## What is PDF Vault?

PDF Vault handles the everyday PDF jobs: scan, compress, merge, convert, sign. Then it does what other PDF apps leave out: it locks the result behind a PIN, in an encrypted vault on your own device.

Every page is processed on your phone or tablet. Your documents are not uploaded to a server for conversion, because there is no server.

SCAN
• Scan documents to PDF: edges are found for you, and you can keep adding pages
• Scan ID card: front and back on a single page
• OCR turns scans into a searchable PDF, using your device's own text recognition (Pro)

PDF TOOLS
• Compress PDF to make a file smaller; with Pro, compress to a size you choose, for upload forms with a limit
• Merge & organize: combine files, then reorder, rotate, delete or split pages
• Images to PDF, and PDF to images
• HEIC convert: turn HEIC photos into JPG or PDF
• Word/PPT to PDF: converts .docx and .pptx files
• Sign: draw your signature once, then place it on any PDF
• Print PDF
• Your most-used tools come first on the home screen, and you can rearrange the tiles

THE VAULT
• Encrypted on your device and opened with your PIN, or with your fingerprint or face
• A recovery code is the only way back if you forget the PIN. We do not have your key
• Opens PDF, Word, Excel, PowerPoint, text, CSV, pictures, video and audio inside the app
• The lock guards the vault only. The tools open straight away

BROWSER, SYNC AND BACKUP
• A built-in browser downloads PDFs, pictures and files straight into the app
• Sync the vault between your own devices over your local network
• Encrypted backup to a folder you choose

PRIVACY, IN PLAIN WORDS
• No account, no sign-up
• Files are processed on the device and never uploaded
• The free version shows ads from Google AdMob. They are non-personalised and never appear inside the vault, the viewers or the browser

FREE AND PRO
Free: scanning, every tool not marked Pro, the browser and a vault that holds up to 20 files. Ads support it.
Pro: removes ads, unlocks OCR and compress to a size, and lifts the limit on the vault (within your device's storage). Choose a yearly subscription, with a 3-day free trial for first-time subscribers, or a one-time lifetime purchase.

GOOD TO KNOW
• Word and PowerPoint conversion handles .docx and .pptx, not the older .doc and .ppt. The layout of the PDF can differ from the original
• A signature is an image of your handwriting, not a certified digital signature
• The vault lives only on your devices. Keep a backup
