This Cookie Policy explains what cookies are, how we use them on deep-seek.chat, and how you can manage your preferences. It is aligned with our Privacy Policy and complies with applicable laws in the EU/UK (GDPR/ePrivacy), US (including CCPA/CPRA), and Canada (PIPEDA).
What Are Cookies?
Cookies are small text files stored on your device when you visit a website. They help websites function, improve performance, remember preferences, and — where allowed — support analytics and advertising. Cookies can be session (deleted when you close the browser) or persistent (expire after a set time), and can be first-party (set by us) or third-party (set by another domain).
How We Use Cookies
We use cookies to run our site securely and reliably. Some cookies are strictly necessary and are always active. Other cookies (e.g., analytics and advertising) are used only where permitted by law and/or with your consent (e.g., EU/UK). You can change your choices at any time via Manage Cookie Preferences.
- Strictly Necessary: Required for core functions (e.g., security, load balancing, session continuity, remembering your cookie choices). These do not require consent in EU/UK.
- Functionality/Preferences: Remember options you choose (e.g., language). We only set them when you request such features. Some may require consent where not essential.
- Analytics (Google Analytics): Help us understand aggregated site usage to improve the Service. Set only with consent in EU/UK and disabled where you opt out. We do not build individual marketing profiles from analytics data.
- Advertising (Google AdSense): Deliver, measure, and cap ads; may personalize ads where you allow it. Requires consent in EU/UK. In California/US states with privacy laws, you may opt out of “sale/sharing” for cross-context ads.
Third-Party Tools Involved
- Cloudflare (security/performance, e.g., DDoS protection, WAF). May set security cookies to distinguish bots from humans.
- Google Analytics (aggregate usage metrics; GA is configured per your consent/region).
- Google AdSense (ad delivery/measurement; personalization depends on your consent and regional law).
- Fireworks.ai API (AI inference). Does not set cookies in your browser for normal chat usage; processes prompts/outputs to generate responses.
Details on these processors are in our Privacy Policy.

Manage Cookie Preferences
You can control optional cookies at any time using our preference tool: Manage Cookie Preferences. (If your browser blocked the banner/tool, check your content blockers or use the link in our footer.)
Your Choices (Browsers & Platforms)
- Browser Controls: Most browsers let you block/delete cookies. Blocking all cookies may break essential site functions.
- Google Ads Personalization: Control at adssettings.google.com.
- Google Analytics Opt-Out: If GA is enabled in your region, you can use Google’s opt-out add-on.
- Global Privacy Control (GPC): Where legally required (e.g., California), we treat a valid GPC signal as an opt-out of sale/sharing for advertising purposes.
Regional Notes
- EU/UK: No non-essential cookies are set without your prior consent. You can withdraw consent at any time in the preference tool.
- US (CCPA/CPRA): You may opt out of “sale/sharing” of personal information for cross-context ads. We honor GPC as an opt-out signal where applicable.
- Canada (PIPEDA): We obtain meaningful consent for non-essential cookies and provide clear options to withdraw.
Consistency with Our Privacy Policy
This Cookie Policy reflects our current practice: we may use analytics and advertising cookies depending on your consent and local law. If we change vendors, purposes, or cookie categories, we will update this page and — where required — re-obtain consent.
Updates
We may update this policy as our site or legal requirements evolve. Significant changes (e.g., introducing new cookie categories) will be highlighted in our banner/tool and on this page, and consent will be refreshed where required.
