Tap the + button on the Home screen, then choose Scan to use your camera or Upload to import an existing file. Assign it a category and DocVault encrypts and saves it automatically.

DocVault stores PDF, Word (DOC, DOCX), Excel (XLS, XLSX), PowerPoint (PPT, PPTX), plain text, CSV and images (JPG, PNG, HEIC and more). Camera scans of several pages are merged into one PDF automatically. See Supported File Types for which formats preview in-app.

Yes. DOCX, XLSX and PPTX files open in DocVault's own viewer — Word with its headings, lists and tables, Excel with every sheet, and PowerPoint slide by slide. PDFs, text, CSV and images open in-app too. Older DOC, XLS and PPT files are stored safely and open in another app via Open with another app.

In the viewer, pinch with two fingers, double-tap where you want to zoom, or use the − / + buttons at the top — photos and PDF pages zoom up to 500%, and you can drag around while zoomed. For Word, Excel, PowerPoint and text files the buttons change the text size from 75% to 250%. Tap the percentage to reset.

Tap Open with or Share on the file and choose DocVault. Unlock if asked, check the title and category on the review screen, and tap Save to Vault. DocVault encrypts the file and deletes its temporary copy.

Password-protected PDFs and older Office formats can't be shown in DocVault's viewer. Tap Open with another app to view it in Word, Excel or your PDF reader — DocVault asks for confirmation first, since this hands over a decrypted copy.

No. Documents are encrypted on your device with a key generated on your device and stored in its secure hardware keystore — it never leaves your phone, and there's no server that ever sees your files. See our Privacy Policy for details.

Tap Forgot PIN? on the lock screen and confirm it's you with your phone's own screen lock or biometrics — you'll set a new PIN and your documents stay untouched. If your phone has no screen lock or biometrics, the only way back in is Settings → Reset Vault, which permanently erases everything on the device. This is why keeping a backup (local export or cloud sync) is strongly recommended.

Never. Biometric checks happen entirely inside your device's secure hardware. DocVault only receives a pass/fail result.

There's no account to sign into — instead, install DocVault on the new device and tap the cloud icon at the top of your vault to open the Backup screen. If you enabled Google Drive/iCloud backup, connect the same account and tap Restore; otherwise, import the .dvbackup file you exported from the old device and enter its password. Everything is decrypted locally on the new device.

Yes — DocVault works fully offline day-to-day; scanning, organizing, and searching your vault never require a connection. Internet is only used when you actively connect Google Drive/iCloud or tap "Back up now." Nothing uploads automatically unless you've turned on the "Back up automatically" toggle in Settings.

No. The backup is stored in each service's hidden, app-private storage area (Drive's "App Data" folder, iCloud's app container) — it won't show up alongside your regular files.

Open the document and tap Share — DocVault decrypts a copy and hands it to your phone's normal share sheet, so you can send it via email, WhatsApp, Drive, or any app you choose. This is a one-time export you control; there's no hosted link involved.

DocVault uses Google Play's in-app updates. When a new version is out, Google Play asks once, downloads it in the background while you keep working, and DocVault then offers Restart to update. You can also go to Settings → App updates → Check for updates.

In-app updates are delivered by Google Play, so they only work for DocVault installed from the Play Store. Copies installed another way need to be updated from the Play Store listing.

DocVault has no server account, so this is instant and entirely in your hands: go to Settings → Reset Vault to permanently erase everything on this device. If you'd also like us to delete any data you've sent us directly (e.g. an early-access signup), use our Account & Data Deletion page.
