On-Device Vault.
Total Ownership.
Your Papers Stay on Your Phone.

Camera Scan & Import

Document scanning with automatic cropping, single or multi-page. Import existing PDFs or page photos — or create a manual record with no files at all.

# vault intake pipeline — all local
SCAN camera -> auto-crop -> page-01..n
IMPORT *.pdf / *.jpg via system picker
MANUAL title + dates, zero files
network calls during scan/import: 0

Autonomous Expiration Radar

Optional dates per document. An Expiring view sorted nearest-first, plus on-device alarms and notifications before deadlines — rescheduled after reboot.

App-Private Storage Guarantee

Scans and PDFs live in the Android app sandbox. System backup and device-transfer rules exclude the vault, so documents never leave the phone unless you tap Share or Export.

<!-- AndroidManifest.xml (excerpt) -->
allowBackup="false"
dataExtractionRules="@xml/data_extraction_rules"
fullBackupContent="@xml/backup_rules"
# FileProvider: you approve every share/export

Declared Permissions, Nothing Hidden

No root, no device-admin, no special access. Every permission exists for one visible feature — and optional ones degrade gracefully when denied.

# why each permission exists
NOTIFICATIONS  expiry reminders you configure
EXACT_ALARM    precise timing (+inexact fallback)
BOOT_COMPLETED re-arm alarms after reboot
VIBRATE        notification haptics
NETWORK_STATE  connectivity check before sync
INTERNET       app services + policy page — vault docs never upload
