Frequently asked questions

The European eIDAS regulation recognizes certain timestamps as having the same legal value as a notarized act. Sectigo's RFC 3161 timestamp is qualified under ETSI EN 319 422, giving it maximum probative force before European courts.

Bitcoin anchoring mathematically proves the anteriority of a document — verifiable by anyone, without a trusted third party. For most uses (intellectual property, ideas, correspondence) it is more than sufficient. For contracts, the Pro version adds European legal recognition.

Yes, with no commitment or fees. Cancellation takes effect at the end of the current period. Your Pro proofs remain accessible and verifiable even after cancellation.

Proxae never receives your raw content — the hash is computed in your browser (SubtleCrypto). For Pro encrypted content, AES-256-GCM encryption is performed client-side before upload. We cannot read your data.

A REST API is available for integrations. Contact us for enterprise needs and high volumes.

Identity verification is entirely optional — Proxae does not need it to work. It is there for you: once your identity is certified via Stripe Identity, your name is cryptographically linked to your proof and appears in the PDF certificate. In the event of a dispute, you can prove that it was you — and no one else — who performed this certification on that date.
