Privacy Policy

Last updated November 2025.

This Privacy Policy explains how information is collected, used, and protected when you access the PlexiSign platform (the “Service”), which operates through email-based signing workflows and utilizes blockchain technology for verification records.

The Service is intentionally designed not to collect, store, process, or transmit any personal identifiable information (PII) or payment card information (PCI). By using the Service, you acknowledge and agree to the practices described in this Policy.

1. Information We Do Not Collect

The Service does not collect, store, or process any of the following:

  • Personal identifiable information (PII), including names, addresses, phone numbers, dates of birth, identification numbers, or other identifiable attributes
  • Payment card information (PCI), including card numbers, expiration dates, CVV/CVC codes, bank account information, or financial institution details
  • Sensitive or regulated personal information, including medical, biometric, or government-issued credentials

2. Information We May Collect

2.1 Technical and Operational Data

To operate the Service, we may collect limited non-identifying technical data such as:

  • Browser type, device type, and operating system
  • Generic usage and performance statistics
  • Non-identifiable log data such as network status
  • Session tokens used only for authentication and performance functionality

This information cannot be used to identify an individual and is retained only for technical operation and security monitoring.

2.2 Document Metadata and Hash Records

The Service may generate and store:

  • Cryptographic hash values
  • Timestamped blockchain transaction identifiers
  • Event logs related to system activity or signing actions

No readable document content is stored on the blockchain or accessible to the Company.

3. Blockchain Data Considerations

The Service may store verification metadata on a blockchain network. Blockchain entries are immutable and cannot be modified or deleted once published. These entries contain only anonymized cryptographic values and event timestamps, not document content or identity information.

4. How We Use Information

Collected data is used solely to:

  • Operate and improve the Service
  • Provide secure signature verification and audit logging
  • Protect system security and integrity
  • Support troubleshooting and performance optimization

We do not sell, rent, or trade any information to third parties.

5. Data Storage and Retention

Because the Service does not collect PII or PCI, retained data is limited to:

  • System logs for operational monitoring
  • Blockchain verification records

Retention periods comply with legal, regulatory, and system security needs.

6. Cookies and Tracking Technologies

The Service may use technologies only for:

  • Session handling
  • Security and authentication
  • Platform functionality

We do not use marketing, tracking, or advertising cookies.

7. Data Security

We implement industry standard safeguards including:

  • Encryption of data in transit
  • Access controls and authentication
  • System monitoring and auditing

While we work to protect platform integrity, no system is completely secure.

8. Third-Party Services

The Service may use third-party providers such as blockchain networks. These third parties cannot access document content or user identity data.

9. International Data Considerations

Technical data may be processed across regional server locations. By using the Service, you consent to such operational transfers.

10. Children’s Use

The Service is not intended for individuals who are not legally allowed to use this PlexiSign due to local or regional governing laws. We do not knowingly collect any information from children.

11. Changes to This Privacy Policy

We may modify this Policy from time to time. Changes are effective upon posting within the Service. Continued use indicates acceptance of updated terms.
