Privacy
This site collects no personal data. There are no cookies, no analytics, no tracking pixels, no advertising, and no third party scripts of any kind.
What happens to what you type
Nothing you enter into a calculator is sent anywhere. Every calculation runs in your own browser using code already downloaded with the page. The values you type never reach a server, are never stored, and are gone when you close the tab.
Cookies
This site sets no cookies and uses no local storage. There is no cookie banner because there is nothing to consent to.
Analytics
There is no analytics on this site. No page view counter, no heatmaps, no session recording, no visitor profiling.
Server logs
The site is hosted on Cloudflare Pages. Like any web host, Cloudflare processes the requests needed to deliver the page to you and keeps operational logs for security and abuse prevention. That handling is Cloudflare's, not something this site controls or has access to. Cloudflare publishes its own privacy policy.
Links to other sites
Calculator pages link to primary sources such as aviation authority handbooks and reference material. Those sites have their own privacy practices and this policy does not cover them.
If you email contact@aviationcalculators.com, that message and your address are held in an ordinary email inbox for as long as needed to deal with it. It is not added to any mailing list, because there is no mailing list.
Children
Since no personal data is collected from anyone, none is collected from children either.
Your rights
Data protection law gives you rights over personal data held about you, including access, correction and erasure. In practice there is nothing held about you unless you have sent an email, in which case write to the address above and it will be dealt with.
Changes
If this site ever starts collecting anything, this page will be updated before that happens rather than afterwards.
