MasteryQuiz ("the app") is a quiz-making and exam-practice app for Android. It is provided by James McCarthy, based in the United Kingdom ("we", "us"). You can contact us at MasteryQuiz26@gmail.com.
The app stores the following in the app's private storage on your phone: quiz sets you create or import, bookmarks, quiz progress, scores and attempt history, your settings, and, if you enter one, your Gemini API key. This information stays on your device. We cannot see it. Uninstalling the app deletes it. If you use "Export backup", the file you create is saved wherever you choose, and you are responsible for it.
When you import a PDF, its text is extracted on your device.
We do not run analytics, we do not use accounts, and we do not collect your name, email address or location. The only information that reaches us directly is the content of a report you choose to send (section 6).
The app can generate quiz questions in three ways. You choose which one to use in Settings.
AI-generated questions may be inaccurate or inappropriate. Please check them before relying on them, and use the report button if you see problematic content.
The app shows ads using Google AdMob: a banner on the home screen and an occasional full-screen ad after you finish a quiz. To provide and measure ads, Google may collect and use information such as your device's advertising ID, IP address, device and app information, and how you interact with ads. Google's use of this data is described in How Google uses information from sites or apps that use its services and in Google's Privacy Policy.
Where required by law (for example in the UK and European Economic Area), the app asks for your consent before showing personalised ads, using Google's consent tool. You can change your choice at any time in Settings → Privacy → Ad privacy choices where this option is shown. You can also reset your advertising ID or opt out of ad personalisation in your Android settings (Settings → Google → Ads). We do not sell your personal information.
If you tap "Report this question", the app sends us: the question text, its answer options and explanation, the reason you selected, any note you type, the quiz title, the app version, the platform (Android) and the time. We use reports to improve content filtering and moderation. Reports are delivered to us through Formspree, which acts as our processor. Please do not include personal information in the note. We keep reports for 12 months and then delete them. Our lawful basis is our legitimate interest in keeping the app safe and compliant with app store rules.
The app uses internet access (to reach AI services, show ads and send reports) and the Android advertising ID (used by AdMob, section 5). It does not request access to your contacts, camera, microphone, photos or location.
The app is not directed at children under 13 and we do not knowingly collect personal information from them.
Under UK data protection law you have rights to access, correct, delete, restrict or object to the use of personal information we hold about you, and to data portability. Because we hold almost no personal information, the practical request is usually to delete a report you sent: email us and describe it. You also have the right to complain to the Information Commissioner's Office (ico.org.uk).
Data sent from the app to AI services, ad services and our report endpoint travels over encrypted (HTTPS) connections. Data on your device is protected by your device's own security.
If we change this policy we will update the date above, and for significant changes we will tell you in the app or the store listing.
