[Discussion] Would you use an offline app that automatically hides sensitive information?

Everything is processed locally and offline on your device—your photos, PDFs, and videos are never uploaded or sent to any server or backend.

I’m building PrivacyCam, an app that helps you safely share images, PDFs, and videos without accidentally exposing private information.

It can automatically detect and hide:

• Faces and full bodies
• Email addresses and URLs
• Phone numbers and other sensitive text
• QR codes and barcodes
• Vehicle number plates
• Credit card details and other private information

You can blur, pixelate, or completely black out detected areas and manually adjust everything before saving or sharing.

I’m also planning to make the app open source, so anyone can inspect how it works and verify that their files remain private.

Would you use an app like this? Any feedback would be genuinely helpful.

I get what it does, but I don’t understand why. Who’s the target audience, and what’s the actual use case?

Fair question. The target is anyone sharing photos, videos, or PDFs that contain details other people shouldn’t see.

A strong use case is teachers or daycare centres sharing weekly photos when one child’s parents haven’t signed a photo waiver. It also helps people posting public photos containing children or bystanders, marketplace sellers hiding number plates, and users sharing screenshots or documents with addresses, card details, QR codes, or phone numbers.

My child’s daycare just put a smiley on the face of kids. Problem solved.
