About this app

Your landlord wants a bank statement. The buyer wants your ID. Inkblock blacks
out the account numbers, addresses and card numbers in any PDF, photo or
screenshot — permanently, so the hidden text cannot be copied back out.

Scan or import any document — a bank statement, a contract, an ID, an invoice —
and Inkblock automatically detects phone numbers, email addresses, physical
addresses, card and account numbers, SSNs and other government IDs, dates of
birth and more. Review the suggestions, tap to accept, and export a copy with the
sensitive parts permanently removed.

PERMANENT, AND SHARP
Inkblock doesn't lay a shape over your text. It re-renders the page and burns
the bar into the pixels, so the hidden characters are gone from the file itself
— nothing to select, copy or recover from what you send. Exported as lossless
PNG at up to 2480px on the long side, with the document's title and author
fields dropped along the way.

100% ON-DEVICE
Text recognition, detection and redaction all run locally. No cloud processing,
no ads, no analytics SDK. Your documents never leave your phone.

SMART DETECTION — 25 detectors, free
Found for you automatically, with no tapping and no upgrade:
• Phone numbers, emails, addresses
• Card numbers (Luhn-validated), bank/account numbers, IBANs
• SSN, Aadhaar, PAN, passport, driving licence
• Names, dates of birth, IP addresses
• Your own custom patterns (Pro)

FREE
• Scan & import PDFs, photos and screenshots
• Automatic detection

INKBLOCK PRO
• One-tap automatic redaction
• Batch-process several documents at once
• Custom detection rules
• Secure vault — AES-256 encrypted, unlocked with biometrics
• Unlimited exports

Perfect for sharing statements with a landlord, sending contracts, redacting an
ID for a marketplace sale, or anything with personal data you'd rather not
expose.

Sign-in is optional and unlocks nothing. If you never sign in, we never learn
your name or email — and your documents are never uploaded either way.

Blackout, not cover-up. And it never leaves your phone.

What’s new

• Aadhaar Virtual IDs (VID) are now detected and fully redacted
• Fixed: the last 4 digits of some 16-digit numbers could stay visible after redaction
• An Aadhaar number printed just below a date of birth is now found
• Year headings in statements are no longer mistaken for Aadhaar numbers
