## What is Privacy Factory?

Before you upload, run it through Privacy Factory.

Before handing an ID copy to a bank, landlord or recruiter — stamp it with a "for X use only" anti-fraud watermark. Before sharing a screenshot — actually black out the sensitive parts. Before uploading a photo — strip the GPS and capture info. Three jobs, one app, all done on your iPhone.

ID WATERMARK
- 12 templates for common scenarios: account opening, renting, job applications, SIM cards, tax filing and more
- Full-bleed diagonal watermark overlapping the ID content, making copies hard to misuse
- Adjustable opacity, angle and color; optional date stamp

REAL REDACTION
- You may not know: a built-in marker "black-out" can be undone by simply raising brightness
- Privacy Factory redaction overwrites pixels and re-encodes flat — it cannot be recovered by adjusting brightness or color
- Brush, rectangle and mosaic tools; Pro adds automatic face and ID-number detection (Vision)

METADATA CLEANING
- See what hides in your photos: GPS, capture time, camera serial, author fields
- Export a clean copy in one tap, with a cleaning report
- Pro can keep the capture date and strip everything else

PDF TOO
- Per-page watermark plus full-page flattening, document properties cleaned as well (first PDF free)

PRIVACY IS THE PRODUCT
- 100% on-device processing; this app uploads nothing
- No accounts, no ads, no tracking — App Store privacy label: "Data Not Collected"
- Your originals are never modified — the unwatermarked photo is always still there

Free version: full features for single photos, with no app watermark on output.
Privacy Factory Pro is a one-time NT$90 purchase: batch processing, auto-detection, unlimited templates and unlimited PDFs. No subscription — yours forever.
