changes
Any change to this policy appears on this page, and the practices above apply to every page and every language version of the site.
Questions about data handling can go through the contact page.
