Terms of Service

Last updated: November 12, 2025

1. Acceptance of Terms

By accessing or using ProveChain (the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree with any part of these Terms, you may not use the Service.

These Terms apply to all users of the Service, including both free and paid tiers.

2. Service Description

ProveChain provides cryptographic timestamping and proof-of-authorship services for source code. The Service includes:

  • Free Tier: CLI tool and Web UI for local file hashing (MIT licensed)
  • Paid Tiers: Cloud storage, blockchain timestamping, proof history, and analytics

3. User Responsibilities

You agree to:

  • Provide accurate information when creating an account
  • Use the Service only for lawful purposes
  • Not upload malicious code, viruses, or harmful content
  • Not attempt to reverse engineer, hack, or circumvent security measures
  • Maintain your own backups of proof files

4. Intellectual Property

Your Content: You retain all rights to your source code. ProveChain only stores cryptographic hashes (SHA-256 fingerprints), not your actual source code.

Our Service: The ProveChain CLI is open-source under the MIT License. The web application, API, and backend services are proprietary and owned by Aramantos.

5. Pricing and Payments

5.1 Free Tier

The CLI and Web UI are free forever with no usage limits.

5.2 Paid Tiers

  • Founding Member: €5/month (locked forever for first 100 users)
  • Pro: €9/month (standard tier)

5.3 Billing

Subscriptions are billed monthly via Stripe. Prices are in EUR and exclude VAT (if applicable). No refunds after 14 days.

6. Privacy and Data Collection

Your use of ProveChain is subject to our Privacy Policy. Key points:

  • We collect minimal data (email, proof metadata, payment info)
  • We do NOT store your source code (only file hashes)
  • We comply with GDPR (right to access, deletion, portability)
  • Free tier: Zero data collection (everything runs locally)

7. File Immutability and Preservation Requirements

⚠️ CRITICAL: Your Proofs Depend on Unchanged Files

Each cryptographic proof is permanently locked to the exact file versions that existed when you created it. If you modify, overwrite, or delete the original files, the proof becomes invalid and worthless.

7.1 Your Responsibilities

To maintain proof validity, you MUST:

  • Preserve Original Files: Keep exact file versions used for each proof unchanged and accessible
  • Store All Versions Separately: If you have multiple proof versions, maintain separate copies for each
  • Never Overwrite: When updating your work, create copies instead of modifying originals
  • Use "New Version" Feature: Create new proof versions instead of editing files in place

7.2 Consequences of File Modification

If you modify original files after proof creation:

  • The proof hash will not match current file state
  • Verification will fail
  • The proof has no legal value
  • You cannot retroactively "fix" the proof

7.3 Our Liability

ProveChain stores cryptographic hashes only - NOT your actual files. We are NOT responsible for: files you modify, delete, or overwrite; loss of original file versions; failed proof verification due to file changes; or legal disputes caused by missing or modified files.

You are solely responsible for preserving original files. Without them, your proofs are worthless.

8. Disclaimers and Warranties

IMPORTANT LEGAL DISCLAIMER

ProveChain is provided "AS IS" without warranties of any kind. We do not guarantee that proofs will be accepted as legal evidence in all jurisdictions.

We disclaim all warranties, express or implied, including:

  • Fitness for a particular purpose
  • Non-infringement
  • Uninterrupted or error-free service
  • Accuracy or reliability of results

9. Limitation of Liability

LIMITATION OF LIABILITY

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID US IN THE 12 MONTHS PRECEDING THE CLAIM, OR €100, WHICHEVER IS LOWER.

We are not liable for any indirect, incidental, consequential, or punitive damages, including lost profits, data loss, or business interruption.

10. Termination

10.1 By You

You may cancel your subscription anytime from your account dashboard.

10.2 Founding Member Grace Period

Special Benefit for Early Supporters

Founding Members have 30 days after cancellation to reactivate at the €5/month rate. After 30 days, resubscription is at the current Pro rate (€9/month or higher).

Example: Cancel on Jan 1 → Reactivate by Jan 31 at €5/month → After Jan 31, Pro rate applies.
