U.S. ESIGN Act and UETA
The U.S. Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA) each require four conditions for a valid electronic signature: (a) intent to sign, (b) consent to do business electronically, (c) association of the signature with the record, and (d) retention of records. Nota Sign ensures compliance with these requirements under U.S. ESIGN and UETA laws.
EU eIDAS
The Regulation on Electronic Identification and Trust Services for Electronic Transactions (eIDAS, Regulation (EU) No 910/2014) defines three types of electronic signatures—Simple Electronic Signature (SES), Advanced Electronic Signature (AES), and Qualified Electronic Signature (QES)—and establishes a legal framework for electronic signatures in EU. The UK continues to apply this framework through the retained UK eIDAS. As the highest-level electronic signature, QES has legal effect equivalent to a handwritten signature in accordance with Article 25 of eIDAS. Nota Sign supports the provision of QES-level signature services.

Nota Sign has obtained the ISO/IEC 27001 and ISO/IEC 27701 certifications which fully demonstrate Nota Sign’s firm commitment to customer information security and its proactive and forward-looking practices in protecting personal information.

GDPR
The EU's General Data Protection Regulation (GDPR) aims to protect the "fundamental rights and freedoms of European citizens, in particular the right to the protection of personal data". Nota Sign is committed to strictly complying with the requirements of GDPR.
CCPA
The California Consumer Privacy Act (CCPA) of the United States establishes privacy rights for California residents and regulates corporate data processing activities (effective on January 1, 2020, and amended by the CPRA on March 29, 2023). As the first consumer privacy law in the United States, its stringency is equivalent to that of the EU's GDPR. Nota Sign is committed to strictly complying with the requirements of the CCPA.
Nota Sign’s priority is to ensure that your experience is both safe and secure.
