Terms of Service

Effective Date: November 2025

Welcome to SignaSeal, a blockchain-verified digital signature platform for creating, sharing, and signing legal agreements including Non-Disclosure Agreements (NDAs), Freelance/Contractor Agreements, Employment Terms Agreements, and other professional contracts.

By accessing or using SignaSeal, you agree to these Terms of Service ("Terms"). If you do not agree, please do not use the platform.

1. Service Description

SignaSeal enables users to:

  • Create and manage legal agreement templates including NDAs, freelance contracts, employment terms, and custom agreements (both personal and global templates);
  • Electronically sign agreements using typed or drawn signatures;
  • Share unique, secure links for multi-party signing;
  • Store, archive, and retrieve completed documents (subject to service tier and storage limits);
  • Verify document integrity using cryptographic hashing (SHA-256);
  • Timestamp document hashes on the Bitcoin blockchain via OpenTimestamps for immutable proof of existence;
  • Receive automated email notifications regarding document status; and
  • Generate comprehensive audit trails for signed agreements.

The service is provided "as-is" for lawful business and personal use.

2. Eligibility

You must be at least 18 years old and capable of entering into binding contracts under applicable law.

3. Account & Authentication

You may sign in using GitHub or Google credentials. You are responsible for maintaining the security of your account and ensuring that your sign-in email matches the address you intend to associate with your signatures.

4. Electronic Signatures

By typing your name, drawing your signature, or otherwise confirming within the SignaSeal interface, you consent to the use of electronic signatures under the EU eIDAS Regulation and equivalent electronic signature laws. Each signed document will be considered legally binding to the same extent as a handwritten signature, provided all parties consent to electronic execution.

5. Confidentiality & Data Handling

All documents created or uploaded remain private to the parties involved. SignaSeal does not claim ownership of user content. Documents are stored securely and are accessible only to authenticated parties to an agreement. For more details on how we handle your data, please see our Privacy Policy.

6. Email Notifications

SignaSeal sends automated email notifications to parties involved in agreements, including but not limited to:

  • Confirmation emails when you create and sign a document;
  • Invitation emails to other parties requesting their signature;
  • Status updates when all parties have signed.

By using SignaSeal, you consent to receive these transactional emails, which are essential to the service's operation. You cannot opt-out of these notifications as they are necessary for contract execution. Emails are sent via our third-party email service provider.

7. Document Integrity & Blockchain Verification

Once all parties have signed an agreement, SignaSeal:

  • Generates a cryptographic hash (SHA-256) of the final document, serving as a digital fingerprint;
  • Timestamps this hash on the Bitcoin blockchain via OpenTimestamps, creating immutable, independently verifiable proof that the document existed at a specific time;
  • Stores the blockchain timestamp proof with the agreement for future verification.

Blockchain timestamping typically confirms within 1-2 hours as the Bitcoin network processes the transaction. You may use the "Verify Document Integrity" and "Verify Blockchain Timestamp" features at any time to confirm the document's authenticity and immutability. This provides cryptographic proof beyond traditional e-signatures.

Important: Blockchain verification is provided via OpenTimestamps, a free, open-source service. While highly reliable, blockchain confirmation times depend on Bitcoin network activity and are not guaranteed to be instant.

8. Templates

SignaSeal provides:

  • Global Templates: Pre-built templates available to all users, which cannot be modified or deleted by individual users;
  • Personal Templates: Custom templates you create, which are stored privately in your account and can be edited or deleted at your discretion.

You are solely responsible for the content and legal validity of any custom templates you create.

9. Share Links & Security

When you create an agreement, SignaSeal generates a unique, secure share token that allows other parties to access and sign the document. Share links should be transmitted only to intended recipients via secure channels. Anyone with access to a share link can view and sign the associated document. Once all parties have signed, share links expire and can no longer be used to modify the agreement. You are responsible for the confidentiality of share links before document completion.

10. Document Archiving

You may archive completed agreements to organize your document library. Archived documents remain accessible and can be unarchived at any time. Archiving does not delete or modify the document's legal status.

