THESE TERMS OF SERVICE (the "Agreement") GOVERN CUSTOMER'S RECEIPT, ACCESS TO, AND USE OF AIRFRAME SOFTWARE (AS DEFINED BELOW) PROVIDED BY CORE STACK LLC ("Core Stack"). IN ACCEPTING THIS AGREEMENT BY (A) PURCHASING AIRFRAME THROUGH AN ONLINE ORDERING PROCESS THAT REFERENCES THIS AGREEMENT, (B) DOWNLOADING OR INSTALLING AIRFRAME THROUGH A PROCESS THAT REFERENCES THIS AGREEMENT, OR (C) CLICKING A BOX INDICATING ACCEPTANCE, CUSTOMER AGREES TO BE BOUND BY ITS TERMS.

THE INDIVIDUAL ACCEPTING THIS AGREEMENT DOES SO ON BEHALF OF A COMPANY OR OTHER LEGAL ENTITY ("Customer"); SUCH INDIVIDUAL REPRESENTS AND WARRANTS THAT THEY HAVE THE AUTHORITY TO BIND SUCH ENTITY TO THIS AGREEMENT. IF THE INDIVIDUAL ACCEPTING THIS AGREEMENT DOES NOT HAVE SUCH AUTHORITY, OR THE APPLICABLE ENTITY DOES NOT AGREE WITH THESE TERMS AND CONDITIONS, SUCH INDIVIDUAL MUST NOT ACCEPT THIS AGREEMENT AND MAY NOT INSTALL OR USE AIRFRAME. CAPITALIZED TERMS HAVE THE DEFINITIONS SET FORTH HEREIN. THE PARTIES AGREE AS FOLLOWS:

1. AirFrame Software

1.1. Software Description.

Core Stack is the owner and provider of AirFrame, an installable software application for product teams ("AirFrame" or the "Software"). AirFrame is designed to be installed and operated on Customer's own computer systems under a subscription licensing model. Anything Customer (including Users) creates, stores, or otherwise generates through AirFrame is considered "Customer Data." Customer is solely responsible for all Customer Data created through use of AirFrame. AirFrame may also include templates, help documents, and other materials that can assist Customer in using AirFrame ("Core Stack Content"). Upon installation, Customer will receive the executable files necessary to operate AirFrame on their systems.

1.2. Customer's License.

Subject to the terms of this Agreement, Customer may purchase a subscription license to install and use AirFrame as specified in one or more ordering screens agreed to by the parties through Core Stack's website that reference this Agreement and describe the business terms related to Customer's license ("Order(s)"). All licenses are subscription-based for the period described on the applicable Order ("Subscription Period"). Installation and use of AirFrame is permitted only by individuals authorized by Customer and for Customer's own internal business purposes and not for the benefit of any third party ("Users").

1.3. Core Stack's Ownership.

Core Stack owns AirFrame, Core Stack Content, Documentation, and anything else provided by Core Stack to Customer (collectively the "Core Stack Materials"). Core Stack retains all right, title and interest (including, without limitation, all patent, copyright, trademarks, trade secret and other intellectual property rights) in and to the Core Stack Materials, all related and underlying technology and any updates, enhancements, upgrades, modifications, patches, workarounds, and fixes thereto and all derivative works of or modifications to any of the foregoing. There are no implied licenses under this Agreement and any rights not expressly granted to Customer in this Agreement are expressly reserved by Core Stack.

1.4. Installation and System Requirements.

Customer is responsible for ensuring their computer systems meet the minimum system requirements for AirFrame as specified in the Documentation. Customer is also responsible for proper installation, configuration, and maintenance of AirFrame on their systems. AirFrame requires internet connectivity for license validation, updates, and certain features. Core Stack may provide installation support and updates, but Customer remains responsible for the ongoing operation of AirFrame on their systems.

1.5. Subscription License Operation.

(a) Active Subscription Required: Continued use of the Software requires an active, paid subscription managed through Core Stack's payment processor.
(b) License Validation: The Software may periodically connect to Core Stack servers to validate subscription status and deliver updates.
(c) Internet Connectivity: The Software requires internet connectivity for license validation and may not function without an active internet connection.
(d) Subscription Lapse: If subscription terminates or expires, Software functionality will be disabled until subscription is renewed, but Customer retains full access to Customer Data stored locally on Customer's systems.
(e) Auto-Renewal and Cancellation: Subscriptions automatically renew for successive periods of the same duration unless Customer cancels their subscription before the renewal date. Cancellation prevents future renewals but does not terminate the current subscription period.

2. Restrictions

2.1. Customer's Responsibilities.

Customer is responsible for all activity related to the Software installation and use on their systems. Customer will ensure that its Users are aware of and bound by obligations and/or restrictions stated in this Agreement and Customer will be responsible for breach of any such obligation and/or restriction by a User.

3. Third-Party Applications

AirFrame may integrate with or work together with third party products, services or applications that are not owned or controlled by Core Stack (e.g., databases, operating systems) ("Third-Party Applications") and Customer, at its sole option, may choose to use such Third-Party Applications. Customer acknowledges and agrees that this Agreement does not apply to Customer's use of such Third-Party Applications and Customer may be required by the providers of such Third-Party Applications to enter into separate agreements for Customer's use. Core Stack provides no warranties for such Third-Party Applications, except for integrations specifically warranted in the Documentation. Customer will look solely to the providers of the Third-Party Applications for any warranty related issues or other claims. Customer's use of Third-Party Applications is at Customer's own risk. Core Stack will have no liability or other obligation of any kind arising out of or related to any third-party applications.

4. Payment Obligations

4.2. Subscription Billing.

Core Stack, through its third-party payment processor Lemon Squeezy ("Payment Processor") will charge Customer for the Fees via credit card or other payment methods accepted by the Payment Processor, pursuant to the payment information provided by Customer.

Core Stack is not responsible for any error by, or other acts or omissions of, the Payment Processor.

(a) Cancellation Rights: Customer may cancel their subscription at any time through their account dashboard or by contacting Core Stack support. Cancellation prevents automatic renewal but does not terminate the current subscription period.

However, Core Stack may, in its sole discretion, provide refunds in the following circumstances: (i) material Software defects that prevent core functionality, or (ii) as required by applicable law.
(c) Failed Payments: If payment fails, Core Stack may immediately suspend or terminate Software functionality until payment issues are resolved.

4.4. Auto-Renewal Disclosure. AUTOMATIC RENEWAL: Your subscription will automatically renew for successive periods of the same duration unless you cancel before the renewal date. You will be charged the then-current subscription rate. You may cancel your subscription at any time to prevent future renewals.
