Secure Document Vault for Android

One Vault for Every
Important Document

Q: How do I save a file from another app into DocVault?

In your file manager, email or chat app, choose Open with or Share and pick DocVault. DocVault shows a review screen where you set the title, category and folder, then encrypts the file into your vault and deletes its temporary copy. If the vault is locked, the file waits until you unlock it.

Identity papers, medical records, certificates, property deeds, contracts and financial statements — encrypted on your phone, organized, and viewable in one tap. Open PDFs, Word, Excel and PowerPoint files right inside the vault, and zoom in on the fine print.

A vault for every part of life

DocVault organizes what matters most into secure, dedicated categories.

Identity & Birth Records

Passports, national IDs, PAN and voter cards, driving licences and birth certificates — encrypted and ready when you need proof.

Medical Records

Prescriptions, lab reports and insurance papers, organized for emergencies.

Education Certificates

Degrees, marksheets and transcripts, safe from loss, fire or damage.

Property & Home

Deeds, rental agreements and warranties, backed up and always retrievable.

Financial & Legal

Bank statements, tax documents, policies and wills, shared only with people you choose.

Signed Contracts

Agreements and signed pages, dated and kept together in one secure place.

Open any important document — right in the vault

DocVault stores the files you already have and shows them in its own viewer, so a document never has to leave the vault just to be read.

PDF

Page-by-page viewer with swipe, pinch and double-tap zoom.

DOCX

Word

Headings, lists and tables from DOCX. DOC opens in another app.

XLSX

Excel

Every sheet as a grid, with dates and numbers formatted. XLS opens in another app.

PPTX

PowerPoint

Slide-by-slide text. PPT opens in another app.

TXT · CSV

Text & CSV

Plain text notes and CSV tables, adjustable text size.

JPG · PNG

Photos & Scans

Zoom up to 500% to read small print on IDs and receipts.

Previews are built from the decrypted file in memory — no third-party viewer and no internet involved. For anything else, Open with another app hands over a temporary decrypted copy, after asking you first.

Beyond storage — a vault that works for you

DocVault fits into how you already handle files on your phone, and keeps an eye on the dates that matter.

View & Zoom New

Pinch, double-tap or use the zoom buttons on photos and PDF pages; enlarge the text of Word, Excel and PowerPoint previews.

Open with DocVault New

Save a PDF, Office file or photo straight from your file manager, email or chat app with Open with or Share → DocVault.

Open in Another App New

Need a full editor? Hand a document to Word, Excel or your PDF reader — DocVault confirms first and never lists itself.

Vaults & Folders

Start with Personal and Family vaults, then build your own folders inside each one — organize your way, on top of the built-in categories.

Scan & Upload

Photograph a document — several pages merge into one PDF — or pick a file you already have. Uploaded files are titled from their file name.

Instant Search

Find a document by its title or the details you've added — names, addresses, dates of birth, expiry dates and more.

Expiry Reminders

Add a renewal date and DocVault reminds you before a passport, licence or policy lapses — from 1 day to 12 months ahead, per document if you like.

Encrypted Backup

Back up to your Google Drive's private app storage — never your visible Drive folders — or export a password-protected backup file.

Seamless Updates New

New versions download in the background through Google Play while you keep working; restart when it suits you.

20 Languages

DocVault speaks your language from first launch, including right-to-left support for Arabic and Urdu.

Set up your vault in minutes

Scan, Upload or Share In

Capture pages with your camera, pick a file, or send one from any app with Open with → DocVault.

Encrypt & Organize

Choose a category, folder and expiry date; DocVault encrypts the file on your phone and removes the plain copy.

View Anywhere

Unlock with your fingerprint, face or PIN and open any document in the built-in viewer — online or off.

Built on a security-first foundation

On-device encryption — every document and thumbnail is encrypted with AES-256 before it's written to storage.
Only your phone holds the key — it's generated on the device and kept in the hardware keystore; there is no DocVault server holding your files.
Biometric & PIN lock — with an auto-lock timer, and a Forgot PIN flow that verifies you with your phone's own screen lock.
Private previews — documents are decrypted in memory to view them; rendered PDF pages never touch storage.
Share on your terms — sharing or opening in another app always asks first, and temporary decrypted copies are cleaned up.
Encrypted backups — restore your vault on a new device without losing a thing.
Trash, not gone — deleted documents wait 30 days before they're removed for good.

Frequently asked questions

Quick answers about DocVault. More in the User Guide and Support.

What is DocVault?

DocVault is a free Android app from Zenerly that keeps your important documents — IDs, medical records, certificates, property deeds, financial statements and contracts — in an encrypted vault on your phone. It needs no account or sign-up.

Is DocVault free?

Yes. DocVault is free on Google Play and shows no ads.

Which file types can DocVault store and open?

DocVault stores PDF, Word (DOC and DOCX), Excel (XLS and XLSX), PowerPoint (PPT and PPTX), plain text, CSV and image files such as JPG, PNG and HEIC. PDF, DOCX, XLSX, PPTX, TXT, CSV and images open in DocVault's own viewer; older DOC, XLS and PPT files open in another app installed on your phone.

Can I zoom in on documents in DocVault?

Yes. Photos and PDF pages support pinch-to-zoom, double-tap zoom and zoom buttons up to 500%, and you can drag around while zoomed. Word, Excel, PowerPoint and text previews let you enlarge the text from 75% to 250%.

How do I save a file from another app into DocVault?

In your file manager, email or chat app, choose Open with or Share and pick DocVault. DocVault shows a review screen where you set the title, category and folder, then encrypts the file into your vault and deletes its temporary copy. If the vault is locked, the file waits until you unlock it.

Are my documents encrypted, and where are they stored?

Every document is encrypted on your phone with AES-256 using a key generated on the device and kept in its hardware-backed keystore. DocVault has no server that stores documents. Optional backups go to your own Google Drive app-data folder or to a file you export, protected by a password you choose.

Does DocVault work offline?

Yes. Adding, organizing, searching and viewing documents all work without an internet connection. The internet is only used for backups you turn on and for app updates.

Does DocVault remind me before a document expires?

Yes. Add an expiry or renewal date to a passport, licence or policy and DocVault sends on-device reminders — anywhere from 1 day to 12 months ahead, plus on the day itself. You can set a different schedule for each document.

How does DocVault update?

DocVault uses Google Play's flexible in-app updates: when a new version is available, it downloads in the background while you keep working, and you restart to install it. You can also check manually in Settings → App updates.

Is DocVault available on iPhone?

Not yet. DocVault is available on Android today; the iOS version is coming soon and you can join the early access list to be notified.

What happens if I forget my DocVault PIN?

Tap Forgot PIN? on the lock screen and confirm it's you with your phone's screen lock or biometrics; you then set a new PIN and your documents stay untouched. If your phone has no screen lock or biometrics, the only way back in is Reset Vault, which erases the vault — so keep a backup.
