Terms of Service

Last updated: July 27, 2026

These Terms of Service (the “Terms”) constitute a binding agreement between you and Knock AI (an unincorporated project) (“Knock AI,” “we,” or “us”) governing your access to and use of tryknockai.com and the related services (the “Service”). By registering for an account or otherwise using the Service, you agree to be bound by these Terms. If you are using the Service on behalf of an entity, you represent that you are authorized to bind that entity to these Terms.

1. Description of the Service

The Service identifies contacts responsive to criteria supplied by you, generates draft correspondence addressed to such contacts, and, following your review and express approval of each draft, transmits the approved messages from your own Gmail account. You are the sender of each message transmitted through the Service.

Where you elect to enable follow-up messages for a campaign, the Service checks, by means of the Gmail authorization described in our Privacy Policy, whether each recipient has replied, and prepares a follow-up draft only for those who have not. Follow-up messages are subject to the same requirement of your review and express approval before transmission.

2. Registration and Accounts

You must be at least eighteen (18) years of age to use the Service. You are responsible for maintaining the confidentiality of your account credentials and for all activity occurring under your account. You agree to provide accurate registration information and to keep such information current.

3. Your Obligations as Sender

You acknowledge that messages transmitted through the Service are sent under your name and from your mailbox, that you are the sender of such messages for all legal purposes, and that you bear sole responsibility for their content and for compliance with all laws applicable to you, including without limitation the CAN-SPAM Act, Canada’s Anti-Spam Legislation, the General Data Protection Regulation and applicable ePrivacy rules, and any policies imposed by your employer or institution. You agree to do each of the following:

  • Review each draft prior to approval and accept responsibility for its content.
  • Honor any request to cease contact promptly and permanently.
  • Include a valid postal address and a functioning opt-out mechanism in any message the primary purpose of which is commercial. We provide configuration settings for each, and you are responsible for determining whether such inclusion is required.
  • Comply with the Acceptable Use Policy, which is incorporated into these Terms by reference.

You represent and warrant that you have a lawful basis for contacting each individual you contact through the Service. Nothing contained in these Terms or elsewhere on the Service constitutes legal advice.

4. Generated Content

Draft messages are produced by a large language model and may contain inaccurate, incomplete, or otherwise unsuitable content. No message is transmitted without your express approval. As between you and us, you retain ownership of the messages you approve and remain responsible for their content.

5. Third-Party Services

The Service depends upon Google, Stripe, and the additional providers identified in our Privacy Policy. Your use of Gmail through the Service remains subject to Google’s applicable terms, including its sending limits and its right to suspend accounts. We have no ability to restore a mailbox suspended by Google and disclaim all liability in respect of any such suspension.

6. Fees and Payment

Fees for paid plans are billed in advance through Stripe and renew automatically for successive periods until cancelled. You may cancel at any time through the Billing page, and cancellation takes effect at the end of the then-current billing period. Except where applicable law requires otherwise, all fees are non-refundable.

Certain functions of the Service consume credits, which may be included with a plan, granted to a new account, or earned through any referral programme we may offer. Credits have no cash value, are not refundable or transferable, may not be exchanged for money, and confer no property right. Referral rewards are granted only in respect of genuine sign-ups by distinct individuals and are subject to our review before being applied. We may withhold, revoke, or reverse credits obtained through duplicate accounts, automated sign-ups, misrepresentation, or any other circumvention of these Terms, and may discontinue or amend any referral programme prospectively.

7. Acceptable Use; Suspension and Termination

We may suspend or terminate your account immediately and without refund where we reasonably determine that the account has been used to transmit unsolicited bulk email, to harass, to deceive, or otherwise in violation of the Acceptable Use Policy. Misuse of the Service adversely affects the deliverability of all Users, and we reserve the right to enforce this Section at our sole discretion.

8. Intellectual Property

We retain all right, title, and interest in and to the Service, including the underlying software, the website, and all associated trademarks. You retain all right, title, and interest in and to the content you supply, including campaign information, attachments, and approved messages. You grant us a limited, non-exclusive, royalty-free license to host, store, and process such content solely as necessary to provide the Service to you.

9. Disclaimer of Warranties

THE SERVICE IS PROVIDED ON AN “AS IS” AND “AS AVAILABLE” BASIS, WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW. WE MAKE NO WARRANTY THAT CONTACT INFORMATION IS ACCURATE OR COMPLETE, THAT ANY MESSAGE WILL BE DELIVERED, OR THAT ANY RECIPIENT WILL RESPOND.

10. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, NEITHER PARTY SHALL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL. OUR AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS PAID BY YOU TO US DURING THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM AND (B) ONE HUNDRED UNITED STATES DOLLARS (US$100). NOTHING IN THESE TERMS LIMITS ANY LIABILITY THAT CANNOT LAWFULLY BE LIMITED.

11. Indemnification

You agree to indemnify, defend, and hold harmless Knock AI (an unincorporated project) and its officers, directors, employees, and agents from and against any claims, damages, liabilities, costs, and expenses (including reasonable attorneys’ fees) arising out of or relating to the messages you transmit, the content you supply, or your breach of these Terms.

12. Modification and Termination

We may modify these Terms from time to time. Where a modification is material, we will provide notice by email or through the Service prior to the effective date, and your continued use of the Service following such date constitutes acceptance of the modified Terms. You may discontinue use of the Service and delete your account at any time through the Settings page.

13. Governing Law and Venue

These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict-of-laws principles. The state and federal courts located in the State of Delaware shall have exclusive jurisdiction over any dispute arising out of or relating to these Terms.
