This Privacy Policy outlines our policies regarding the collection, use, and disclosure of personal information when you use our Service and informs you about your privacy rights.
Information We Collect
We do NOT collect, store, or share any personal information. Our app is designed to work completely offline, and all data generated by your use of the app stays locally on your device. What We Do NOT Collect: • No name, email address, phone number, or physical address • No account creation or login required • No tracking or analytics tools • No cookies or tracking technologies • No IP addresses or device identifiers • No location data • No contacts or photo access What Is Stored Locally on Your Device: All data generated by your use of the app remains solely on your device and is never transmitted to us. This includes: • Study progress and quiz scores • Bookmarked questions and saved answers • App preferences (dark mode, notifications, etc.) • Practice test history • Downloaded question banks We never have access to this data. It remains completely under your control and is permanently deleted when you uninstall the app.
How We Use Your Information
Since we do not collect any personal data, there is no personal information to use, process, or share. Your study progress, quiz scores, preferences, and all other data generated within the app are stored exclusively on your device and are used solely for your own learning experience. We do not: • Sell, rent, or share any personal information with third parties • Use your data for marketing or advertising purposes • Track your activity across other apps or websites • Send promotional emails or newsletters The only data processing that occurs is: • License verification via Firebase (device identifier only) • App update checks via GitHub (no personal data collected) Neither of these processes collects or stores personal information. All communications are secure and limited to essential functionality.
Data Retention
Since we do not collect any personal data, there is no personal information to retain. All user data — including study progress, quiz scores, bookmarks, preferences, and downloaded question banks — is stored locally on your device and remains under your control. This data stays on your device until you choose to: • Delete it by uninstalling the app • Reset your progress within the app settings Once you uninstall the app, all locally stored data is permanently removed from your device. We do not have access to this data at any time. For license verification records, device identifiers are used solely for activation purposes and are not stored or retained by us after verification is complete.
Transfer of Data
Since we do not collect, store, or process any personal data, there is no personal information to transfer to any location. All user data — including study progress, quiz scores, and preferences — remains stored locally on your device and is never transmitted to our servers or any third party. The only external communications that occur are: • License verification: A device identifier is sent to Firebase (Google servers) solely for activation purposes. No personal data is transmitted. • App update checks: The app checks GitHub for version information. No personal data is transmitted. Both communications are secure, encrypted, and limited to essential functionality. No personal information is stored or retained by us or any third party. If you are located outside Nigeria, your data stays on your device and is subject to your local data protection laws.
Disclosure of Data
Since we do not collect, store, or share any personal data, there is no personal information to disclose to third parties, business partners, or legal authorities. However, in the event of a business transaction such as a merger, acquisition, or asset sale, we will notify you through the app or our website if any changes occur to our data handling practices. For legal compliance or to protect our rights, we may be required to disclose non-personal, aggregated, or anonymized information, but we do not possess any personal data to share with legal authorities. All user-generated data (study progress, scores, preferences) remains stored locally on your device and is never shared, sold, or disclosed to any third party.
Security of Data
Your privacy and data security are important to us. Since we do not collect, store, or transmit any personal data, there is no risk of your personal information being intercepted, leaked, or misused. All data generated by your use of the app — including study progress, quiz scores, bookmarks, and preferences — is stored locally on your device and never transmitted to our servers. You are responsible for maintaining the security of your device, including using screen locks, biometric authentication, and keeping your device software up to date. We implement industry-standard security practices, including encrypted communications for license verification and app update checks. However, since no personal data is collected, there is nothing to compromise. If you have any concerns about data security on your device, we recommend reviewing your device manufacturer's security guidelines.

We do not control the content, privacy policies, or practices of any third-party sites or services. We strongly advise you to review the Privacy Policy and terms of any third-party website you visit. However, we do not share any personal data with these third parties, and no personal information is transmitted through these links.
