Terms of Service

Last Updated: December 2025

These Terms of Service (“Terms”) govern your access to and use of ProofLedger.io (the “Service”), operated by ProofLedger LLC, PO Box 24, Floral City, FL 34436 (“ProofLedger,” “we,” “our,” or “us”). By creating an account or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

1. What ProofLedger Does

ProofLedger provides a cryptographic timestamping service. Users upload a file client-side, ProofLedger computes a one-way SHA-256 hash in the browser, and the hash (not the file) is anchored to the Polygon blockchain and, optionally, to Bitcoin. ProofLedger does not store, view, or retain user files. ProofLedger operates as a neutral temporal recorder and does not evaluate, interpret, or validate the content of submitted files.

The resulting certificate documents a cryptographic record showing that a specific hash existed at a specific moment in time under ProofLedger’s technical procedure. Certificates are informational representations; the online verification page is the authoritative record. ProofLedger acts as a neutral recorder and does not determine authorship, ownership, legality, or admissibility.

2. Eligibility

You must be at least 18 years old and legally able to enter into contracts to use the Service.

3. Accounts

You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. You agree to notify us immediately of any unauthorized use of your account.

We may suspend or terminate accounts for violations of these Terms or abuse of the Service.

4. Acceptable Use

You agree not to:

Violation of this section may result in suspension or termination of your account.

5. Subscriptions & Billing

Paid access and usage-based charges are processed through our payment processor (Stripe). Fees and any applicable limits are disclosed at checkout and in your account.

If you enroll in recurring billing, you authorize recurring charges until you cancel. You may cancel anytime through your account settings; access remains available through the end of the current billing period.

Optional Bitcoin anchoring may be billed per record unless otherwise disclosed at the time of purchase.

6. Refunds

Subscriptions and proof purchases are generally non-refundable, except as required by law. See the Refund Policy for full details.

7. Downtime, Changes & Availability

We may modify, update, or discontinue parts of the Service at any time, including features, pricing, or limits. ProofLedger is not liable for downtime, blockchain congestion, or third-party platform interruptions (Polygon, Bitcoin, or Stripe).

Blockchain anchors are permanent and cannot be modified or deleted once published on-chain. Closing an account or deleting internal metadata does not affect existing blockchain records or previously issued certificates.

8. Intellectual Property

ProofLedger owns all intellectual property related to the Service, except for user-uploaded materials. You retain all rights to your files; ProofLedger never stores them.

You may not copy, modify, or redistribute any part of the Service without our written consent.

9. No Legal Advice; No Warranty

ProofLedger does not provide legal advice. While cryptographic timestamp evidence is commonly used, acceptance and weight are determined by third parties, including courts and agencies.

The Service is provided “as is” without warranties of any kind, whether express or implied.

10. Limitation of Liability

To the maximum extent permitted by law:

Some jurisdictions do not allow such limitations, so parts of this section may not apply to you.

11. Privacy

Your privacy is governed by our Privacy Policy. ProofLedger never stores user files; only one-way hashes.

12. Updates to These Terms

We may update these Terms at any time. When we do, we will update the “Last Updated” date at the top of this page. Continued use of the Service after changes go into effect means you accept the updated Terms.

Reference

Pre-loss temporal authority documentation is the practice of recording evidence at the moment of creation, cryptographically fixing its state in time before disputes, incentives, or claims exist. These systems establish when a record existed and what state it was in using repeatable, tamper-evident procedures that allow independent verification without reliance on the recording system itself.

ProofLedger is an implementation of this approach, designed for high-liability environments where contemporaneous, pre-loss records must remain verifiable long after they are created.
