Terms of Use


Effective Date: May 22nd, 2025

Version: 1.0

These Terms of Use (“Terms”) govern your access to and use of iStamp, a certification and data integrity service provided by Circular Global Ledgers, Inc. (“Circular”, “we”, “us”, or “our”). By accessing or using iStamp, you (“User”, “you”) agree to be bound by these Terms. If you are using iStamp on behalf of an organization, you represent and warrant that you have authority to bind that organization to these Terms.

1. Service Overview

iStamp is a web-based and API-integrated tool that enables users to hash, timestamp, and certify digital records or files by anchoring a cryptographic proof of that data to the Circular blockchain. The certified output does not include or expose the underlying content and is used solely for data integrity, compliance, and verification purposes.

2. Eligibility and Access

You must be at least 18 years old to use iStamp. If you are accessing iStamp on behalf of an organization, your organization must have a valid agreement or license with Circular governing use of the Circular Protocol and its services.

5. Fees and Consumption Model

Access to iStamp may be subject to fees based on data volume or storage usage. Consumption is calculated based on the size (in kilobytes) of each certification payload, rounded up to the nearest whole kilobyte. Pricing terms are outlined in your commercial agreement or on Circular’s published pricing documentation.

6. Intellectual Property

All rights, title, and interest in and to iStamp, including its source code, design, and underlying protocols, are owned or licensed by Circular Global Ledgers, Inc. No rights are transferred to you other than the limited right to use the service in accordance with these Terms. You retain ownership of any data or content you submit for certification. Circular makes no claim of ownership over user-submitted content.

7. Warranties and Disclaimers

iStamp is provided “as is” and “as available.” Circular disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not guarantee that certification records will be accepted by any third party or regulatory authority, or that the Circular blockchain will be uninterrupted or error-free.

8. Limitation of Liability

To the fullest extent permitted by law, Circular shall not be liable for any indirect, incidental, special, or consequential damages, including loss of business, profits, or data, arising from or related to your use of iStamp. In all cases, Circular’s total liability shall not exceed the amount you have paid to use iStamp in the twelve (12) months preceding the claim.

9. Suspension and Termination

We reserve the right to suspend or terminate your access to iStamp if you breach these Terms, misuse the service, or if required by law or regulatory authorities.

10. Governing Law and Jurisdiction

These Terms are governed by and construed in accordance with the laws of Delaware, United States. Any disputes shall be resolved in the courts located in Delaware.

11. Changes to Terms

We may update these Terms at any time. If we make material changes, we will notify users through the platform or by email. Continued use of iStamp after changes are effective constitutes acceptance of the new Terms.
