Cookies and local storage
Last updated: 16 August 2026
Cookies are small files that a browser sends back to a server with every request. Local storage is different: it stays in your browser and is never attached to requests unless the site deliberately reads it and sends something.
AirportDoku sets no cookies of its own, and loads no advertising or third-party tracking tools that would require consent. Everything the game remembers is kept in local storage.
Local storage holds:
- your current grid, flight time, guesses and completion state, per cabin and puzzle;
- your streaks, past completions and Flight Log progress;
- your last selected cabin;
- one randomly generated anonymous installation identifier, used for privacy-minimised first-party analytics only — never for issue reports. The server keeps only a hashed form of it.
The analytics described on the Privacy page are first-party, carry no answer or search content, and are not used to profile you or follow you across other sites, so no consent banner is shown. If a third-party tool that requires consent is ever added, this page will be updated and consent will be requested before it loads.
Hosting and security infrastructure may use strictly necessary technical mechanisms to serve and protect the site.
You can clear local storage at any time through your browser's site data settings. Doing so resets your progress, streaks and the anonymous identifier. For privacy or cookie questions, email privacy@airportdoku.com.
