1. Introduction

Please read the terms of this entire document (“Terms”) carefully because it explains your rights and responsibilities when you visit our website and/or use Postful to submit your own content, retrieve generated content or create and publish social media posts (collectively, “Services”). The Services are owned, licensed, and operated by Mozilla Corporation (referred to herein as “we,” “us,” “our,” or “Mozilla”). By accessing the Services, you agree to be bound by these Terms.

2. The Services

A. Using the Services.

The Services enable you to easily create and publish social media posts using Your Content (defined below) and/or using third-party artificial intelligence (AI) based models (“AI models”), such as OpenAI, to submit Inputs (defined below) and generate Outputs (defined below), and image websites. You understand that Outputs generated by AI models may contain inaccuracies or offensive content which we do not control and do not represent our views.

Our Services may connect you with links, apps or add-ons that are provided by other parties and are subject to separate terms. In some instances, we may partner with third parties and may earn a commission from your interactions with their links, apps or add-ons, including, but not limited to, clicking on links to third-party websites, clicking on advertising links, or purchasing an item. We do not directly share or sell your personal information to these affiliates and your use of their services is subject to their respective terms of service and privacy policy.

You agree that you will not use the Services to violate any laws in the jurisdiction where you are based. You are prohibited from using the Services if you are barred under any Office of Foreign Assets Control Specially Designated Nationals List or face any other similar prohibition in any other applicable jurisdiction.

3. Content  & Ownership

A. Your Content

You may contribute text, images, video (including embedding from third party sites), audio, contact information, and other information or content as well as submit prompts and links to your information or social media accounts to AI Models(“Inputs”) for the purposes of generating social media posts (“Outputs”)  (collectively “Your Content”) when using the Services. You retain ownership of Your Content. For all Your Content you submit and your use of the Services, you agree to the following:

i. You represent and warrant that Your Content will comply with these Terms, Mozilla’s Acceptable Use Policy, and any additional terms that may govern the Services.

  • Outputs generated by AI Models through your use of the Services may be the same or similar to outputs generated for our other users or users of those AI Models generally. 

Solely as between you and us, we do not claim any ownership rights in or to Outputs generated through your use of the Services.

 C. Third-Party Image License
