## What is OPCam?

OPCam turns your iPhone into a tamper-evidence camera for fieldwork, inspections, and any photo that has to be trusted.

• Time, GPS coordinates and address are burned into the original photo — they can't be edited out
• Every photo gets a SHA-256 fingerprint of the exact image file you share — so anyone holding the photo can recompute it and check it themselves
• Optional on-chain anchor: the fingerprint is recorded on Optimism, so anyone can independently verify the photo existed at that time
• Record library with timeline, place and live map views
• Choose exactly which fields go into the watermark
• 24 languages

Your photos stay yours — saved to your photo library. The on-chain anchor stores only a hash fingerprint, never the image.

## Version history (last 5 releases)

### 1.4 — 2026-08-20

• Share a proof. Send the photo together with a JSON file holding its fingerprint and every watermark field, so whoever receives it can check it themselves.
• Back up and restore your whole record log — every record and every photograph in one archive.
• Manage storage: delete individual records, see how much space the log uses, and reclaim photos nothing references any more.
• A short guide on first launch, including a plain statement of what OPCam can and cannot prove.
• On-chain credits are now held on the server, so they survive reinstalling the app. Purchases that fail or need approval now say so instead of doing nothing.
• The watermark no longer runs off the edge of the photo on long addresses, and is laid out correctly in Arabic, Hebrew and Persian.
• Fixed a bug that could stop OPCam from reading back its own record log.

### 1.3 — 2026-08-18

• On-chain proofs can now be verified by anyone. A photo's SHA-256 fingerprint now covers the exact image file you share, so a recipient can recompute it and check it against the chain.
• The watermark now carries the record number. The full fingerprint is on the receipt, and you can copy it.
• Records made before this update are marked as legacy — their older fingerprints cannot be recomputed from the photo.
• Camera, location and photo-library permissions are now explained instead of failing quietly. OPCam will not create a record without the camera.
• Pending on-chain anchors are re-checked when you reopen the app.
• Text now follows your system text size, and every control is labelled for VoiceOver.
• Fixes: address formatting outside Chinese, a duplicated time zone, and a case where a damaged log could lose your settings.

### 1.2 — 2026-07-15

• New on-chain credits store with a simple purchase guide, plus reminders when your credits run low or run out.
• You can now open a photo's on-chain proof on the block explorer, directly from the receipt.

### 1.1 — 2026-07-08

• Fixed a rare crash when taking a photo
• Faster, smoother capture with no white-screen delay
• Tap any record to view the full watermarked photo — pinch to zoom
• Design and stability improvements

### 1.0 — 2026-07-06
