(“Streamlit”) located at http://streamlit.io (the “Site”), the community support forum offered through the Site and the User Components (collectively, the “Support Services”). 

By using the Support Services, which may include accessing and using User Components in connection with Streamlit, you agree to be bound by these Terms and the Privacy Policy referenced in Section 1 below. If you don’t agree to be bound by these Terms and the Privacy Policy, do not use the Support Services.

2. Changes to Terms

We may update these Terms at any time, in our sole discretion. If we do so, we’ll let you know either by posting the updated Terms on the Site or through other communications. It’s important that you review the Terms whenever we update them or you use the Site. If you continue to use the Site after we have posted updated Terms, you are agreeing to be bound by the updated Terms. If you don’t agree to be bound by the updated Terms, then you may not use the Support Services anymore.

5. User Content and Usage Data

5.1. User Content

“User Content” means any text, graphics, images, software, works of authorship, and information or other materials that you provide to be made available through the Support Services, but excludes Submitted Components. For example, a screenshot of an app you made that you posted onto the Streamlit forum. Streamlit does not claim any ownership rights in any User Content and nothing in these Terms will restrict any rights that you may have to use and exploit your User Content. By making any User Content available through the Support Services you grant to us a non-exclusive, transferable, worldwide, royalty-free license, with the right to sublicense, to use, copy, modify, create derivative works based upon, distribute, publicly display, and publicly perform your User Content in connection with operating and providing the Support Services.

5.2. Your Responsibility for User Content

You are solely responsible for all your User Content. You represent and warrant that you own all your User Content or you have all rights that are necessary to grant us the license rights in your User Content under these Terms, and that neither your User Content, nor your use and provision of your User Content to be made available through the Support Services, nor any use of your User Content by Streamlit on or through the Support Services will infringe, misappropriate or violate a third party’s intellectual property rights, or rights of publicity or privacy, or result in the violation of any applicable law or regulation.

5.3. Removal of User Content

You can remove your User Content by specifically deleting it. However, in certain instances, some of your User Content (such as posts or comments you make on the community support forum) may not be completely removed and copies of your User Content may continue to exist on the Support Services. We are not responsible or liable for the removal or deletion of (or the failure to remove or delete) any of your User Content.

  • The Streamlit software (the “Software”) enables you to engage and use third-party code, components, widgets and tools (collectively, “User Components”) when using the Software. These User Components allow you to write your own JavaScript and HTML components that can be rendered in Streamlit apps, receive data from apps, and send data to Streamlit Python scripts. You may create User Components for your own use, or choose to share them with the Streamlit Community. These terms apply to User Components that have been shared within the Streamlit Community via the Support Services.

  • You acknowledge and agree that regardless of how User Components may be offered to you, Streamlit is only acting as an intermediary between you and the third party (which may include other users of the Software) offering such User Components.

Your relationship with the User Components and any terms governing your use of User Components is subject to a separate agreement between you and the provider of a User Components (“Third Party Agreements”).

  • Streamlit and the providers of each User Components reserve the right to discontinue the use or suspend the availability of any User Component, for any reason and with no obligation to provide any explanation or notice.
