Terms of Service

By using Signature Identifier you agree to these terms. If you don’t, please don’t use the service.

Signature Identifier is an AI-assisted reading tool for handwritten signatures. It drafts a structured dossier (signer, period, medium, market, preservation, etc.) and, when a reference image is supplied, runs a side-by-side similarity comparison.

Signature Identifier is not an authentication service. Readings are AI-generated opinions and may be wrong — sometimes confidently wrong. Do not make legal, financial, purchase, or forensic decisions based on a dossier alone. Route signatures with real weight through PSA, JSA, Beckett, or a certified document examiner.

You agree to:

• Only upload content you have the right to submit.
• Not misuse the service or attempt to bypass its limits.
• Not upload unlawful, harmful, or abusive content.
• Respect the intellectual property rights of others.

You retain ownership of images you upload. By submitting, you grant us the limited license we need to process the images, generate a dossier, store the result, and — if you mark the dossier public — display it in the community archive. Our software, models, and brand remain ours.

Signature Identifier is provided “as is” without warranties. We are not liable for damages arising from your use of the service, including reliance on a dossier or a comparison verdict.

We may update these terms. Continued use after changes means you accept the new terms.
