## What is InkStamp?

InkStamp is a private photo watermarking app for creators, online sellers, photographers, students, and anyone who wants their photos to travel with a signature — not with tracking.

Add text, signatures, logos, copyright notes, retro stamp effects, or invisible watermarks without sending your images to a server. Every edit is processed on your iPhone or iPad.

KEY FEATURES

• Photo watermark editor
Layer text, signatures, logos, dates, copyright labels, and retro stamp effects on a single photo. Drag to position, rotate up to 360°, tune opacity, and preview in real time.

• Batch watermark export
Import a full shoot, pick one watermark style, preview every image, then export the whole batch in one flow. Perfect for shops, portfolios, class photos, and client previews.

• Invisible watermark
Embed a mark that is imperceptible in normal viewing but can be verified later with the in-app detector. Useful for proving ownership of a leaked shot.

• Templates for repeat use
Save your go-to stamp as a template so every export stays on-brand without re-adjusting rotation, opacity, or position.

• Private by design
No account. No ads. No analytics. Photos are processed on-device and are not uploaded by InkStamp.

• Retro look that sets your photos apart
Cream paper, coral ink, mint accents, classic stamp motifs. Your watermark signals craftsmanship, not stock filters.

WHY INKSTAMP IS DIFFERENT

1. The invisible-watermark detector is built in, not sold as a separate app. You can verify your mark later, even on a screenshot a friend took.
2. Batch mode treats every batch as one trip: you preview, adjust, and export all images together, so every photo carries the same signature.
3. Everything happens on-device. InkStamp never uploads the photos you stamp.

WHO IT IS FOR

InkStamp is useful for:
- Photographers watermarking client previews before delivery
- Online sellers protecting product photos on marketplaces
- Designers and illustrators adding signatures to portfolio work
- Students and teachers marking submitted assignments
- Creators stamping the shots they share on social platforms
