## What is Evidiq?

Evidiq seals every photo and video at capture in the open C2PA format. The result: proof that holds up, even with someone who has no reason to believe you.

WHEN IT HELPS
• A jobsite before and after the work.
• The condition of a property at check-in or check-out.
• Damage you need to report.
• A scene you will have to explain, six months from now, in terms of when and where it was photographed.

WHAT THE APP DOES
• You capture inside the app.
• Every photo or video is sealed in the C2PA format, with its timestamp and, if you allow it, your position.
• Sealing records a signature of the file: any later edit becomes detectable.
• You get a verification link to share. Whoever receives it opens a public page that states what was verified, check by check. They can redo the computation themselves.
• No account is needed to verify.

A PROOF FILE TO KEEP
From the verification page, your recipient downloads the proof file: a PDF that gathers the verifiable items and explains how to check them without going through us. It stays verifiable even if you withdraw the link.

WHAT IT PROVES, AND WHAT IT DOES NOT
Evidiq proves the origin of a file and its integrity since capture, not the honesty of the photographed scene.

The verification page shows a plain-language verdict and the capture signal level, never an isolated number. Every check listed below comes with its own reason. The scoring rubric is public.

LIVE CAPTURE ONLY
The app does not access your gallery. You cannot import an existing image, and that is deliberate: a proof is only worth something if it is born in the device that seals it.

INDEPENDENT VERIFICATION
• Each proof first gets an independent timestamp (an RFC 3161 authority), then, in batches, an entry in the Bitcoin blockchain that confirms it.
• Your images and your personal data never go on the blockchain: it only receives an anonymous digest.
• Whoever receives a proof can redo the computation from the file and check the timestamp directly in their browser, without taking our word for it.
• The C2PA format we use is an open standard, readable by tools other than ours.

PRICING
• Three proofs free every month.
• Beyond that, packs with no subscription: 1, 5 or 12 proofs.
• Bought once, valid with no time limit.

## Version history (last 2 releases)

### 1.3.7 — 2026-10-06

Your proofs match what you actually captured.
• If a photo or video is changed on your phone between the shot and the seal, it cannot be sealed: the app tells you and offers to retake it.
• When someone sends you a link to take a photo for them, retaking a capture now starts from scratch.

### 1.3.0 — 2026-09-25

No release notes.
