ScanSign is an offline document scanner. Your scans, OCR text, signatures, and annotations stay on your device. We have no servers that store your data, no accounts, and no analytics SDKs.
The short version: the only data that leaves your phone is whatever you explicitly tap Share to send — and even then, it goes to whoever you sent it to (WhatsApp, Gmail, Drive, etc.), not to us. We never see it.
android.permission.CAMERAUsed only while you are inside the Scan flow. ScanSign does not run the camera in the background or capture anything outside of a tap-initiated scan. Camera frames are processed locally by Google's on-device ML Kit Document Scanner — they never reach a server.
android.permission.POST_NOTIFICATIONSUsed for in-app status messages (e.g. "PDF exported"). ScanSign sends no marketing notifications, no engagement nudges, and no third-party push.
Scanned page images, generated PDFs, OCR text, signature samples, stamps, and annotations are stored in app-private storage on your device. Other apps cannot read this data. Uninstalling ScanSign deletes everything.
ScanSign uses on-device libraries from Google for scanning and text recognition (ML Kit Document Scanner, ML Kit Text Recognition). These run locally on your phone. Google's ML Kit on-device APIs do not transmit images or text to Google's servers for these operations — see Google's ML Kit Terms of Service for the contractual commitment.
Sharing a PDF, image, or signed document opens Android's system share sheet. ScanSign hands the file over to the app you pick (WhatsApp, Gmail, Drive, etc.). At that point the file is governed by the privacy policy of the receiving app — we cannot see, log, or recall what you sent.
ScanSign is a general-audience document tool. It contains no advertising, no chat features, no user accounts, and no user-to-user contact. There is no profiling of children or anyone else. We do not knowingly collect data from children under 13 because we do not collect data at all.
Documents and signatures are stored in app-private storage, which Android isolates from other apps. PDF password protection (when used on export) applies AES-256 encryption via PDFBox-Android.
If we ever add a feature that changes what data the app touches — for example, an optional cloud-sync mode in a future version — this page will be updated before that version ships, and the affected feature will be opt-in only.
