About
Fuseo makes photos of Japanese identity documents safe to submit.
WHAT IT DOES
- Capture a document with the camera or import it from Photos
- Fuseo identifies the document type (My Number Card, driver's license, health insurance card, residence card, certificate of residence) and suggests the fields that should be masked — each with the legal or practical basis shown
- Redactions are burned into the image pixels: nothing can be peeled off or restored afterwards
- Deskews the photo, exports clean PDF/JPEG/PNG copies (color, grayscale, or black & white), ready to share
- Opens PDFs too, including password-protected ones. Each page is rasterized and redacted as an image, so nothing underneath can be recovered (searchable text is re-added by OCR, excluding masked areas)
- Open files straight from Mail or Files with "Copy to Fuseo"
- Your work is saved automatically. Resume any document from "Documents in progress" (stored on this device only, excluded from iCloud backup)
THREE GUARANTEES
1. 100% on-device — no uploads, no account, no tracking. The app contains no networking code at all
2. Irreversible redaction — avoids the classic "highlighter that shows through" and "annotation layer" accidents
3. You always confirm before saving — automatic detection is a suggestion, never the final word
NOTES
- Automatic detection is not perfect. Always check for missed spots before submitting
- Some documents must be kept unmasked by law (e.g., certain tax forms) — check with the recipient
- The built-in presets target Japanese identity documents
- PDFs are processed as images; text in the exported PDF is not selectable unless you turn on searchable PDF (OCR)
Fuseo protects personal data, so its processing engine is open source (MIT).
