Study Guide is a study-planning app for students at universities across Nigeria, the rest of Africa, and beyond. This page explains, in plain language, what data the app touches and — just as importantly — what it doesn't.
Study Guide is built to work entirely on your device. Your study maps, exam dates, session notes, and settings are saved locally on your phone — we don't run an account system, we don't require sign-up, and we don't operate a server that collects your study data.
The app is designed around on-device storage. When you create a study map, add sessions to the custom builder, or tick off a checklist item, that information is written to your device's local app storage — it is not transmitted to Study Guide, ProfKingkeys, or any server we run.
Specifically, the app stores locally:
We do not collect your name, email, phone number, academic records, or any personally identifying information through the app itself, because there is no account or sign-up flow.
Your study data lives in the app's local storage on your device (similar to how a notes app keeps its notes). It stays there until you delete it — either by using the "Clear all history" option in Settings, or by uninstalling the app.
We cannot see, access, back up, or recover this data. If you clear it, switch phones, or uninstall the app without exporting your plans first, it's gone for good on our end too — there is no cloud copy for us to restore from.
The app requests only what it needs to function as a study planner:
| Feature | Why |
|---|---|
| Notifications | To send you study session reminders and exam alarms you schedule yourself. You can deny this and still use the app. |
| File / storage access | To save exported study-map PDFs to your device when you tap "Download." |
| Share | To let you share a study map (as text or an image) through apps already on your phone, such as WhatsApp or Telegram. This uses your device's normal share menu — we don't see what you share or who you send it to. |
Study Guide does not request camera, microphone, contacts, precise location, or call/SMS permissions, and never will without updating this policy first.
Study Guide offers an optional one-time or subscription premium unlock (for features like downloads, alarms, multi-generate, and the custom study-map builder) through Google Play Billing. Purchase transactions are processed entirely by Google — Study Guide and its developer do not receive or store your payment details (card numbers, billing address, etc.).
Google's handling of payment information is governed by the Google Privacy Policy. We only receive confirmation from Google Play that a purchase was completed, so the app can unlock premium features on your device.
Study Guide is intended for university and higher-education students generally aged 16 and above. It is not directed at young children, and we do not knowingly collect personal information from children under 13 (or the minimum age of digital consent in your country, if higher). Since the app doesn't collect personal data or require an account, there is no personal profile to create for any user regardless of age.
Because your study data stays on your device, you are already in full control of it:
If you are located in the European Economic Area (GDPR), the United Kingdom (UK GDPR), California (CCPA/CPRA), Nigeria (NDPA), or another jurisdiction with data protection laws, these local-first practices are designed to minimize what falls under those regulations in the first place — but you're welcome to contact us with any questions (see below).
Study Guide uses a small number of third-party services to function:
| Service | Purpose | Data involved |
|---|---|---|
| Google Play Billing | Processes premium purchases | Handled entirely by Google; see their privacy policy |
| Google Play Store | App distribution, installs, updates | Governed by Google Play's own privacy terms |
| Android system share sheet | Lets you share study maps to other apps | Only what you choose to share, sent directly by your device's OS |
We do not use third-party analytics SDKs, advertising networks, or trackers inside the app. No study content is sent to any third-party server by Study Guide itself.
Because your study data never leaves your device under normal use, the main security boundary is your device itself. We recommend using your phone's standard lock screen protection. If you sell, lose, or give away your device, use "Clear all history" first or perform a factory reset to remove locally stored app data.
If Study Guide's data practices change in the future (for example, if we introduce cloud sync or accounts), we will update this policy, revise the "Last updated" date at the top, and — where the change is material — provide notice inside the app before the new practices take effect.
Study Guide is built and maintained independently. For privacy questions, data requests, or general support, reach out via:
