Important Legal Notice

This service provides:

  • ✓ Cryptographic proof that a file with a specific hash existed at a recorded time
  • ✓ A timestamped certificate for your records
  • ✓ Public verification of the timestamp

This service does NOT:

  • ✗ Register your copyright with any government agency
  • ✗ Provide legal advice or legal representation

To sue for copyright infringement in US courts, you must register with the US Copyright Office. This timestamp service provides supplementary evidence, not a substitute for registration.

Frequently Asked Questions

Is my file uploaded to your servers?

No. We calculate the hash (fingerprint) in your browser and only store that hash. Your actual file never leaves your computer.

What can I timestamp?

Any digital file: writing, art, music, code, designs, photos, videos, etc. We support all major file formats.

Is this legally valid?

Timestamps can serve as evidence in copyright disputes, but they don't replace official registration. Consult a lawyer for legal advice.

How much does it cost?

Completely free. Forever. No hidden fees, no subscriptions.

Can I timestamp multiple versions?

Yes! Each version gets its own unique timestamp. This helps prove the evolution of your work.

What if I lose my certificate?

You can retrieve it anytime using your access code and the verification link.
