Terms of Service

The service#

LKP lets people prove facts about themselves (such as being over a certain age) with zero-knowledge proofs, and lets businesses request and check those proofs. See the Privacy Policy for how data is handled.

Test mode. This deployment issues credentials from sandbox data. Verifications don't establish anything about real people and must not be relied on for compliance, age-gating or any other real-world decision.

Wallet users#

• Only verify documents and accounts that are yours, and don't share, sell or lend your wallet or credentials.
• You are responsible for your passkey, passphrase and recovery kit. We can't read or restore your wallet; if you lose all of them, your credentials are gone.
• We may revoke credentials obtained by fraud or issued in error.

Business customers#

• Keep your API keys and webhook secrets confidential, and confirm results on your server as described in the documentation.
• Only request the facts you need, tell your users why, and comply with the laws that apply to your use, including data-protection and age-verification rules. An LKP check does not, by itself, satisfy any particular regulation.
• Don't use LKP to track people across services, to discriminate unlawfully, or to try to re-identify users.
• Don't probe, overload or circumvent the service's security or rate limits.
• You can close your account at any time from the console. We may suspend accounts that break these terms.

What a proof shows, and what it does not#

A verified session means a zero-knowledge proof confirmed that a credential signed by this deployment's issuer satisfies the checks you requested, that it has not expired or been revoked, and that it is bound to the wallet that produced the proof. Facts in a government-ID credential are those Didit extracted from the document (nationality as citizenship on the document, not current physical location).

The proof does not independently re-examine the original document, does not establish that the person at the keyboard is the document holder, and does not guarantee legal or regulatory compliance out of the box. Duplicate-enrolment controls apply per verified document, number or account. They are not a universal biometric ID across every identity a person might hold.

Availability and changes#

We aim to keep LKP available but provide it “as is”, without warranties of uninterrupted or error-free operation. We may change or discontinue features, and will give business customers reasonable notice of material changes.

Liability#

To the extent the law allows, we are not liable for indirect or consequential losses, and our total liability for any claim is limited to the fees you paid us in the 12 months before it arose. Nothing in these terms limits liability that can't be limited by law.
