Your documents are safe with us
Bank-grade protection at a fair price. Cheap doesn't mean careless — security is the floor at sign.pink, not a premium tier.
Encryption everywhere
Your documents are encrypted in transit with TLS 1.3 and at rest with AES-256. Nobody sees them in the clear.
Signer authentication
Verify signers by email link, with optional access codes. Every signature is attributed to the person who made it.
Tamper-evident sealing
Once a document is signed, it's cryptographically sealed. Any change after the fact is instantly detectable.
Secure retention
Completed documents and their audit trails are stored securely and stay downloadable for both parties.
Privacy by default
We never sell your data or mine your contracts. You control who gets a link and when.
Reliable infrastructure
Built on resilient, backed-up infrastructure so your documents are there when you need them.
Secure and legally binding. Learn why e-signatures hold up in court, or read about our tamper-evident audit trail.
Security FAQ
No. Documents are encrypted at rest and in transit, and only the people you explicitly send a link to can access a document. We don't sell data or mine your contracts.
