Inputs and Outputs from chats, coding sessions and connected services are collected
Anthropic collects what you submit through the Services — chat, coding, agentic sessions where Claude performs multi-step tasks, connected services, and content you upload or integrate — and calls it Inputs, while generated responses and actions are Outputs. Personal data or external content included in Inputs is collected and may be reproduced in Outputs. Depending on permissions granted to Claude, some Outputs can act outside the Services, such as sending communications, modifying files or interacting with third-party services on your behalf.
Supporting quotations
You are able to interact with our Services in a variety of formats, including but not limited to chat, coding, agentic sessions (where Claude performs multi-step tasks or takes actions on your behalf), and connected services.
The content you submit to the Services through these interactions, including via third-party applications, services, and content you choose to upload, integrate or interact with using our Services, are your “Inputs”.
Inputs generate responses and actions (“Outputs”).
If you include personal data or reference external content in your Inputs, we will collect that information and it may be reproduced in your Outputs.
Depending on the permissions you grant Claude, some Outputs may result in actions with effects outside the Services, such as sending communications, modifying files, or interacting with third-party services on your behalf.
Qualifications & exceptions
Covers interactions through the Services, including third-party applications, services and content you choose to upload, integrate or interact with.
Actions outside the Services occur only depending on the permissions you grant Claude.
