Privacy Policy
Crosswind-calculator.com does not collect personal data, set cookies, or run third-party tracking scripts.
What we collect
Nothing. The site runs entirely in your browser. All calculator inputs and outputs stay on your device. We do not use cookies, local storage, analytics scripts or advertising trackers.
Server logs
Our hosting provider (Cloudflare Pages) maintains standard request logs including IP address and user agent for security and abuse-prevention purposes. These logs are retained per Cloudflare's standard policies and are not used by us for any analytics.
Fonts and third-party requests
Inter and JetBrains Mono, the two fonts used across the site, are self-hosted on our own domain. Your browser never contacts Google Fonts or any other third-party font provider, and no request leaves your device to load them.
Contact data
If you email us via the contact page, we will only use your email to reply. We do not add it to any mailing list or share it with third parties.
Your rights
Because we do not collect personal data beyond standard, anonymised server logs and whatever you choose to send us by email, there is little personal data to request, correct or delete. If you have emailed us and want that message removed, tell us and we will delete it.
Changes
We will update this page if our practices ever change. There is no notification system because we do not collect contact details.
