1. Summary
ScanOnce is built around a simple principle: your scanned documents should stay on your device unless you choose to share or export them.
All scanning, edge cropping, PDF generation, PDF preview, and document management operations are performed locally on your device. ScanOnce does not send documents to developer-operated servers for processing.
- No account, login, or registration is required.
- ScanOnce does not upload your PDFs, images, folders, tags, or settings to a ScanOnce server.
- ScanOnce does not use analytics SDKs, advertising SDKs, AI processing services, or tracking technologies.
- Documents may leave your device only when you use iOS sharing, AirDrop, Files, Mail, iCloud Drive, or another destination that you choose.
1.1 Data Collection Notice
ScanOnce does not collect, store, sell, or share any personal information.
ScanOnce does not create user accounts, build user profiles, or upload documents to developer-operated servers.
All scanning, PDF generation, PDF preview, folder management, tag management, and document organization operations are completed locally on the device.
ScanOnce is designed to let users fully control their own documents.
Unless users actively export, share, or move files to other services, documents do not leave the device.
2. Data We Handle
ScanOnce handles the content and metadata needed to provide local document scanning and management features.
| Data | Purpose | Where It Is Stored |
|---|---|---|
| Scanned pages and imported images | To create local PDF documents. | On your device. |
| PDF files and thumbnails | To display, preview, manage, and share documents. | In the app's local storage directory. |
| Document metadata | To show filename, creation date, modified date, page count, file size, folder, favorite status, and tags. | In local app data storage. |
| Folders and tags | To organize and search your local documents. | In local app data storage. |
| Settings | To remember appearance, Face ID protection, and auto-lock preferences. | On your device. |
3. Permissions
Camera
ScanOnce requests camera access only when you start document scanning. The camera is used through Apple's VisionKit document scanner to capture pages and create local PDFs.
Face ID or Device Passcode
If you enable Face ID protection, ScanOnce uses Apple's LocalAuthentication framework to verify you. ScanOnce does not receive, access, or store any Face ID data, biometric data, or device passcode. Authentication is handled entirely by iOS.
Files, Photos, and Share Extension
When you import a PDF from Files or share an image/PDF into ScanOnce from another app, ScanOnce receives only the items you selected. It does not browse your full photo library or file system.
ScanOnce only accesses files or images that you explicitly choose to import. ScanOnce does not scan, index, or read your full photo library, file system, or other content that you have not actively selected. ScanOnce only accesses the files or images necessary to complete the import process.
4. Local Storage
ScanOnce stores PDFs, thumbnails, folders, tags, and settings locally on your device. The app does not maintain a ScanOnce cloud account and does not sync documents to a ScanOnce service.
If you use iOS device backups, iCloud Drive, Files, Mail, AirDrop, or another third-party app, those services are controlled by Apple or the relevant third party, not by ScanOnce.
6. Security
ScanOnce supports Face ID or device passcode protection and configurable auto-lock timing. These features are intended to reduce casual access to your local documents.
No security measure is perfect. You are responsible for protecting your device, device passcode, backups, exported files, and any destination where you choose to share documents.
6.1 Diagnostics
The current version of ScanOnce does not collect crash logs, analytics data, or diagnostic information.
7. Children
ScanOnce is a general-purpose local document scanning tool. It does not knowingly collect personal information from children or operate any child-directed backend service.
8. Changes to This Policy
We may update this Privacy Policy when ScanOnce changes. If ScanOnce's privacy practices change materially, this Privacy Policy will be updated accordingly.
9. Contact
If you contact support, you may choose to send diagnostic details, screenshots, or other information by email. That information is provided voluntarily by you and is handled through your email provider.
We will respond to privacy-related questions or support requests within a reasonable time.
