Kimi Privacy Policy and Data Security Guide

Learn how your information is protected, managed, and kept secure with Kimi's transparent privacy standards.

Kimi Privacy Policy

When you start using Kimi, you're trusting the platform with your conversations, questions, and data. That's a big deal, and the Kimi privacy policy lays out exactly how that information gets handled. The official policy on Moonshot AI's website is the authoritative source, but let's break down what it actually means for you in plain language. The last update to Kimi's privacy policy was rolled out in early 2026, reflecting new compliance standards and user control features that make data management more transparent than ever.

Here's the core promise: Kimi collects data to make the service work better, keeps it secure, and gives you control over what happens to your information. No hidden surprises, no vague language about "improving experiences" without specifics. You'll see exactly what data they collect, why they need it, how long they keep it, and what buttons you can push to take it back or delete it entirely. If you're comparing AI assistants and privacy matters to you, understanding Kimi's approach helps you make an informed choice without wading through legal jargon.

Data Collection and Usage

Kimi collects several types of data when you use the platform, and each category serves a specific purpose. Your account information—email, username, profile details—helps identify you and secure your account. Conversation data is the big one: every question you ask, every response Kimi generates, every follow-up in a thread is logged. Usage analytics track how you interact with features, which tools you use most, and where you spend time in the interface. Device information rounds it out—your browser type, operating system, IP address, and general location data help optimize performance and catch security threats.

How does Kimi use all this? Service improvement means analyzing patterns to fix bugs and refine features. Model training is the critical question everyone asks: yes, conversation data can be used to train and improve Kimi's underlying AI models, but you can opt out. Personalization tailors responses based on your history and preferences, making the assistant more useful over time. Security monitoring uses behavioral data to detect unusual activity and prevent unauthorized access. Everything Kimi collects ties back to making the service faster, smarter, and safer.

Data Type	Primary Purpose	Retention Period
Account Information	User authentication and support	Duration of account plus 90 days
Conversation Data	Service delivery and model training	30 days default, or until user deletion
Usage Analytics	Feature optimization and performance	Aggregated data retained indefinitely
Device Information	Security monitoring and compatibility	90 days from last activity

The opt-out for model training is straightforward: head to your account settings, find the data preferences section, and toggle off "Use my conversations to improve Kimi." Once disabled, your chats stay private and won't contribute to training future versions. This gives you full control without sacrificing the core functionality of the assistant. Retention periods are clear—conversation data is wiped after 30 days unless you manually save it, and account data disappears 90 days after you close your account.

Account data includes email, username, password hash, and profile settings.
Conversation logs capture full message threads with timestamps and metadata.
Usage analytics track feature engagement, session duration, and error rates.
Device information logs browser type, OS version, IP address, and timezone.
Opting out of training prevents your data from contributing to model improvements.

Data Storage and Security

Kimi stores user data in certified data centers located primarily in China and Singapore, with regional routing to ensure compliance with local data protection laws. If you're in Europe, your data stays within GDPR-compliant infrastructure. Users in North America connect to servers optimized for low latency while meeting US data residency requirements. This geographic distribution isn't just about speed—it's about keeping your information within legal frameworks that protect your rights.

Security measures are layered and serious. All data is encrypted in transit using TLS 1.3 and at rest using AES-256 encryption. Access controls limit who inside Moonshot AI can view user data, with strict audit logs tracking every interaction. Kimi maintains SOC 2 Type II certification and complies with GDPR, CCPA, and China's Personal Information Protection Law. If a data breach occurs, Kimi's policy requires notification within 72 hours to affected users and relevant regulatory authorities. That's not just good practice—it's a legal obligation in most jurisdictions where Kimi operates.

Primary data centers located in China and Singapore with regional routing.
TLS 1.3 encryption for data in transit, AES-256 for data at rest.
Role-based access controls with audit logging for internal access.
SOC 2 Type II certified with GDPR and CCPA compliance.
72-hour breach notification policy for affected users and regulators.

Compliance certifications aren't just badges—they represent third-party audits that verify Kimi's security practices meet industry standards. SOC 2 Type II means an independent auditor examined Kimi's controls over a six-month period and confirmed they work as advertised. GDPR compliance ensures European users get rights like data portability and the right to be forgotten. CCPA coverage gives California residents similar protections. If data security matters to you, these certifications provide tangible proof that Kimi takes protection seriously.

User Rights and Controls

You own your data, and Kimi's policy reflects that with clear rights and easy-to-use controls. You can access everything Kimi has on you by requesting a data export from your account settings—it arrives as a downloadable JSON file within 48 hours. Deletion rights let you wipe specific conversations, clear your entire chat history, or permanently delete your account and all associated data. Export capabilities mean you can take your data to another platform if you decide to switch. Opting out of training, as mentioned earlier, prevents your conversations from improving future models.

GDPR users get additional rights: the right to rectification if your data is incorrect, the right to restrict processing for specific purposes, and the right to object to automated decision-making. CCPA users in California can request disclosure of what data Kimi sells (spoiler: none, according to the policy) and opt out of any hypothetical future sales. These aren't just theoretical rights—Kimi provides specific mechanisms to exercise them, and response timeframes are written into the policy.

Request a full data export from account settings, delivered within 48 hours.
Delete individual conversations by clicking the trash icon in chat history.
Clear all chat history from the privacy section in account settings.
Close your account and request full data deletion with a 30-day processing window.
Opt out of model training by toggling the setting in data preferences.

To delete your account completely, navigate to account settings, scroll to the bottom, and click "Delete Account." Kimi will prompt you to confirm by entering your password and checking a box acknowledging that all data will be permanently removed. The process takes up to 30 days as deletion propagates through backup systems, but your account becomes inaccessible immediately. If you change your mind, you have a 7-day grace period to cancel the deletion and restore your account. After that window closes, everything disappears for good—no backups, no recovery, no exceptions.

Response timeframes matter because vague promises don't protect you. Kimi commits to acknowledging data requests within 5 business days and fulfilling them within 30 days. If a request is complex or requires additional verification, they'll notify you of the delay and provide a revised timeline. This transparency removes guesswork and holds the platform accountable. If you're exercising GDPR or CCPA rights and don't get a response within the stated period, the policy includes escalation procedures to contact a data protection officer directly.
