Terms of Service

Last updated: January 2026

1. Service Description

SoulProp provides cryptographic timestamping services. When you seal a file, we encrypt it, request an RFC 3161 timestamp from an independent timestamp authority, and store the encrypted file. You receive a key file that is the sole means of decrypting your sealed content.

2. Key Responsibility

You are solely responsible for your key file. We do not store, backup, or have any means of recovering your decryption key. If you lose your key file, your sealed content cannot be recovered. We strongly recommend backing up your key file to multiple secure locations.

3. Payment and Refunds

Seal credits are non-refundable once purchased. Each credit allows you to seal one file. Credits do not expire. Payments are processed securely through Square.

4. Acceptable Use

You agree not to use SoulProp to seal content that is illegal, infringing, or harmful. While we cannot see the contents of your encrypted files, we reserve the right to terminate accounts that we reasonably believe are being used for unlawful purposes.

5. Data Storage

Sealed files are stored encrypted on secure infrastructure. We retain sealed files indefinitely unless you request deletion. Deletion requests require proof of key ownership.

6. Timestamps

RFC 3161 timestamps are provided by independent timestamp authorities. While we make every effort to ensure timestamp accuracy and availability, we do not guarantee the continued operation of third-party timestamp services.

7. Limitation of Liability

SoulProp provides timestamping services on an "as is" basis. We are not liable for any indirect, incidental, or consequential damages arising from your use of the service. Our liability is limited to the amount you paid for the specific seal in question.

8. Changes to Terms

We may update these terms from time to time. Continued use of SoulProp after changes constitutes acceptance of the new terms.
