About this app

Don't send your ID or records as they are. CopySeal covers the back digits of the ID number, stamps who the copy is for plus a copy number, and gives you a single A4 page.

HOW IT WORKS
- Pick a type, take a photo or open a PDF, check the masks, add a watermark, send
- Korean resident card, driver's license, passport, residence card, bankbook copy and other documents
- Open a records PDF as it is and handle up to 10 pages at once

NO DIGIT LEFT BEHIND
- Text recognition covers the back digits of ID and registration numbers automatically
- Masks are burned into the picture, so they cannot be brought back from the PDF
- Tap a box to turn it on or off, or zoom in and cover an area yourself
- If nothing is found you are told, and you must confirm before moving on
- Optionally keep the gender digit visible

TRACE EVERY COPY
- A recipient, purpose and date watermark goes over the picture, with one more line at the bottom of the A4 page
- Each copy gets a copy number; if a copy leaks, look the number up in My copies to see where you sent it

ON YOUR DEVICE
- Photos and PDFs are processed on the device; the unmasked original is deleted once the copy is made
- No login or sign-up; your copies stay on this device
- Screens that show your ID block screenshots and recent-apps previews (can be turned off)
- 12 languages, switch inside the app

Note: the first scan may need an internet connection while Google's document scanner module downloads. Banner and interstitial ads are shown, and a one-time purchase removes ads. Always check the masks with your own eyes before you send.
