3.2 Cryptographic Integrity (SHA-256). VestedProof applies a SHA-256 hash to every document. This hash is immutable. If a document is modified after signing, the hash will change, and verification will fail.

3.3 Self-Verification Principle. VestedProof issues a digital Certificate that contains the necessary cryptographic proof. Documents can be verified independently using the VestedProof verification tools.

3.4 No Legal Advice. VestedProof provides the tools for signatures, not legal advice. The choice of signature type and suitability for specific transactions rests solely with the User.

4. SUBSCRIPTIONS, CREDITS, AND FINANCIAL TERMS

4.1 Pricing. Current pricing and plan features are available on our landing page at https://vestedproof.com or as part of your settings page https://app.vestedproof.com/settings. We offer various professional tiers.

4.2 Payment Processor. We use Stripe for all financial transactions. We do not store your full credit card information on our servers.

4.3 Pay As You Go Credits. Credits purchased under the Pay As You Go model do not expire as long as your Account remains active (at least one login every 12 months).

4.4 Automatic Renewal. Subscriptions automatically renew unless canceled. You authorize us to charge your payment method on file at the start of each renewal period.

4.5 Cancellation. You may cancel your subscription at any time. No refunds are provided for partial periods or unused credits, except as required by law.

5. USER CONDUCT AND PROHIBITED ACTIONS

5.1 Compliance with Laws. You agree to comply with all local, state, national, and international laws, including data privacy (GDPR, CCPA) and anti-spam regulations.

5.2 Prohibited Interference. You shall not attempt to bypass security features, distribute malware, misrepresent your identity, or use the Service for high-risk activities.

5.3 Document Content. VestedProof does not monitor document content. You are solely responsible for ensuring legality and appropriate rights.

6. DOCUMENT STORAGE, RETENTION, AND DELETION

6.1 Retention Policy. VestedProof stores documents and metadata only as long as your Account remains active or until you explicitly delete the document.

6.2 Deletion on Termination. Upon the closure of your Account, all associated Customer Data is permanently deleted from our primary servers for maximum privacy.

6.3 User Responsibility for Archival. It is your responsibility to download and securely store signed documents. VestedProof is not a permanent backup service.

7. INTELLECTUAL PROPERTY AND LICENSING

7.1 Ownership of Service. VestedProof and its licensors own all rights to the Service. No ownership is transferred to you.

7.2 Ownership of Documents. You retain 100% ownership of your documents. You grant us a limited license solely for the purpose of executing the signature request.

8. CONFIDENTIALITY AND DATA PROTECTION

8.1 Confidentiality. We implement industry-standard security measures to protect the confidentiality of your data.

8.2 Privacy Policy. Your use of the Service is also governed by our Privacy Policy, incorporated here by reference.

9. DISCLAIMERS OF WARRANTIES

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, VESTEDPROOF DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, AND WARRANTIES REGARDING THE LEGAL VALIDITY OF ANY SIGNATURE IN ANY SPECIFIC JURISDICTION.

10. LIMITATION OF LIABILITY AND INDEMNIFICATION

11. GOVERNING LAW AND DISPUTE RESOLUTION

11.1 Governing Law. This Agreement is governed by the laws of the State of Delaware, USA, without regard to conflict of law principles.

11.2 Jurisdiction. Any dispute arising from these Terms or the Service shall be resolved exclusively in the courts located in Delaware, USA.

12. MISCELLANEOUS

12.1 Severability. If any provision is found invalid, the remaining provisions remain in full force.

13. DETAILED DOCUMENT LIFECYCLE MANAGEMENT

13.1 Upload and Hashing Protocol. When a User uploads and send a document by VestedProof, our system immediately generates a SHA-256 fingerprint. This fingerprint is used as the foundational anchor for all subsequent signature operations. The hashing process ensures that the document content remains immutable.

13.2 Invitation and Signature Phase. Upon initiating a signature request, invitations are sent via transactional email (Postmark) to the designated signatories. Signatories must complete the verification challenges (SES or AdES) before applying their cryptographic signature.

13.3 Finalization and Certification. Once all parties have applied their signatures, VestedProof generates the final signed PDF and the Certificate of Completion. The Certificate contains the complete audit trail and technical metadata required for independent verification.

13.4 Archival and Deletion Strategy. As specified in Section 6, VestedProof is not a permanent storage service. Documents are maintained only as long as the User Account is active or until the User manually deletes them. Deleting an account or a specific document results in the permanent removal of the document and all associated signatures from our primary storage.

14. CRYPTOGRAPHIC SIGNATURE PROTOCOL (DEEP DIVE)

VestedProof implements a multi-layered cryptographic protocol to ensure the authenticity and non-repudiation of every electronic signature:

14.1 Signer Identification. For Simple Electronic Signatures (SES), identity is verified through a unique, one-time link sent to the signatory's email. For Advanced Electronic Signatures (AdES), an additional layer of verification is added, typically through an SMS-based two-factor authentication (2FA) code or other multifactor mechanisms.

14.2 Technical Linkage. Every signature is cryptographically linked to the specific Document Hash. This ensures that the signature is only valid for that specific version of the document. Any modification to the document after the signature has been applied will break this link, rendering the signature invalid.

14.3 Immutable Audit Trail. The VestedProof engine records every technical event associated with the document. This includes the IP address of the signer, the browser "fingerprint" (user-agent), the exact timestamp (UTC), and the success or failure of various verification challenges.

15. GLOBAL LEGAL DEFENSIBILITY AND COMPLIANCE STANDARDS

VestedProof is designed to provide "Strong Evidence" in legal proceedings across various jurisdictions:

15.1 United States (ESIGN and UETA). Our workflows comply with the federal Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA) as adopted by and applied in the State of Delaware.

15.2 European Union (eIDAS). VestedProof facilitates compliance with the eIDAS Regulation (EU No 910/2014) for both Simple (SES) and Advanced (AdES) electronic signatures. Note that VestedProof does not currently provide Qualified Electronic Signatures (QES).

15.3 Commonwealth Countries. Our signature protocols are designed to meet the standards set in the Electronic Transactions Acts of Australia, the United Kingdom, Canada, and Singapore.

16. USER TRAINING AND PROTOCOL FOR ENTERPRISE CLIENTS

To maximize the benefits of the VestedProof platform, we recommend the following protocols for our enterprise and professional users:

16.1 Internal Policy Alignment. Users should ensure that their internal document management policies are updated to reflect the use of electronic signatures and the Self-Verifying architecture of VestedProof.

16.2 Security Awareness for Signatories. Users are encouraged to inform their signatories about the importance of secure email and SMS practices to maintain the integrity of the signature process.

16.3 Audit Trail Management. We recommend that Users download and archive the Certificate of Completion for every finalized document to ensure they have the necessary evidence for any future legal audits or disputes.

17. ACCESSIBILITY AND INCLUSIVITY COMMITMENT
