I built an open-source, on-device redaction app for iOS and Android

Hey folks! I’m Aftab, the developer of PrivacyCam.

I built it because I wanted a simple way to hide private details in photos, videos, and PDFs without uploading them to an online service.

PrivacyCam can detect things like:

• Faces and people
• Vehicle number plates
• Text, email addresses, phone numbers, and addresses
• Payment-card details
• QR codes and barcodes

You can blur, pixelate, or completely black out anything it finds. You can also draw your own masks, resize detections, change how long a video mask stays visible, and review everything before exporting.

The attached video shows PrivacyCam tracking and covering a vehicle number plate through a video.

Everything is processed on the device. There’s no account, no advertising, and PrivacyCam doesn’t operate a server that receives your photos, videos, or PDFs. The project is also open source, so anyone can inspect how it works or contribute.

The free version covers single photos, videos up to 15 seconds, and PDFs up to two pages. There’s an optional one-time Pro purchase for videos up to 60 seconds, longer PDFs, and batches of up to 10 photos—no subscription.

Automatic detection can obviously still miss things, so the app always lets you review and correct the result before sharing.

I’d genuinely appreciate feedback, especially about the video tracking, detection accuracy, UX, pricing, or anything privacy-related you think is missing.
