Privacy Policy
Simple PDF Viewer · last updated
1. Summary
Simple PDF Viewer (“the app”) is an offline PDF reader published by Cool App Helpdesk.
- The app collects no personal data and operates no servers.
- The app does not request the
INTERNETpermission and makes no network connections. - PDFs are opened and rendered entirely on-device. The app contains no advertising, no analytics, and no third-party tracking SDKs.
2. Data we collect
None. The developer does not collect personal data, telemetry, identifiers, device information, IP addresses, advertising IDs, or usage analytics. There are no user accounts and the developer operates no servers that the app communicates with.
3. Data stored on your device
| Item | Where | Sent off device? |
|---|---|---|
| List of PDF files you have opened (path, name, last-opened time) | App-private Room database | Never |
| Rendered page thumbnails (cache) | App-private cache | Never |
| App preferences (theme, last viewed page) | App-private DataStore | Never |
The PDF files themselves are stored wherever you put them on your device; the app only reads them.
4. Permissions used
| Permission | Reason |
|---|---|
READ_EXTERNAL_STORAGE (Android 10 and earlier) | Open PDF files stored in shared storage on older Android versions. Not requested on Android 11+, which uses the Storage Access Framework instead. |
MANAGE_EXTERNAL_STORAGE | Browse PDF files across your device’s shared storage. You explicitly grant this permission in system settings; the app cannot enable it on its own. |
The app does not request INTERNET, location, contacts, microphone, camera, phone state, or any other sensitive permission.
5. Network activity and third parties
The app does not request the INTERNET permission, so the operating system prevents it from making any network connection. PDF parsing is performed locally using the open-source PdfBox-Android library. The app contains no advertising SDKs, no analytics SDKs, no crash-reporting SDKs, and no social or attribution SDKs.
6. Children’s privacy
The app is intended for general audiences and is not directed at children under 13. The developer does not knowingly collect personal information from children — and, as noted above, no information is collected from anyone.
7. Data retention and deletion
The recent-files list, thumbnail cache, and preferences remain on your device until you clear them inside the app, clear the app’s storage in Android Settings → Apps → Simple PDF Viewer → Storage, or uninstall the app. The app does not delete the PDF files themselves.
8. Security
The app holds no personal data and makes no network requests, so the privacy attack surface is essentially zero. App data is held in the app’s private storage, protected by Android’s built-in application sandboxing. The app is distributed through the Google Play Store, which verifies the developer signing key on every update.
9. Changes to this policy
If any material aspect of how the app handles data ever changes, this page will be updated and the “last updated” date above will be bumped. Continued use after a change constitutes acceptance.
