Terms of Service

These Terms of Service ("Terms") are an agreement between you and WordKey Inc., a Delaware corporation ("WordKey", "we", "us"). By creating a word, joining the waitlist, opening a business account, or integrating the WordKey SDK, you agree to these Terms.

WordKey is a single-word universal authentication protocol. Consumers authenticate to participating sites with a personal word bound to their device; businesses integrate the Word? button and verify authentications through the WordKey API and SDK. WordKey uses a zero-knowledge design: your word is never stored by WordKey in recoverable form.

• Your word is personal to you. Keep it confidential — anyone with your word and an approved device can act as you on participating sites.
• You are responsible for the devices you bind to your word. If a device is lost or you believe your word has been exposed, rotate your word promptly in the app.
• The consumer service is free for individuals.

You agree not to:

• attempt to authenticate as, or gain access to the account of, another person;
• probe, disrupt, overload, or circumvent the security of the service (see our Security Disclosure policy for authorized research);
• use the service to violate law, infringe others' rights, or transmit malicious code;
• resell, sublicense, or misrepresent your affiliation with WordKey; or
• scrape, harvest, or reverse-engineer the protocol except as permitted by law.

We may suspend or terminate accounts that violate these Terms.

• Business account holders receive API keys, which are confidential. You are responsible for all activity under your keys and must notify us promptly of any suspected compromise.
• You must present the Word? button and WordKey marks accurately and may not imply endorsement beyond your integration.
• You are responsible for your own application, including how you handle user data you collect after a WordKey authentication.

• Pay-per-auth: the first 10,000 successful authentications each month are free; usage beyond that is billed at the published per-authentication rate. Failed attempts are never billed.
• Flat-rate plans: billed monthly in advance at the published rate. Plan changes take effect immediately; fees for the current period are not prorated unless stated otherwise.
• Payments are processed by Stripe. Prices exclude taxes, which you are responsible for where applicable.
• We may suspend service for accounts with overdue balances after reasonable notice.

WordKey retains all rights in the service, the protocol, the SDK, and the WordKey and Word? marks. We grant businesses a limited, non-exclusive, revocable license to use the SDK and marks solely to integrate and present WordKey authentication.

The service is provided "as is" and "as available". To the fullest extent permitted by law, WordKey disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. During the waitlist and early-access period, features may change or be withdrawn.

To the fullest extent permitted by law, WordKey will not be liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, or data. Our total liability for any claim arising out of the service is limited to the greater of (a) the amounts you paid WordKey in the twelve months before the claim and (b) one hundred U.S. dollars ($100).

Business account holders will indemnify WordKey against third-party claims arising from their application, their use of the API in violation of these Terms, or their handling of end-user data.

You may stop using the service at any time; consumers may delete their word and account in the app. We may suspend or terminate access for breach of these Terms. Sections 7–13 survive termination.

These Terms are governed by the laws of the State of South Carolina, without regard to its conflict-of-laws rules. The state and federal courts located in South Carolina will have exclusive jurisdiction over any dispute not subject to informal resolution.

We may update these Terms; material changes will be reflected in the effective date above and, for business accounts, notified by email. Questions: legal@wordkey.app.