11. Acceptable Use

You agree not to:

  • Use SignaSeal for unlawful, defamatory, or fraudulent purposes;
  • Share malicious or copyrighted content without permission;
  • Attempt to access another user's documents or credentials;
  • Misuse share links or attempt to circumvent security measures.

12. Intellectual Property

All platform code, logos, and trademarks belong to the SignaSeal team. Users retain all rights to their documents and signatures.

13. Service Tiers & Storage

SignaSeal offers different service tiers:

  • Free Tier: Unlimited agreement creation and signing. Documents can be downloaded immediately after signing. Dashboard storage is not included in the free tier.
  • Paid Storage Tiers: Store agreements in your dashboard for long-term access, re-verification, and organization. Storage limits and pricing vary by tier.

Free tier users must download their signed agreements immediately, as documents may not be accessible via the dashboard after the signing session ends. Paid tier users can store, search, filter, and re-verify agreements anytime.

We reserve the right to modify pricing and tier features with reasonable notice (typically 30 days). Existing paid subscribers will be notified of any price changes before renewal.

14. Disclaimers & Limitations

Not Legal Advice: SignaSeal provides tools for creating and signing legal agreements but does not provide legal advice. We are a technology platform, not a law firm.

Template Disclaimer: Global templates provided by SignaSeal are designed with international best practices and include compliance provisions for common jurisdictions (eIDAS, ESIGN, GDPR). However:

  • Templates are provided for convenience only and do not constitute legal advice;
  • You are solely responsible for ensuring any agreement you create is legally enforceable in your jurisdiction;
  • Contract law varies significantly by country, state, and industry;
  • Employment agreements, in particular, must comply with local labor laws which vary widely;
  • We strongly recommend consulting a licensed attorney in your jurisdiction before relying on any agreement for high-value transactions, employment matters, or IP protection.

Verification Limitations: Document integrity and blockchain verification features validate technical authenticity (that the document hasn't been tampered with) but do not:

  • Guarantee legal enforceability of the agreement's content;
  • Verify the identity of signers beyond their authentication method (GitHub, Google OAuth);
  • Constitute notarization or legal authentication by a government authority;
  • Replace jurisdiction-specific requirements for contract validity.

User Responsibility: You are solely responsible for:

  • The content and legal validity of custom templates you create;
  • Ensuring agreements comply with applicable laws in your jurisdiction;
  • Verifying that all parties have legal capacity to enter the agreement;
  • Obtaining proper legal counsel for complex or high-value agreements.

15. Indemnification

You agree to indemnify, defend, and hold harmless SignaSeal, its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, and expenses (including reasonable legal fees) arising out of or in any way connected with:

  • Your use or misuse of the service;
  • Your violation of these Terms;
  • Your violation of any third-party rights, including intellectual property rights;
  • The content of agreements you create, including any claims that such content is unlawful, defamatory, or infringes third-party rights;
  • Disputes arising from agreements you create or sign using the service;
  • Your breach of applicable laws or regulations.

This indemnification obligation survives termination of your account and your use of the service.

16. Limitation of Liability

To the fullest extent permitted by law, SignaSeal and its contributors will not be liable for indirect, incidental, or consequential damages arising from use of the service, including but not limited to: loss of data, unauthorized access via compromised share links, email delivery failures, blockchain confirmation delays, disputes arising from signed agreements, or unenforceability of agreements due to jurisdiction-specific legal requirements.

SignaSeal's total liability for any claim related to the service shall not exceed the amount paid by you (if any) for the service in the 12 months preceding the claim.

17. Termination

We may suspend or terminate access if you breach these Terms or misuse the service. Upon termination, your documents may be retained for legal compliance purposes but will no longer be accessible through your account unless required by law or for agreements involving other parties.

You may terminate your account at any time. Termination does not affect the legal validity of agreements you've already signed, as other parties may retain copies and blockchain timestamps remain permanently recorded.

18. Governing Law

These Terms shall be governed by the laws of Ireland and the European Union (GDPR) framework. Any disputes shall be resolved in the courts of Dublin, Ireland.

19. Changes to Terms

We may update these Terms periodically to reflect changes in our services, legal requirements, or business practices. Significant changes will be announced via email or prominent notice on the platform. Continued use of SignaSeal after changes constitutes acceptance of the updated Terms.
