("Brain," "we," "our," or "us"), incorporated in the United States, is committed to protecting your data and information. This Cookies Policy outlines how we use cookies and similar technologies to operate our websites, documentation, applications, APIs, and related services. This Cookie Policy explains what cookies are, how we use them, and the choices you have. It should be read together with our [Privacy Policy](/legal/privacy-policy.md). {% hint style="info" %} Questions about this policy? Contact us at {% endhint %} ### What Are Cookies? Cookies are small text files placed on your device when you visit a website. They help websites remember information about your visit, such as your preferences, session status, browser type, or usage activity. We may also use similar technologies such as pixels, local storage, software development kits, tags, and analytics tools. ### How We Use Cookies Brain may use cookies and similar technologies for the following purposes: #### Essential Cookies These cookies are necessary for our websites and services to work properly. They may support security, authentication, session management, fraud prevention, load balancing, and basic site functionality. You cannot disable essential cookies through our cookie tools because the services may not function correctly without them. #### Functional Cookies These cookies help us remember user preferences, such as interface settings, documentation preferences, region, language, or other settings that improve your experience. #### Analytics Cookies These cookies help us understand how users interact with our websites, documentation, and services. For example, they may help us measure page visits, traffic sources, feature usage, error patterns, and overall performance. We use this information to improve Brain’s product experience, content, documentation, and service reliability. #### Security and Fraud Prevention Cookies We may use cookies and similar technologies to detect abuse, protect accounts, prevent unauthorized access, monitor suspicious activity, and maintain the integrity of our platform. #### Marketing and Measurement Cookies Where permitted, we may use cookies to understand the effectiveness of our marketing, improve messaging, measure campaigns, and show more relevant content. We do not use these cookies to sell your personal information. ### Third-Party Cookies Some cookies may be placed by third-party service providers that help us operate, secure, analyze, or improve our websites and services. These providers may include hosting, analytics, infrastructure, security, customer support, payment, CRM, or marketing tools. Their use of cookies is governed by their own policies. We do not control third-party cookies once they are placed by those providers, but we choose service providers that support our business, security, and compliance needs. ### Cookies and Personal Information Cookies may collect or be linked to information such as: * Device type * Browser type * IP address * Approximate location * Pages viewed * Referring URLs * Session identifiers * Usage events * Account or login status, where applicable Where cookie data identifies or can reasonably be linked to you, we treat it in accordance with our Privacy Policy. ### Your Choices You can control cookies in several ways: #### Browser Settings Most browsers allow you to block, delete, or manage cookies. Blocking certain cookies may affect how our websites or services function. #### Cookie Banner or Preferences Tool Where required, we may provide a cookie banner or preference center that allows you to accept, reject, or customize certain non-essential cookies. #### Analytics and Advertising Controls Some third-party analytics or advertising providers offer their own opt-out tools. You may also be able to manage tracking preferences through your browser, device, or platform settings. ### Do Not Track Some browsers offer “Do Not Track” signals. Because there is no consistent industry standard for responding to these signals, our websites may not respond to them in a uniform way. Where legally required, we will honor applicable privacy choices and opt-out signals. ### Data Retention Cookies may remain on your device for different periods of time. Session cookies are deleted when you close your browser. Persistent cookies remain for a set period or until you delete them. The duration depends on the cookie’s purpose and the settings of Brain or the applicable third-party provider. ### International Users Brain may operate across different jurisdictions. By using our websites or services, your cookie-related information may be processed in the United States or other locations where Brain or its service providers operate. ### Updates to This Policy We may update this Cookie Policy from time to time to reflect changes in our technology, services, legal obligations, or business practices. When we make material changes, we will update the effective date or provide additional notice where required. ### Contact For any questions about these Terms, please contact us at --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.brain.fi/legal/cookies-policy.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
