Acceptable Use Policy

Last Updated: July 24, 2026

Overview

This Acceptable Use Policy ("AUP") governs your use of the kysigned service operated by Kychee, Inc. Violation of this policy may result in suspension or termination of your access.

Permitted Uses

kysigned is designed for legitimate e-signature needs where electronic signatures are legally permitted in the user's jurisdiction. Common examples include:

You are responsible for confirming that electronic signatures are legally valid for your specific document type, in your jurisdiction, and in any other jurisdiction where the document will be used or enforced. See "Excluded Document Types" below for examples of common restrictions.

Prohibited Uses

You may NOT use kysigned to:

Spam, unsolicited, or deceptive sending

A signing request may be sent only to people who are expecting it — parties with whom you have a genuine agreement or dealing, who have a reason to receive your document for signature. Specifically, you may not:

These are severe violations. We may immediately and without notice revoke the sending account, void the affected signing requests, and report the activity to the appropriate authorities, including law enforcement and anti-fraud or anti-spam bodies.

Illegal or Harmful Content

Excluded Document Types

Important — your responsibility: kysigned is available globally. Electronic signature laws vary significantly by jurisdiction. It is YOUR responsibility to determine whether the document you want to sign is legally allowed to be signed electronically in the jurisdiction(s) where the parties are located and where the document will be used or enforced. kysigned does not provide legal advice and cannot determine this for you. When in doubt, consult a qualified attorney in your jurisdiction.

The following are non-exhaustive examples of document types that are commonly excluded from electronic signing under various legal frameworks. Do not submit these document types to kysigned unless you have confirmed that electronic signing is legally permitted in your specific jurisdiction.

United States (ESIGN Act / UETA — federal law, with state variations):

European Union (eIDAS Regulation, with member-state variations): The EU recognizes three signature levels: Simple, Advanced, and Qualified Electronic Signatures (QES). kysigned signatures meet the technical bar for Advanced Electronic Signatures (AES), but kysigned is NOT a Qualified Trust Service Provider and does NOT produce Qualified Electronic Signatures. Document types that typically require QES under EU member-state law include:

The exact list varies significantly by member state. EU users must research their own member state's requirements before signing legally significant documents with kysigned.

Other jurisdictions (non-exhaustive):

Signers' jurisdictions matter too: If your document will be signed by parties in different countries, the most restrictive jurisdiction's rules apply for that signer's portion. Cross-border enforceability is a separate question — consult an attorney.

General rule: if the document type requires notarization, witnessing, or a court-appointed official under your local law, kysigned is probably not the right tool. kysigned is designed for everyday business agreements (contracts, NDAs, leases, freelance agreements, internal approvals), not for documents that require formal legal ceremony.

System Abuse

Misrepresentation

Enforcement

We may, at our sole discretion:

A signing record that has already been delivered to its recipients cannot be recalled or modified by us, even in cases of policy violation — once delivered, a signing record is in each recipient's own mailbox.
