Privacy
Debrief is a personal, non-commercial project. It collects as little as possible — in fact, nothing — so this page is short.
What we collect
Nothing. There is no account, no sign-up, no email, and no analytics. Your flight file is read and analyzed entirely in your browser and is never uploaded — there is no server to upload it to. Debrief is a static site.
What lives on your device
A few things are saved locally so the tool is pleasant to use, and they never leave your browser:
- Recent flights — kept in your browser's local database (IndexedDB) so you can reopen a file without choosing it again.
- Your theme and units — a small local-storage value remembering light/dark and feet/metres.
Clearing your browser data (or using the “clear” control on the recents list) removes all of it.
Share links
When you create a share link, the flight is compressed and packed into the part of the URL after the # (the fragment). Browsers never send the fragment to a server, so the flight still isn't uploaded — the link works because whoever opens it decodes it in their own browser. Treat a share link like the file itself: only send it to people you'd give the flight to.
Hosting
The site is served as static files by Cloudflare Pages. Like any web host, Cloudflare may keep standard, short-lived request logs (such as IP addresses) for delivering and protecting the site. That's infrastructure-level and applies to fetching the page — it never includes your flight data, which stays in your browser.
What we don't do
- No tracking pixels, advertising, or third-party analytics.
- No cookies beyond the local theme/units preference described above.
- No selling, renting, or sharing of anything — there is nothing to share.
