Life Vault.
Your life. Secured.
The documents you keep. The cards you carry. The details you need.
A personal vault that brings them together on your Android phone.
QUANTUM BIT DYNAMICS / LIFE VAULT01 / YOUR EVERYDAY RECORDS
A place for the details
that matter.
Life Vault is a native Android application for keeping personal records and their attachments together. Store the information once, find it in your vault, and carry an encrypted backup you control.
Cards, front to back
Keep card information and both sides together in one entry. Recognition checks card-number validity before suggesting a value; security codes have no dedicated storage field.
Assets & warranties
Capture warranty documents and fill supported fields such as manufacturer, model, serial number, amount and expiry from recognized text.
More of your daily life
Separate areas for passwords, authenticator codes, subscriptions and private media. The local assistant provides metadata search; it is not an AI language model.
Local protection
Records and scan attachments use AES-256-GCM encryption. Unlock combines enrolled strong biometrics with a separate vault PIN. Inactivity timeout and manual lock end the session.
Backup & recovery
Export an encrypted backup with your records and attachments. A copyable 16-character recovery key supports restoration from that backup; keep both safely available.
02 / CAMERA → SCAN → RECORD
Point. Capture.
Already attached.
A connected capture workflow inside the Android app. No scan-mode selection and no separate OCR button.
Open the camera
Frame the document. Edge detection looks for the page boundary, with optional corner adjustment if it needs help.
Let the app process it
Perspective correction and automatic image enhancements prepare the photo for bundled, offline text recognition.
Review the filled fields
The corrected color photo stays attached, preserving the card or document’s appearance. Matching empty fields are populated for you to check and edit before saving.
Add the next page
Add a card’s back side or another document page to the same entry, then save the record and its encrypted scans together.
Recognition is an aid, not a guarantee. Glare, engraving and low contrast can cause errors. Review every recognized value before saving.
03 / SEE THE APP
Life Vault, in pictures.
Eleven actual native app renders from the development build, using fictional sample records. Open any screen to explore it in detail. Still images do not show the live electrons.
01 / A welcome with lifeThe gold atom and orbiting electrons welcome you into Life Vault. This render shows first-time setup.
02 / Your vault, at a glanceDocuments, cards, certificates and other personal records in one dashboard.
03 / Important documentsOrganize document entries alongside their details and attachments.
04 / Card informationKeep editable card details together. All gallery records are fictional.
05 / One card. Both sides.Front and back remain attached to a single entry, with individual scan controls.
06 / A scan from your cameraSee the corrected scan attached immediately after processing.
07 / Less typing, more checkingRecognized warranty fields are filled automatically and remain editable.
08 / A little extra precisionAdjust the four corners when a difficult photo needs manual correction.
09 / Make it yoursAppearance, language and session preferences live inside the signed-in vault.
10 / Help within reachBuilt-in guidance explains capture, records, backup and recovery.
11 / Your card, in colorNatural colors stay visible. Contrast treatments are used only for recognition.
04 / OPEN DEVELOPMENT NOTES
Built in steps.
Documented along the way.
Current build: 0.4.1-dev · Updated 10 October 2026. Life Vault remains a development preview, with implementation evidence and known limits kept visible.
0.4.1 / NATURAL COLOR SCANS
Your card, still your card.
Saved scans now always retain the enhanced color photograph, with corrected edges and perspective. Black-and-white and contrast treatments are used only as temporary OCR inputs; recognition quality no longer decides how the saved image looks.
0.4.0 / AUTOMATIC CAPTURE
A simpler scanning workflow.
- Automatic edge detection, perspective correction and image enhancement with OpenCV.
- Bundled offline OCR runs after capture and fills matching fields immediately.
- Retained processed scans, optional corner adjustment and multiple pages per entry.
- Card front and back remain linked to the same record.
- Login electrons redraw in sync with the display’s refresh cycle; Android reduced motion and battery saver remain respected.
0.3.0 — Camera, OCR & visual identity
Introduced in-app camera capture, offline Tesseract recognition in English, German, French, Dutch, Spanish and Croatian, encrypted scan attachments and backup preservation. Added the space-and-gold presentation inspired by the approved artwork, native animated atom and settings available after login.
0.2.0 — Life Vault & session experience
Life Vault branding, certificates, built-in user guide, authenticated sessions, configurable inactivity timeout, portable preferences and improved backup verification. Device migration was tested with synthetic records; two-phone migration still needs physical-device validation.
0.1.2 — Secure setup repair
Corrected the biometric encryption setup sequence so authenticated cipher operations receive associated data at the correct stage. Kept the existing package and development signing identity for updates.
0.1.1 — Recovery you can copy
Introduced a 16-character recovery key with copy-and-paste confirmation and retained support for the earlier 64-character format.
0.1.0 — The original foundation
The project began as QBD Command Center: native Android forms, encrypted records and attachments, authentication, backup and recovery. The application package remains com.qbd.command for continuity.

The app is under active development. The gallery uses fictional sample records, and development notes distinguish implemented features from remaining work.
Strong biometrics and a separate vault PIN protect access. The current application operates locally; automatic cloud synchronization is not included.
