Everything you need to go paperless
Sharp scans in seconds
Automatic edge detection, perspective correction and filters for colour, greyscale or black and white. Adjust the corners by hand whenever you want.
Text recognition on the device
Copy the text of any page, save searchable PDFs and find documents by the words inside them. Recognition never leaves your phone.
Redaction you can trust
Hide account numbers, IDs and signatures permanently. The hidden content is removed from the exported file, not just covered.
Complete PDF tools
Merge, split, compress, annotate, sign, add watermarks and protect PDFs with a password. Every edit creates a new copy.
A library that stays tidy
Folders, tags, favourites and filters keep contracts, receipts and forms easy to find, with document names suggested for you.
Vault and backup
Keep sensitive files in an encrypted vault behind your screen lock, and create your own backup file to move to a new phone.
A look inside
Private by design
Cadrivault has no account, no ads, no analytics and no servers. The app does not even request internet access: your documents, recognised text and search index are stored only on your device until you choose to export or share them.
Free and Pro
Scanning, cropping, filters, the library, single-page text recognition and exports without watermarks are free. Cadrivault Pro adds batch recognition, searchable PDFs, search inside documents, permanent redaction, password protection, the vault and advanced PDF tools — monthly, annual or as a one-time lifetime purchase on Google Play.
Made for real paperwork
Accounting and law offices, freelancers and families use Cadrivault for contracts, receipts, invoices, IDs and forms. Cadrivault is a tool for organizing documents; it does not give legal, tax or financial advice.
