Screenshots get thrown out of Singapore courts.
ProofSnap doesn't.

ProofSnap is a Chrome 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 of when the capture was made. This timestamp is independently verifiable and cannot be backdated or tampered with, providing irrefutable proof that your evidence existed at a specific point in time.

ProofSnap includes a 7-day free trial with all plans. The trial requires a credit card, and you are not charged if you cancel before it ends. Choose from flexible monthly or annual subscriptions: Essential, $8.99 per month (approx. S$11.50) or $80 per year (approx. S$102); Professional, $16.99 per month (approx. S$21.80) or $160 per year (approx. S$205); Enterprise, $28.99 per month (approx. S$37.20) or $280 per year (approx. S$359). Annual plans save 20%.

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 a Singapore lawyer about your own case.

Regular screenshots can be challenged in court because they carry no proof of when they were taken or whether they have been altered. In Singapore two rules decide what happens next. Procedurally, authenticity is deemed admitted until the other side serves a notice of non-admission, and once it does, the party relying on the document has to prove it was made as it purports to have been. Substantively, section 116A(1) of the Evidence Act 1893 lets you get there through the process rather than through a witness's recollection: where a device or process ordinarily produces or accurately communicates an electronic record, the court presumes it did so on the occasion in question, unless evidence sufficient to raise doubt is adduced.

ProofSnap addresses this by creating a forensic evidence package containing a SHA-256 hash proving the content has not been modified, an RSA-4096 digital signature for authenticity, an eIDAS qualified timestamp issued by Disig a.s., a Qualified Trust Service Provider on the EU Trusted List, a Bitcoin blockchain anchor, and full metadata including the URL and the capture time in UTC. The presumption goes to the time and the integrity of the data rather than to admissibility generally or to the truth of what the page said, so a court or an adjudicator still weighs the evidence. What it removes is the argument about when the capture was made and whether it changed afterwards.

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 that it was captured at a specific point in time.

Regulation (EU) 2024/1183, known as eIDAS 2, will be fully rolled 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), a qualified electronic time stamp shall enjoy the presumption of the accuracy of the date and the time it indicates and the integrity of the data to which the date and time are bound. That presumption operates in the European Union. It does not reach Singapore, which is not an EU member state and has not adopted eIDAS, so before a Singapore court the operative provision is section 116A of the Evidence Act 1893 and the qualified timestamp is corroboration rather than a presumption.

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 Singapore and, where a matter crosses into Europe, across the EU.

Less than people hope, and enough to matter. Section 116A(1) presumes that where a device or process is one that, if properly used, ordinarily produces or accurately communicates an electronic record, it did so on the occasion in question, unless evidence sufficient to raise doubt about the presumption is adduced. In GIL v Public Prosecutor [2025] SGCA 21 the Court of Appeal held that the person giving evidence about the system needs only "a broad understanding of the process".

What it does not do is equally important. The same judgment holds that the presumption "only presumes that the electronic record in question was produced or accurately communicated by that process", that there is "no presumption as to the truth of the content of the record", and that it "does not dispense with or shift the burden to prove the reliability of the data". So the presumption gets your capture admitted; the hashes, the signed manifest and the chain of custody are what persuade the court it is reliable. Section 116A(6) also lets a Certifying Authority certify a record-keeping system as an approved process, which is optional but useful for organisations relying on their own systems.

One month, and then a second clock. A wrongful dismissal claim starts with mediation at the Tripartite Alliance for Dispute Management, and TADM states that it must be filed within one month of your last date of employment, failing which the claim is time-barred. Mediation is compulsory before the claim can go further. If it does not resolve the matter, the mediator issues a Claim Referral Certificate and the claim must be filed at the Employment Claims Tribunals within four weeks of that certificate, where a claim is capped at S$20,000, or S$30,000 for a union member.

Employer systems are usually locked on the day of dismissal, so the roster, the internal message thread, the HR portal entry and the manager's post are often gone before the mediation date. Capture them the same day, and exhibit the package rather than a bare screenshot.

Capture first, report second. The Commission has been taking reports since 29 June 2026 and covers online harassment, doxxing, online stalking, intimate image abuse and image-based child abuse. It can direct a platform to make the material inaccessible in Singapore, restrict or ban an account, and require a right of reply, and prescribed platforms must act within 24 hours for intimate image abuse or image-based child abuse and 48 hours for the other harms. Once that happens the material is gone, and with it any chance of documenting what was posted.

Capture each item as its own package: the post or image, the account profile behind it, the thread or group it appeared in, and any message you received. Keep them separate, because the statutory tort for intimate image abuse and image-based child abuse awards at least S$5,000 for each image or recording, so the count matters and a single composite screenshot of a gallery proves far less than one sealed capture per item. The same file then serves a police report, a Protection from Harassment Act application and a civil claim, without you having to go back to a page that no longer exists.

That is the objection every screenshot invites, and with a plain image there is no answer to it beyond your own word. Once a notice of non-admission is served, the party relying on the document has to prove it was made as it purports to have been, and a picture supplies nothing to prove it with.

A ProofSnap package answers the objection from the file. Every file carries a SHA-256 hash, the manifest listing those hashes is signed with an RSA-4096 key, the public key travels with the package, and the verification scripts recompute all of it in front of whoever is asking. Change one pixel and the hash no longer matches. That also puts you inside section 116A(1), which is about a process that ordinarily produces accurate records rather than about your memory of the page.

Bring the record that existed before the dispute did. Reviewing 2026 Employment Claims Tribunals decisions, Morgan Lewis notes the tribunal's warning that "high-level assertions, accounts supplied only after the event, or evidence from persons who did not directly observe the material events may carry less weight". Mediation runs on the same material that would decide the claim later.

In practice that means the employment contract and any variation, payslips and the salary records, the roster or shift system, the internal messages about performance or conduct, the HR portal entries and the message that communicated the dismissal. Most of it sits behind a company login that is closed on your last day, so capture it while you still have access, and remember TADM's own rule that a wrongful dismissal claim must be filed within one month of your last date of employment.

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

It 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 full TLS certificate chain. 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.
