CSQuiz is built to work without accounts and without collecting personal information. This page explains what data stays on your device, when the app needs an internet connection, and which third-party services may process limited device data.
CSQuiz is designed so that studying works without identity-based features. The app stores your attempts, bookmarks, scores, and streaks locally on your own device. We do not ask for your name, email address, or phone number, and we do not create an account behind the scenes.
CSQuiz needs an internet connection to download MCQ subjects, check for content updates, and load certain services such as advertisements. If the device stays offline for an extended period, the app may request an internet connection before continuing so it can confirm content integrity and operate correctly.
We do not collect, store, or transmit personally identifiable information. CSQuiz does not require account creation, a name, an email address, or a phone number.
On first install, the app generates an anonymous random identifier (UUID) and stores it on your device. That identifier does not contain personal information and is used only for anonymous crash reporting.
Your study progress, including answered questions, test scores, bookmarks, and daily streaks, stays exclusively on your device in encrypted local storage.
CSQuiz uses Google AdMob to display advertisements. AdMob may process your device's advertising identifier, cookies, and other device-level data to serve personalized or non-personalized ads under Google's own privacy rules.
Advertisements are not shown during the first 48 hours after installation. You can opt out of personalized advertising at any time through your device settings.
The app uses third-party services that may process limited device information under their own privacy policies:
You can review Google's privacy terms at policies.google.com/privacy.
When you download MCQ subjects, the app sends a request to our secure server with only the requested subject identifier. No personal data, device identifiers, or location data are included in that request.
Downloaded subject content is stored on your device in encrypted form. The app uses RSA key exchange and AES-256 symmetric encryption so that subject files cannot be read or extracted outside the app.
CSQuiz does not require registration or sign-in. There are no user accounts, usernames, passwords, or personal profiles associated with the app.
The following information is stored locally on your device and not sent to our servers:
You can clear your progress data, including attempts, bookmarks, and streaks, from the app's settings. To remove all locally stored data, including downloaded subject content, uninstall the app from your device.
CSQuiz is designed for students studying computer science subjects and is not directed toward children under 13. We do not knowingly collect personal information from children, and the app does not require personal information from any user.
We may update this Privacy Policy from time to time. When we do, the revised policy will be posted on this page. Continued use of the app after a published update means you accept the revised policy.
If you have questions about this Privacy Policy, contact us at nirvionlabs@gmail.com. You can also use the Send Feedback option in the CSQuiz settings menu.
