The Scanner That Never Sees Your Documents
Most scanner apps upload your files to their servers. ScanFlow doesn't. Everything stays on your device, under your control.
Zero Server Storage
ScanFlow has no document servers. Your scans are never uploaded to, processed on, or stored on any ScanFlow infrastructure.
No Account Required
Use every feature without creating an account or providing personal information. No email, no phone number, no sign-up.
Fully Offline
Scanning, OCR, signing, organizing, and exporting all work without an internet connection. Airplane mode? No problem.
EU-Based Company
ScanFlow is developed in Podgorica, Montenegro. We follow EU privacy standards and GDPR principles by design.
Your Own Cloud
Cloud backup goes directly to your personal iCloud, Google Drive, Dropbox, or OneDrive. We are never the middleman.
No Data Selling
We don't collect, analyze, or sell your data. Our business model is selling the app, not selling you.

How It Works, Technically
When you scan a document with ScanFlow, the entire pipeline runs on your device's hardware. The camera feed is processed locally using Apple's Vision framework (iOS) or Android's CameraX and ML Kit. Edge detection, perspective correction, and image enhancement are all computed on-device using the phone's neural engine.
OCR text recognition also runs locally. On iOS, ScanFlow leverages the built-in Vision framework for text recognition. On Android, it uses on-device ML models. No images or text are sent to any external service for processing.
When you choose to back up your documents, ScanFlow connects directly to your cloud storage provider using their official APIs. Files are transferred from your device to your cloud account. ScanFlow acts as a conduit, not a destination. We never receive, cache, or inspect your files during this process.
The app collects only minimal, anonymous analytics (such as which features are used most) to improve the product. These analytics contain no document content, no file names, and no personally identifiable information. You can opt out of even this minimal analytics in Settings.
