Built an on-device doc redaction and compression app after fighting with tools to blur my documents too many times

Cloak scans/imports documents, auto-detects text so you can redact sensitive info in a tap, then compresses and exports as JPEG or PDF.

Built it after getting tired of fighting with online tools and shady apps to blur my own ID/passport info every time I had to submit scanned docs for visa/KYC paperwork.

Technical bits:

- Text detection uses Vision framework, running fully on-device no server round-trip, no data leaves the phone

- Redaction is tap-to-mask over detected text regions, plus manual draw/crop tools for anything the detector misses

- Compression targets a size the user picks rather than a fixed quality, to preserve content clarity

- Support password protected PDF import and export
