Screenshots get thrown out of court.
ProofSnap doesn't.

ProofSnap is a Chrome and Edge extension that captures web pages as legal evidence with blockchain timestamping, ensuring the authenticity and integrity of digital evidence.

ProofSnap uses OpenTimestamps to anchor a SHA-256 hash of your evidence to the Bitcoin blockchain, creating a cryptographic proof that the package existed no later than the anchor time. The proof is independently verifiable and cannot be backdated. It is included on every plan except Essential.

ProofSnap includes a 7-day free trial with all plans. Choose from flexible monthly or annual subscriptions: Essential ($8.99/month or $80/year), Professional ($16.99/month or $160/year), or Enterprise ($28.99/month or $280/year). Annual plans save up to 26%. Every plan and SnapPack is broken down in ProofSnap plans and prices explained.

Yes. In the ProofSnap Dashboard at app.getproofsnap.com you paste one or more URLs and our servers load the pages and return the same sealed evidence package. It works for public pages; for a page behind a login or paywall, use the extension. A new dashboard account starts with 50 free test captures, and the dashboard and the API have their own plans, separate from the extension.

ProofSnap generates forensically sound evidence with cryptographic proofs aligned with eIDAS 2 standards for qualified timestamps and digital signatures. Admissibility depends on jurisdiction and specific legal requirements. Consult with legal professionals for specific cases.

Regular screenshots can be challenged in court because they lack proof of when they were taken and whether they've been altered. In Nigeria, section 84 of the Evidence Act 2011 (expanded by the Evidence (Amendment) Act 2023) lets a computer-generated document in, but only when its integrity is established: the party relying on the screenshot must satisfy the statutory conditions, usually with a certificate of compliance, and any sign the record was edited or manipulated can render it inadmissible. A plain screenshot is weak on exactly those points. Other jurisdictions apply similar authentication rules, such as the authentication rules of the US Federal Rules of Evidence.

ProofSnap addresses these challenges by creating a forensic evidence package that includes: a SHA-256 cryptographic hash that shows whether the content has been modified, a digital signature over the manifest, a blockchain timestamp proving the capture existed no later than the anchor time (not on Essential), and full metadata (URL, browser info, HTTP headers). This makes your capture significantly more defensible under the integrity test than a plain image file. The whole workflow is shown screen by screen in how to capture a web page as evidence.

ProofSnap uses three layers of cryptographic protection:

1. SHA-256 Hashing: Every file in the evidence package is hashed. Changing even a single pixel or character produces a completely different hash, making any tampering immediately detectable.
2. Digital Signature: The manifest (listing all files and their hashes) is digitally signed with a private key. The corresponding public key is included for anyone to verify authenticity.
3. Blockchain Timestamp: The manifest hash is anchored to the Bitcoin blockchain via OpenTimestamps, creating an immutable record of when the evidence was captured. This timestamp cannot be forged or backdated.

Together, these mechanisms create a chain of integrity that proves the evidence is authentic, unaltered, and was captured at a specific point in time. Anyone can check this; see how to verify a ProofSnap evidence package.

Regulation (EU) 2024/1183 is fully rolling out by the end of 2026, establishing stricter standards for electronic identification, digital signatures, and qualified electronic timestamps across all EU member states.

Under Article 41(2), qualified electronic timestamps enjoy a legal presumption of accuracy for the date and time they indicate, and the integrity of the data to which the timestamp is linked. The presumption is rebuttable, and admissibility itself is still decided under each member state's own procedure.

In Nigeria the position is different. Nigeria is not an EU member state, so the Article 41(2) presumption does not arise before a Nigerian court. The qualified timestamp is independent technical corroboration of when the capture existed, which the court weighs freely, while admissibility itself is decided under the Evidence Act.

ProofSnap's cryptographic proofs align with eIDAS 2 requirements: SHA-256 hashing for data integrity, RSA-4096 digital signatures for authenticity, and blockchain timestamps via OpenTimestamps for independent time verification. This makes ProofSnap evidence packages suitable for legal proceedings in Nigeria and across the EU.

Yes. The EFCC accepts petitions in writing and through its Eagle Eye reporting app, launched by the Commission in July 2021 for reporting economic and financial crimes, and supporting documents can be attached. Capture the scammer's WhatsApp chat, Instagram profile, or payment request with ProofSnap, then attach the signed evidence PDF to your petition or hand it to the police. A petition backed by a complete, tamper-evident record is far easier for an investigator to act on than a loose set of screenshots.

ProofSnap does not report the case for you. It preserves the record in a tamper-evident package with a SHA-256 hash and a Bitcoin blockchain timestamp, so the scammer cannot later claim your screenshot was faked or taken out of context.

Under section 84(2) of the Evidence Act 2011, a computer-generated document is admissible only if you show the computer was working properly and the record was produced in the ordinary course of use. Section 84(4) lets you establish this with a signed statement, commonly called a certificate of compliance. That certificate is a legal document you or your lawyer sign, so ProofSnap does not issue it for you.

What ProofSnap gives you is the technical foundation the certificate relies on: a SHA-256 hash, an RSA-4096 digital signature, a Bitcoin blockchain timestamp, and a forensic log showing how, when, and from where the page was captured. That makes the integrity of your record far easier to attest to, and much harder for the other side to dispute.

Forensic mode is an optional deeper capture included in the Professional, Enterprise and Company plans (not in Essential or the SnapPacks).

Adds a complete archive of the page's network layer: every HTTP request and response (network.har), a WARC copy of the page, all loaded resources, and the TLS session and certificate details. To capture that it attaches the debugger (the browser shows a “being debugged” banner).

Every one of those files is hashed into the RSA-4096 signed manifest, so the OpenTimestamps blockchain anchor and the eIDAS qualified timestamp cover the network archive exactly as they cover the screenshot. Step by step: how to use forensic mode.
