Dokum: Watermark & Redact ID

Your documents shouldn't be a liability. Dokum lets you watermark, redact, and safely share your KTP, SIM, or passport — fully on-device, no servers, no subscriptions.

Dokum is a privacy-first document utility for iPhone. Built for anyone who's ever felt uneasy sending a photo of their KTP, SIM, or passport to a rental shop, a bank, or a stranger on the internet.

No backend. No subscriptions. Everything happens on your device and syncs privately through your own iCloud.

• Biometric Vault: Your documents live behind FaceID or a passcode. The app also blurs itself in the app switcher so no one catches a glimpse over your shoulder.
• Permanent Redaction: A finger-paint tool that physically overwrites pixels with black blocks. Not a layer. Not reversible. Gone.
• Smart Watermarking: Add tiled or centered text overlays with custom opacity and rotation. "FOR RENTAL ONLY." "FOR BANK USE ONLY." Whatever you need the recipient to see.
• Smart Export: Share the current page as an image, stitch all pages into a single long image, or generate a multi-page PDF — all from one export screen.
• Metadata Scrubbing: Every export strips EXIF, GPS, and device metadata. The file you send out is clean.
• Fully Offline: No internet required. Scan, redact, watermark, and export in airplane mode. iCloud syncs your vault quietly in the background when you're back online.

Dokum doesn't solve a big problem. It solves the small one you've been ignoring every time you hit send.
