How can we help?

DocuScanr uses multiple layers of encryption to protect your documents. All scanned document data is encrypted using AES-256-GCM via Google's Tink cryptographic library. This is the same encryption standard used by governments and financial institutions worldwide.

Document metadata and information are stored in a SQLCipher encrypted database. All encryption keys are managed by the Android Keystore, a hardware-backed secure enclave on your device that prevents key extraction. Together, these layers ensure your documents are fully 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 includes everything you need for basic document scanning:

Scanning: Single-page document scanning with AI-powered edge detection and perspective correction.

Filters: Three image filters (Original, Auto Enhance, and Grayscale).

Security: Full AES-256-GCM encryption, app lock with biometric or PIN, recovery key, and encrypted backup.

Management: Document rename, delete, search, page reorder, page delete, and page rotate.

Export: PDF export with configurable page sizes.

New users automatically receive a 7-day free trial of all Pro features. During the trial, you get access to multi-page documents, all image filters, gallery and file import, OCR text recognition, PDF annotations and signatures, folders, and watermarks.

No credit card is required to start the trial. When the trial ends, you can continue using the free version or upgrade to Pro with a one-time purchase through Google Play. Pricing varies by region. There are no subscriptions and no recurring fees.

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 DocuScanr requests. It is needed to scan documents using your device's camera.

DocuScanr does not request access to your contacts, location, microphone, phone state, storage (beyond its own app-scoped directory), or any other sensitive permissions. We believe in requesting only the absolute minimum permissions needed to function.

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.
