Frequently Asked Questions
Quick answers to the most common questions about DocuScanr.
DocuScanr uses multiple layers of encryption to protect your documents. All scanned document data is encrypted using AES-256-GCM, the authenticated-encryption standard specified in NIST SP 800-38D. We implement it via Google's Tink cryptographic library.
Document metadata is stored in a SQLCipher encrypted database. Encryption keys are managed by the Android Keystore, a hardware-backed secure enclave on your device that prevents key extraction. Together, these layers keep your documents protected at rest.
No. Everything in DocuScanr happens entirely on your device. Document scanning, image processing, OCR text recognition, encryption, and storage are all performed locally. There are no cloud servers, no remote uploads, and no syncing to external services.
The only time data leaves your device is if you explicitly choose to share or export a document yourself (for example, sending a PDF via email). DocuScanr will never transmit your data on its own.
DocuScanr provides two safeguards that work together: a recovery key and encrypted backup files. You need both to restore your documents on a new device.
The recovery key alone does not restore your documents. Its purpose is to decrypt your encrypted backup files. Without a backup file, the recovery key has nothing to decrypt. Likewise, without the recovery key, a backup file cannot be opened.
Here is how the process works: you create an encrypted backup file from within the app and store it somewhere safe (external storage, another device, or a cloud drive you control). If you ever lose your device or need to reinstall, you restore that backup file on your new device and use your recovery key to decrypt it.
Important: If you lose your device and have no backup file, your documents are gone, even if you have a recovery key. The recovery key cannot retrieve data from a lost device.
Our recommendation: regularly create encrypted backups and store them in a safe location. Keep your recovery key in a separate secure place, such as a password manager.
The free version of DocuScanr is a full daily-driver scanner, not a stripped-down preview:
Scanning: Multi-page document scanning with ML-powered edge detection and perspective correction, plus single-pick gallery and file import.
Filters: Four image filters (Original, Auto Enhance, Grayscale, Color).
OCR: On-device text recognition with copy and in-document search.
Security: AES-256-GCM encryption, app lock with biometric or PIN, recovery key, encrypted backup, and sensitive content detection.
Management: Folders, document rename, delete, search, plus page reorder, delete, and rotate.
Export: PDF, JPEG, and PNG export with configurable PDF page sizes.
Pro is a one-time $4.99 purchase that adds workflow features on top of the free tier:
Capture: Batch import with multi-pick gallery and rapid-capture camera, plus the B&W (Sauvola) filter for crisp document binarization.
Markup: Annotations and signatures (8 tools including redact), and per-document watermarks for PDF and image export.
Organization: Many-to-many color-coded tags with cross-folder filtering.
OCR power-tools: Auto-OCR on every save, library-wide content search across every document, and OCR text export as plain text files.
Export: Password-protected export (native AES-256 PDF encryption for PDFs, encrypted ZIP for images and text).
No subscriptions, no recurring fees, no account required. One purchase, owned forever.
All purchases are processed through Google Play. To request a refund, you can use Google Play's standard refund process:
1. Open the Google Play Store app on your device.
2. Tap your profile icon, then tap "Payments & subscriptions."
3. Tap "Budget & order history."
4. Find the DocuScanr purchase and tap "Request a refund."
Google Play typically processes refund requests within 48 hours.
Camera is the only permission we prompt you to approve. It's needed to scan documents using your device's camera.
Android also auto-grants a small set of install-time permissions that don't require your approval. We want to be transparent about what they are and why we have them:
We do not request contacts, location, microphone, SMS, phone state, or storage beyond our own app-scoped directory.
No. Crash reporting is completely optional and disabled by default.
DocuScanr uses Sentry for crash reporting, but only if you explicitly opt in through the app's settings. When disabled, no crash data or diagnostic information is transmitted from your device. When enabled, only technical crash data is sent (stack traces, device model, OS version). No document content or personal information is ever included in crash reports.
