The ngrok Services are available only to individuals who are at least 18 years old and to companies that are appropriately licensed and otherwise legally permitted to conduct business. You represent and warrant that, (a) if you are an individual, you are at least 18 years old, and (b) if you are a company, that (i) you are appropriately licensed and legally permitted to conduct business and (ii) the individual accepting these terms on your behalf is authorized to do so.
ngrok may make changes to the Terms from time to time. We will provide notice at the top of this page of the latest update date, and on the dashboard of the ngrok service, if the Terms change in any substantive way. We will provide at least seven (7) days' notice before the changes take effect, during which period of time you may reject the changes by stopping all use of and access to the ngrok Services and (if you have an ngrok account) terminating your account.
This Agreement incorporates ngrok's Privacy Policy, which is currently located at https://ngrok.com/privacy ("Privacy Policy") and ngrok's Copyright Policy, which is currently located at https://ngrok.com/copyright.
Use of Services
License to ngrok Services. Subject to these Terms, ngrok grants to you a non-exclusive, non-transferable, non-sublicensable, revocable right: (a) to access and use the ngrok Services during the Term (as defined below); and (b) to download and, copy the ngrok Agent; and (c) if you have an ngrok account, distribute the ngrok Agent to third parties to whom you make available an application created by you using the ngrok Software in connection with which you, not your customer, maintain an account with ngrok. Such third parties are referred to as "Customer Licensees." Notwithstanding the foregoing, you may, subject to ngrok's prior written consent (which it may grant or withhold in its discretion), distribute the ngrok Agent to your customers who maintain their own accounts with ngrok. All rights not expressly granted by ngrok hereunder remain the sole property of ngrok.
Use of ngrok Services. You will be solely responsible for all use of the ngrok Services accessed by you (including but not limited to use by the Customer Licensees and whether or not authorized) or under your account, and you shall ensure that all such use is in accordance with this Agreement. You will be solely responsible for all acts and omissions of your representatives, consultants, contractors, subcontractors, agents or Customer Licensees who are authorized by ngrok or you to use the ngrok Services. You will take all reasonable precautions to prevent unauthorized access to or use of the ngrok Services and will promptly notify ngrok in writing immediately of any unauthorized access to or use of the ngrok Services of which you become aware.
Customer Data. You will ensure that ngrok is entitled to use any data, information or material provided, submitted, or otherwise made available by you or on behalf of you to ngrok in the course of using or accessing the ngrok Services ("Customer Data") as needed to provide you with the functionality of the ngrok Services. You understand and agree that ngrok's Privacy Policy, shall apply to all Customer Data. ngrok may collect, retain, use, and disclose data and other information about you and your users, including but not limited to Customer Data, subject to the terms of ngrok's Privacy Policy. You also agree to the terms of ngrok's Data Processing Agreement located at https://ngrok.com/dpa (the "DPA"), which is hereby incorporated into this Agreement. You shall ensure that all users have provided all necessary consents and permissions for you to make Customer Data available to ngrok under these Terms, including for use, retention, and disclosure in accordance with ngrok's Privacy Policy. If you are an EU data subject (as defined under the EU General Data Protection Regulation ("GDPR")), you shall ensure that Customer Data does not include sensitive personal data (as defined under the GDPR). Please note that, for the version of the ngrok Services for which ngrok does not charge a fee, ngrok may include the IP address of the ngrok Agent in the hostnames ngrok assigns to you or in HTTP headers included in responses to requests passing through the Proxy Service, thus making that IP address available in connection with any HTTP request to the Proxy Service. Accordingly, and without limiting your other obligations under this Agreement, to the extent the GDPR applies, you acknowledge and agree that (a) such use of the data subject's IP address is part of your processing of personal data as a controller under the GDPR, and (b) you will promptly inform the data subject(s) who may be identified by such IP address(es) that the IP address(es) will be so available. You acknowledge and agree that ngrok may use Customer Data to improve your use of the ngrok Services and may use aggregated and anonymized Customer Data to improve the ngrok Services generally. You also acknowledge and agree that ngrok may access, preserve and disclose your account information and other Customer Data if required to do so by any applicable law or if ngrok in good faith believes that such access, preservation or disclosure is reasonably necessary to: (i) comply with any applicable legal process; (ii) enforce this Agreement; (iii) respond to claims that any Customer Data violates the rights of third parties; (iv) respond to your requests for customer service; or (v) protect the rights, property or personal safety of ngrok, its customers and/or users and/or the public. In no event shall ngrok or its designees have any liability or obligation to you in connection with exercising any rights set forth in this Section.
