Security

Secure by design

Doc Sign Flow keeps your agreements private, verifiable, and trustworthy — from encrypted storage to tamper-evident signed PDFs.

Protection at every step

Encryption & private storage

Documents live in a private bucket and are served only through short-lived, signed links.

Access control

Row-level security ensures only a document's owner — and the right signers — can ever reach it.

Audit trail

Every action is recorded with timestamps and IP addresses for a defensible record.

Completion certificates

Each finished PDF is sealed with a SHA-256 hash and a certificate of completion.

Data privacy

Secrets stay server-side, never exposed to the browser. We don't sell your data.

Compliance-ready

Workflows designed to grow toward ESIGN, UETA, eIDAS, and GDPR readiness.

Legal frameworks we build toward

Electronic signatures are recognized under various laws depending on where you operate.

ESIGN Act (US)

Consent + intent + associated record.

UETA (US states)

Electronic records & signatures parity.

eIDAS (EU)

Electronic, advanced & qualified tiers.

IT Act (India)

Recognition of electronic records.

This platform provides electronic signing tools but does not provide legal advice. Users are responsible for ensuring their documents comply with local laws.

Security FAQ

Where are documents stored?+

In a private storage bucket protected by row-level security. Downloads use short-lived signed URLs, never public links.

How do you prevent tampering?+

Each completed PDF is sealed with a SHA-256 hash recorded in the audit trail, so any change to the file is detectable.

Can I restrict who opens a document?+

Yes — add an access code and/or require email OTP verification before a signer can view a document.

Are you a Qualified Trust Service Provider?+

Not yet. Advanced identity verification and qualified signatures are on the roadmap. For high-assurance or regulated use, consult a qualified professional.
