Two product lines. Stamp gives you tamper-evident timestamps — you keep the file. Vault adds full third-party file custody so a court-ready attestation is one click away.
Cryptographic timestamp + signed identity. We hold the receipt; you hold the file. Strong evidence of "first creation" in copyright disputes. Cheaper because we don't store your bytes.
Stamp plans prove the file existed at a moment in time. If you ever lose the original file, the receipt weakens. For full third-party custody, see Vault below.
We become your trusted custodian. Cleartext file held under our server custody, encrypted at rest with our master key. We can attest under oath, deliver under subpoena, and issue chain-of-custody PDFs that hold up in court. The same role a bank's safe deposit box plays — but for your IP.
All prices in USD. 2.9% + $0.30 Stripe processing applies (we don't surcharge it). Plan limits reset on the billing anniversary, not the calendar month.
No subscription required. Available to every plan, including Free, when you need the document for court or a publishing deal.
Everyone gets the full proof surface from day one. Higher plans buy more stamps, faster support, and the operational features that matter at scale — not "real" features you were missing.
Stamp plans notarize the existence of a file at a moment in time — only the hash + your signed identity lives on our server. Vault plans add full third-party custody: we hold the actual file in encrypted server storage so we can attest to it in court without you needing to produce the original.
Not always. A Stamp receipt + hash is admissible evidence (Federal Rule of Evidence 901) if you can produce the original file. Vault makes the case stronger and removes the "what if I lost the file" risk — we become a trusted custodian, like a bank safe-deposit box for your IP.
Yes. Free includes 10 stamps/month with hash-only proof — plenty to evaluate. Move up the Stamp ladder (Starter $19 → Team $99) for more stamps and tools. Move sideways to the Vault line ($79+) when you need third-party custody of the actual file.
Any successful POST /receipts — whether it's a contract, an IP stamp, or an attestation. Verifies, GETs, and reads don't count. Transfers of rights cost 1 stamp on top, refunded if declined.
Anytime, up or down. Prorated automatically. Cancellation doesn't delete your receipts — they stay verifiable forever.
Your receipts remain verifiable on DIONS 2.0 independently of us. The chain is the source of truth — we're the user-friendly layer on top. Vault customers get a 90-day export window where we hand back full file inventories.
