21 PDF tools that run 100% on your Android. Sign, redact, OCR, fill forms, compare, encrypt. Nothing leaves your device.

Privio is the offline PDF toolkit for lawyers, accountants, real estate professionals, and anyone whose documents shouldn't be on a stranger's server. Every operation runs locally on your phone — your PDFs never leave this device.

THE 21 TOOLS

Document intake
• Scan to PDF — on-device scanner with edge detection and multi-page capture
• OCR PDF — on-device text recognition adds a searchable text layer you can tap to select and copy
• Image to PDF — photos, receipts, screenshots into one PDF
• Merge PDFs — combine at the document level or hand-pick pages
• Compress PDF — shrink for email without visible quality loss
• Split PDF — extract page ranges, every Nth page, or N equal parts

Editing
• Rotate pages — fix sideways scans
• Delete pages — drop what you don't need
• Sign PDF — finger or stylus signature with SHA-256 audit footer
• Fill form — IRS, USCIS, court motion forms with flatten-on-save
• Page numbers — four formats, five positions, custom start
• Bates numbering — legal discovery standard
• Password protect — AES-256 encrypt or unlock

Review
• Watermark — CONFIDENTIAL, DRAFT, custom text in three layouts
• Extract text — pull clean text out of any born-digital PDF
• Compare PDFs — redline two versions, added and removed text
• Bookmarks / TOC — jump to any chapter in long briefs and depositions
• Find sensitive data — auto-detect SSN, EIN, credit cards (Luhn validated), IBANs, emails, phone numbers
• Redact — search words, render-and-flatten removes them from the data stream

Batch + receipts
• Batch operations — compress, watermark, or rotate a stack of PDFs in one pass
• Receipt scanner — date / vendor / total / tax → QuickBooks-friendly CSV

ANDROID INTEGRATION
Home Screen widget. Share Sheet routing. Storage Access Framework integration. Recent files follow the language you pick in Settings.

PRIVACY
Other PDF apps upload your file to "process" it in the cloud. Privio keeps your work — and the privileges that protect it — on your phone.

Privio uses on-device frameworks only: Google ML Kit for scan and OCR, the open-source pdfium for assembly. No cloud calls. No third-party analytics, no crash-reporting SDK, no ad SDK, no tracking, no account. The Play Data Safety section shows "Data Not Collected."
