SeliaScan is the new product name for ScanIt. The Android package and existing repository URLs remain unchanged for update and purchase continuity.
Scan → save → share.
A deliberately simple Android document scanner for people who do not want to manage files.
This patch synchronizes versions with the Play edition. Public functionality is unchanged from 1.8.0; the Play-only subscription controls are not part of this app.
The stable GitHub edition is fully open source under the MIT License. It has no ads, consent flow, Billing, Premium tier, paywall, or feature locks. Every scan, signing, file-editing, cleanup, OCR, redaction, and Document Action feature is available immediately. Buy Me a Coffee remains an optional donation and does not change app functionality.
This release accepts high-resolution scanner pages in OCR, barcode detection, Safe Share, and orientation analysis while keeping decoded bitmaps bounded. It also reduces Manual cleanup memory use, preserves selected-folder automatic PDF saving, hardens durable settings checkpoints, improves large-text accessibility, and updates the Android build toolchain.
Manual redaction now defaults to a professional straight-line tool and keeps the freehand brush as an option. Both share adjustable thickness, undo, redo, clear, and permanent rasterization into a protected child revision.
Document Actions now recognize Latin text, including Czech, or Chinese text. Read all pages can use Auto, Czech, English, German, Spanish, or Chinese speech. Settings are grouped into collapsible General, Saving, Scanning, Sharing, and Advanced sections; action-language controls live under Advanced.
Manual redaction now works like a black marker: draw directly over text, adjust the brush thickness, and use undo, redo, or clear. Applying the redaction burns the black strokes into a protected child revision, so the covered pixels cannot be moved or removed from that result.
The current stable release keeps the full Google scan editor with page previews, crop and rotate, and Google's filter gallery, then continues directly to the SeliaScan Result and sharing actions. The redundant intensity/shadow screen has been removed. The APK also includes the Recent scans dashboard, reusable visual signatures and stamps, measured and custom PDF size targets, and six selectable language modes. Settings now include a localized Buy Me a Coffee button; support remains optional and does not unlock features. Settings now save after each change and survive navigation and updates. Shared files stay saved; delete exact copies explicitly from Recent scans. Visual signatures and stamps can be moved directly on a larger preview, resized and rotated with gestures, or fine-tuned from the collapsed Manual position panel. SeliaScan supports Android 10 and newer while keeping the same Google scanner, sharing, saving, and verified cleanup behavior.
SeliaScan corrects page orientation only when recognized text provides reliable line-angle evidence. Ambiguous and textless pages keep the scanner orientation. Document Actions also contain local Smart cleanup and Manual cleanup. Smart cleanup improves paper contrast and removes likely edge fingers; Manual cleanup replaces user-drawn spots with the surrounding paper color. Both create reversible child revisions.
The Result screen now keeps the document preview prominent and opens a full-screen zoomable viewer when tapped. File details can change a document's PDF name, size, and folder, and can change its image name, size, format, and folder. Image exports support exact Original files, high-quality JPEG, and lossless PNG. A Recent scan opens directly when tapped. The stable Actions panel extracts Latin-script text from all pages, exports it through Android's file picker, or detects QR codes and barcodes on the current page using on-device ML Kit models delivered by Google Play services. The recognition model may download before its first use; Actions report that state and can be retried afterward.
Result pages now swipe horizontally and reveal the edge of the next page. Rescan, Sign / stamp, and Actions are compact accessible buttons, while File details groups PDF and image changes into compact Size, Format, and Location controls. Externally deleted PDF and image outputs are shown as Deleted and can be recreated directly with Save without reusing stale provider locations. After a full app restart, SeliaScan opens a fresh scanner session instead of reopening the previously viewed Result; completed scans remain available from Recent.

Sending a scanned document should not require understanding folders, file managers, or export dialogs. Open SeliaScan and the scanner starts. Capture one or more pages, check the result, then share the PDF or images through Android.
The interface is monochrome and follows the system language by default. English, Czech, German, Spanish, and Simplified Chinese can also be selected from one compact language picker in Settings.
SeliaScan was built with AI-assisted coding and design. The maintainer reviews the source, release artifacts, and real-device workflows.
- Opens Google ML Kit Document Scanner directly; no redundant landing-page tap.
- Automatic capture, edge detection, crop, rotation, filters, shadow removal, and cleanup through the ML Kit scanner flow.
- Single-page and multi-page PDF/JPEG output.
- Lazy page thumbnails for browsing multi-page results without decoding every page at once.
- Google's review editor provides page previews, crop and rotate, and Original, Auto, Color, Grayscale, Black and white, and Shadows filters before SeliaScan creates the result.
- Automatic orientation correction from reliable text-line angles; ambiguous pages keep the scanner orientation.
- Measured PDF size goals of Original, 200 KB, 500 KB, 1 MB, 5 MB, 10 MB, 20 MB, or a custom 1 KB–500 MB target; SeliaScan reports the actual size when a readable result cannot meet the selected goal.
- Recent scans dashboard for up to eight bounded temporary working copies.
- Automatic PDF and Gallery saving, each configurable in Settings.
- Manual PDF, image, or combined saving from File details.
- Per-document PDF size and folder changes without changing saved defaults.
- Per-document image size, format, and folder changes with exact Original, high-quality JPEG, and lossless PNG export.

- On-device Latin-script text extraction across all pages, explicit text export, and selected-page QR/barcode detection with selectable results.
- Local Smart cleanup and lasso-based Manual cleanup with a preserved parent revision.
- Optional PDF destination selected with Android's Storage Access Framework.
- PDF/image sharing with configurable email subject and message.
- Exact deletion of saved PDFs or Gallery images from Recent scans after explicit confirmation.

The scanner processes document content on-device. SeliaScan keeps at most eight temporary scan directories for Result and Recent scans. Android may clear these working copies. PDFs saved to Downloads or a selected folder and images saved to Gallery remain until the user deletes them.
- Ordinary scanning, OCR, barcode detection, redaction, and file creation remain on-device.
- Smart cleanup and Manual cleanup process document pixels locally and preserve the parent revision.
- Google Play services and ML Kit may process diagnostic and usage telemetry; scanned input remains on-device according to Google's ML Kit documentation.
- SeliaScan does not send scanned content to a maintainer-operated server.
- File sharing uses scoped content URIs with read access granted to the selected receiving app.
- Saved-output changes are verified before activation and remove only the exact previously tracked output.
- Copied OCR and barcode results are marked as sensitive; detected payloads never open automatically.
- Android backup and device transfer are disabled for SeliaScan app data.
- Sharing and printing hand a user-selected document to another app or service under that recipient's terms.

- Android decides which compatible apps appear in the Sharesheet.
- Recent scans are temporary working copies, not a permanent document library.
- Automatic orientation changes require reliable text-line evidence; use the Google review editor for ambiguous pages.
- Android 17 has no
maxSdkrestriction but has not yet been device-tested. - Google Play publication is still in testing; do not describe the app as a production Play release yet.
- Visual marks do not verify identity, authorization, or document integrity.
- The repository does not contain production signing material.
