We build practical tools for proving what a digital file was and when it existed, without requiring you to share the original content.
• A digital handoff should be independently verifiable by the recipient.
• Any change after handoff should be detectable.
• Proof should be repeatable: the same input always leads to the same verification result.
• Proof records: a cryptographic fingerprint and timestamp anchored in an immutable registry.
• Public verification pages and QR codes — share a link, not the file.
• Exportable evidence logs for reviews, audits, and disputes.
By default, we operate in hash-only mode. That is enough to verify integrity later without exposing the content itself.
If you attach metadata, keep it minimal and non-sensitive.
“Can I trust this file?” becomes a one-step check.
