Privacy-focused document scanner with OCR and PDF export
About this app
MakeACopy is an open-source document scanner app for Android that allows you to digitize paper documents with offline OCR functionality. The app is privacy-friendly and works completely offline — no cloud connection, no tracking.
Features: • Camera scanning: Capture documents using your device’s camera • Edge detection: Automatic document boundary detection using OpenCV, enhanced by a custom-trained ONNX inference model • Perspective correction: Manually or automatically adjust document perspective • Grayscale export: Optional grayscale filter applied during PDF creation • OCR: Offline text recognition using PaddleOCR in the published paddle flavor • PDF export: Save scanned documents as searchable PDFs • Share & save: Export locally or share via other apps • Dark mode: System-based Material 3 theme with light and dark appearance • Privacy-focused: Fully offline — no data leaves your device
The F-Droid and Google Play listings provide the paddle flavor with PaddleOCR. The standard flavor with Tesseract remains available through GitHub Releases for users who still need Tesseract language data or workflows.
MakeACopy is F-Droid compliant and builds native libraries from source during the build process, ensuring that no prebuilt binaries are included in the repository. All components are open source and respect your privacy.

Installation Guide
Open Settings on your Android device
Go to Security → Unknown sources (or Install unknown apps)
Enable "Allow from this source" for your browser or file manager
Open the downloaded APK file from your Downloads folder
Tap "Install" and wait for installation to complete
Launch the app from your home screen
Make sure to re-enable Unknown Sources restrictions after installation for security.
How to install this safely
How to verify the file you downloaded
Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.
What the signing certificate proves
Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be de.schliweb.makeacopy is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.
How to roll back to an earlier version
If the current release misbehaves, 4.6.1 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall MakeACopy first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.
Why we list sources instead of hosting everything
The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of MakeACopy, and a listing is removed when the evidence for it stops holding up.
