Privacy Policy
The short version
ENO-QUIZ collects no personal data. There are no accounts, no analytics, no advertising, no cookies, and no tracking of any kind. Nothing you do in the app is transmitted anywhere.
What the app stores, and where
Your quiz progress (scores per topic, play counts, and track waitlist taps) is saved in your browser's localStorage, on your device only. This data never leaves your device, is not readable by us or by anyone else, and is deleted if you clear the app's site data or uninstall the app.
Network use
The app is a static bundle of files. After the first load it works fully offline via a service worker cache. The only network requests it makes are to fetch its own files and updates from the hosting server; no request carries any personal or behavioral data. Citation links open official regulators' websites in your browser — those sites have their own privacy policies.
Third parties
No third-party SDKs, fonts, scripts, or beacons are embedded. No data is shared with anyone, because none is collected.
Children
The app is educational content about wine regulations and collects no data from any user, of any age.
Changes and contact
If this policy ever changes (for example, if optional accounts are introduced), the new version will be published at this address with a new effective date before taking effect. Questions: contact the developer via the project page linked in the app store listing.
