LICENSE AND SCOPE OF USE
Upon the purchase of our self-hosted, cloud or hybrid self-hosted software, the Client is granted a non-exclusive, non-transferable, single-user license to use the software solely within their organization and for the specific user or department identified at the time of purchase. The license may not be shared with or transferred to other users or departments within the Client’s organization without our prior written consent. Each purchase entitles the Client to one license, which is restricted to use by the designated user or department. Any usage beyond this scope requires the purchase of additional licenses.
LangWatch provides its software in the following deployment models:
Cloud: The software is hosted and managed by LangWatch, with LangWatch responsible for availability and performance, making reasonable efforts to minimize downtime.
Self-Hosted: The Client hosts and manages the full software on their own infrastructure, which may include on-premise servers or cloud environments such as AWS, Azure, or Google Cloud. The Client is solely responsible for updates, security, and maintenance.
Hybrid Self-Hosted: The Client utilizes LangWatch Cloud for AI solution management, monitoring, and optimization, while all client data (input and output of LLMs) remains on the Client’s infrastructure. LangWatch has no access to the content of LLM processing performed locally by the Client. The Client retains full responsibility for the management, security, and regulatory compliance of all data processed through LangWatch Hybrid AI.
In the Hybrid Self-Hosted model, LangWatch ensures the availability and performance of its cloud services but does not process or access any confidential data. The Client is responsible for maintaining a secure and stable environment for AI processing requests.
The Client acknowledges that for Self-Hosted and Hybrid Self-Hosted deployments, they bear full responsibility for infrastructure maintenance, data security, and regulatory compliance related to LLM input and output processing.
