Privacy

This app does not create accounts and does not collect personal data. Your language, progress, mistakes, unlock status and licence key are stored only in your browser on your own device (local storage). No cookies, no advertising trackers.

Anonymous usage statistics. To fix problems and improve the questions, the app sends anonymous events to our own server: which pages and chapters are opened, practice-exam scores, how often each question is answered right or wrong, technical error messages, the referring website, the country (from the network, not your location) and whether the device is a phone. No name, e-mail, IP address or device identifier is stored; a random code that lives only while the page is open groups the events of one visit. If your browser sends "Do Not Track", nothing is sent.

Feedback and reports. If you use "Feedback" or "Report a problem", the text you write is stored with the language (and the question number, for reports), your browser type and whether the app is unlocked. You may leave an e-mail address if you want a reply; it is used only to answer you and deleted when the matter is closed. Please do not include other personal information.

Licence keys. When you activate, the key is sent to our verification service, which checks it with Gumroad (the shop that processed your payment) and returns only "valid" or "not valid". An unlocked device re-checks the key about once a week, so that refunded keys stop working. Payments are handled entirely by Gumroad under its own privacy policy.

Questa app non raccoglie dati personali. Invia solo statistiche anonime d'uso (pagine aperte, risposte giuste/sbagliate per domanda, errori tecnici, paese), senza indirizzo IP né identificativi del dispositivo; con "Do Not Track" non invia nulla. La chiave di licenza viene inviata solo per la verifica con Gumroad.
