That black markup tool?
It doesn't hide your data.
Drawing black lines in basic photo apps leaves underlying pixels and GPS metadata completely recoverable. CensorFyn uses on-device AI to permanently overwrite raw pixel bytes with irreversible mathematical destruction.
Semi-transparent vector pens easily revealed by adjusting image brightness, plus intact GPS coordinates.
Permanent Gaussian/Mosaic raster overwrite, automatic GPS scrubbing, and optional SHA-256 audit trails.
Irreversible Raster Overwrite
Raw pixel data permanently destroyed
Why Photos Need Mathematical Destruction
Most mobile markup tools simply place semi-transparent overlay boxes that can easily be stripped or brightened. CensorFyn was built for true, permanent privacy.
Gallery Markers Leak Hidden Data
Drawing a black marker over a document or photo doesn't erase it. Anyone can adjust brightness, contrast, or exposure to read the sensitive text underneath. CensorFyn permanently overwrites the raw pixel bytes.
True Destructive Raster Overwrite
Unlike basic markup tools that add removable layers, CensorFyn applies true mathematical destruction: Gaussian blur, mosaic pixelation, or solid redaction baked permanently into the image bytes.
Automatic GPS & Metadata Purge
Every smartphone photo embeds camera serials, timestamps, and exact home GPS coordinates. CensorFyn automatically scrubs all EXIF tracking data before you share.
100% On-Device AI & Legal Audit
BlazeFace and Vision OCR run entirely offline on your phone's processor. Optional Audit Mode generates tamper-evident SHA-256 cryptographic manifests for court and compliance.
A Smooth 5-Step Sanitization Flow
From photo import to sanitized, metadata-clean export with zero hassle.
1. Instant Local Import
Select photos or share directly from Gallery. Processing runs 100% offline with zero server uploads.
2. Dual AI Detection
Combines BlazeFace & Vision OCR to detect faces, passports, credit cards, phone numbers, and QR codes.
3. Precision Masking
Switch between Blur, Mosaic Pixelate, and Solid Color masks, or draw manual freehand boxes.
4. Metadata Sanitization
Strip EXIF and GPS tracking data, with optional legal SHA-256 audit manifest export.
5. Safe to Share
Irreversibly destructs raw image pixels so sensitive data can never be unmasked or recovered.
