Questions people ask before certifying proof.
Is this eIDAS-compliant?
Yes. Every certificate package includes a qualified timestamp under RFC 3161 and an advanced electronic signature compliant with EU Regulation 910/2014 (eIDAS). This gives the evidence legal standing in all EU member states — no extra steps or local legal requirements to retrofit.
Why not just take a screenshot?
Screenshots can be edited, contain no independent metadata, and are routinely challenged. A certificate package adds SHA-256 hashes, RFC 3161 timestamp responses, full metadata, and a signed manifest — everything needed to verify the evidence without relying on your word.
What do I receive?
A PDF certificate, metadata ZIP, timestamp request/response files, manifest signature, and the source artifact such as a file or browser recording.
Can I certify private or logged-in content?
For web content that requires interaction, use the browser session flow. It opens an isolated browser session that you control from the web app.
Is this court-ready legal advice?
No. The service creates technical proof artifacts. Discuss admissibility and legal strategy with a qualified lawyer in your jurisdiction.
Need proof before it disappears?
