# CPRA logic CPRA operates primarily on an opt-out model, contrary to the GDPR (opt-in model), that is to say CPRA allows businesses to collect and process personal data until consumers explicitly request them to stop (opt-out), whereas GDPR requires businesses to obtain explicit consent from consumers before collecting and processing their personal data (opt-in). \ The signal Didomi provides about an opt-out/refusal means that you cannot share/sell the data of the user with third-party partners (vendors). For CPRA, you should not share personal information when the user refuses. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.didomi.io/consent-management-platform-cmp/frameworks-regulations/united-states-us/california-cpra/cpra-logic.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
