1.1.2 No Work-for-Hire / Joint Development

Nothing in these Terms creates a work-for-hire relationship, joint development, partnership, or agency relationship. Customer has no ownership interest in any improvements, enhancements, or derivatives of the Services, regardless of Customer involvement, feedback, or funding.

1.2 Scope of Agreement

Certain components of the Services, such as client libraries, SDKs, and developer tools ("Client Software"), may be made available under separate open-source license terms (e.g., MIT, Apache 2.0). To the extent the terms of such open-source licenses explicitly conflict with these Terms regarding the use or modification of the Client Software code itself, the open-source license terms shall control.

Where the UK GDPR applies, the UK Addendum to the EU SCCs is incorporated. The Annexes may be completed by reference to the Services, Documentation, Sub-processor Policy, and Security measures described in the Security and Availability Disclaimer, and are deemed updated as those materials change.

Customer Data may be accessed, stored, or otherwise processed by authorised Sub-processors or Related Service Providers located in jurisdictions outside the Customer's own, including New Zealand. Where such processing constitutes an international transfer under applicable data protection law, such transfer is governed by the Standard Contractual Clauses incorporated under this DPA and any applicable addenda.

7.4.2 Optional Regional Processing Selection

MailSlurp may offer Customer the ability to select a geographic region for certain processing activities ("Regional Selection"). Where Regional Selection is available:
