1. Introduction
Nexu App Studio ("we", "us", "our") operates the Nexu Scanner Android application (the "App"). This Privacy Policy explains how the App handles information when you use it. The App is available to general audiences and is not specifically directed toward children.
We are committed to transparency. The core design principle of the App is that your documents, images, scans, and QR history are processed and stored locally on your own device. The App does not upload your content to our servers.
We encourage you to review this Privacy Policy before using the App.
2. App Overview
Nexu Scanner provides the following on-device functionality:
- Document scanning using your device's camera
- Image-to-PDF conversion and PDF creation
- OCR (Optical Character Recognition) to extract text from images
- QR code / barcode scanning and scan history
- File management for scanned images and PDF documents on your device
- Image viewing and basic document tools
All scanning, OCR, and file-processing features are performed locally on your device. Based on a technical audit of the application, no third-party analytics, advertising, or tracking SDKs are integrated into the App.
Certain scanning features use Google ML Kit components that support on-device processing where applicable. The exact behavior and processing capabilities may depend on the relevant Google ML Kit component version and device configuration. Certain scanning and OCR features also use AndroidX CameraX. These are on-device processing components, not advertising, analytics, or crash-reporting SDKs. Based on the audit evidence, the App does not transmit user content to any server.
3. Information We Process
3.1 Data You Provide Through App Features (Processed and Stored Locally)
| Data Type | How It Is Used | Where It Is Stored |
|---|---|---|
| Camera images | When you use the camera to scan a document or a QR/barcode, the camera feed is processed in real time to detect and capture content. | On your device |
| Images and photos | If you import an image from your gallery, it is processed locally for scanning, OCR, or PDF creation. | On your device |
| Files and documents | The App creates and stores scanned images and PDF documents at your direction (e.g., saving a scan or generating a PDF). | On your device |
| QR/barcode scan history | When you scan a QR code or barcode, the scanned content may be saved in the App's on-device database so you can view or reuse it later. Scanned content can include text, URLs, WiFi network details, or other data encoded in the code. | On your device (app-local database) |
| App preferences and settings | Basic in-app settings (e.g., default naming, display preferences) are remembered so your preferences persist between sessions. | On your device |
3.2 Data We Do NOT Collect
The App does not collect or access:
- Account registration information (no account is required)
- Your name, email address, or phone number
- Precise or approximate location
- Contacts, calendar, or messages
- Payment or financial information
- Device identifiers (e.g., IMEI) or advertising IDs
- Web browsing history
- Analytics or crash-reporting data (no analytics SDKs are integrated)
4. How We Use Information
Information processed by the App is used solely for core application functionality:
- Providing document scanning, OCR, image-to-PDF, QR/barcode scanning, and file-management features.
- Saving your scans and QR history locally so you can access them later.
- Remembering your in-app preferences.
We do not use your data for advertising, profiling, or marketing.
5. Permissions and Their Purpose
The App requests the following permissions, used only for the purposes described:
| Permission | Purpose | Notes |
|---|---|---|
| Camera | To scan documents, QR codes, and barcodes using your device's camera. | Requested only when you use a scanning feature. |
| Storage (write external storage) | To save scanned images and PDF documents to your device on legacy Android versions (Android 9 / API 28 and earlier). | On newer Android versions, the App uses modern scoped/app-specific storage. |
| Network state / Wi-Fi state | To check network connectivity and to support WiFi network QR codes so you can connect to a network you have scanned. | These permissions do not enable transmission of your content. |
6. Data Storage and Security
- All App data (scanned images, PDFs, QR history, and settings) is stored locally on your device.
- Data is held in the App's on-device database, preferences, and file storage.
- The App does not use third-party analytics, advertising, or tracking SDKs.
- The App does not upload your documents, images, scans, or QR history to Nexu App Studio servers. When you choose to open an external link or use an external sharing feature, the selected website or application may handle the information according to its own privacy practices.
- While we implement reasonable safeguards and rely on your device's built-in protections, no method of storage or transmission is 100% secure. You are responsible for protecting access to your device.
7. Data Sharing and Disclosure
- We do not sell, rent, or share your personal data with third parties.
- The App does not upload your documents, images, or QR history to any server.
- User-initiated sharing: When you use the Android share sheet to share or export a file to another app, the file is provided directly from your device to the app you choose. That app's own privacy practices then apply.
- External links: If you scan a QR code that contains a URL and choose to open it in a browser, the privacy practices of that website will apply.
8. Data Retention and Deletion
- In-app deletion: You can delete individual files and scans, and clear your QR scan history using the delete options available within the App.
- Clear data: You can clear all App data through your device settings (Settings → Apps → Nexu Scanner → Storage → Clear data).
- Uninstall: Uninstalling the App removes the data it stores locally on your device.
9. Children's Privacy
The App is a general-audience tool and is not directed at children under 13. We do not knowingly collect personal information from children.
10. Third-Party Links
The App may contain links to third-party websites (for example, the Google Play listing). This Privacy Policy does not apply to those external websites. We encourage you to review the privacy policies of any third-party sites you visit.
11. Changes to This Privacy Policy
We may update this Privacy Policy from time to time to reflect changes in the App or applicable requirements. Updates will be posted at:
The "Last Updated" date at the top of this page reflects the most recent revision. We encourage you to review this page periodically for the latest information.
