DeepSeek Privacy Policy
DeepSeek operates under a privacy policy that governs how the AI platform collects, processes, and protects user data. As of March 2026, the official privacy policy is accessible through the DeepSeek website and outlines the company's commitments to data protection and user privacy. Understanding this policy is essential for anyone using DeepSeek for personal projects, research, or production deployments, particularly when handling sensitive information through the API or web interface.
The policy addresses core concerns around personal data collection, conversation history retention, and whether user inputs contribute to model training. DeepSeek states that account registration requires basic information such as email addresses and usernames, while usage generates additional data including conversation logs, API calls, and interaction patterns. The company emphasizes transparency about data flows and provides mechanisms for users to exercise control over their information.
Like most AI platforms, DeepSeek balances service improvement with user privacy. The policy explicitly covers data retention periods, third-party sharing practices, and compliance with international regulations including GDPR and CCPA. For developers integrating DeepSeek API into applications, the policy clarifies responsibilities around end-user data and provides guidance on implementing privacy-compliant solutions. The last substantive update to the privacy policy occurred in January 2026, reflecting changes to data retention practices and expanded user control options.
Data Collection and Usage
DeepSeek collects several categories of data to operate the platform and improve service quality. Account information includes email addresses, usernames, payment details for paid tiers, and authentication credentials. Conversation data encompasses all prompts submitted to the model, generated responses, and associated metadata such as timestamps and model versions used. Usage analytics track API call volumes, feature utilization patterns, response times, and error rates. Device information collected includes IP addresses, browser types, operating systems, and device identifiers for web interface users.
This data serves multiple purposes within DeepSeek's operations. Service delivery requires conversation data to generate responses and maintain session context across multi-turn dialogues. Model improvement involves analyzing usage patterns to identify edge cases and failure modes, though the policy distinguishes between aggregate analytics and individual conversation review. Personalization uses interaction history to optimize response quality for repeat users, particularly for API clients with consistent usage patterns. Security monitoring leverages access logs and usage data to detect abuse, prevent unauthorized access, and enforce rate limits.
| Data Type | Primary Purpose | Retention Period |
|---|---|---|
| Account information | Authentication and billing | Duration of account plus 90 days |
| Conversation history | Service delivery and context | 30 days default, user-configurable |
| API usage logs | Billing and rate limiting | 12 months |
| Device and access data | Security and fraud prevention | 6 months |
| Payment records | Transaction history and tax compliance | 7 years (regulatory requirement) |
The most critical aspect for privacy-conscious users concerns model training. As of the March 2026 policy update, DeepSeek does not use conversation data from paid API accounts for training purposes by default. Free tier users may have anonymized conversation data included in training datasets unless they explicitly opt out through account settings. This distinction matters significantly for enterprise deployments handling proprietary information or personal data. The policy specifies that any training data undergoes anonymization to remove identifying information, though the effectiveness of anonymization techniques remains a subject of ongoing research in the AI field.
- Paid API accounts: Conversation data excluded from training by default, no opt-out required
- Free tier accounts: Anonymized data may contribute to training unless user opts out in settings
- Enterprise contracts: Explicit data isolation guarantees available with custom agreements
- Research partnerships: Separate consent required for any academic or collaborative data usage
Users seeking absolute assurance that their data never contributes to model training should use paid API tiers or verify their account settings immediately after registration. The opt-out mechanism for free accounts is accessible through the privacy dashboard and takes effect within 24 hours of activation. For developers building applications on DeepSeek API, the policy recommends implementing additional user consent mechanisms if end-user data will be transmitted to the platform, particularly in jurisdictions with strict data protection requirements.
Data Storage and Security
DeepSeek stores user data across geographically distributed data centers with primary infrastructure located in the United States and secondary facilities in Singapore and Germany as of early 2026. Data residency depends on the user's account region, with European users' data typically processed within EU boundaries to maintain GDPR compliance. API requests route to the nearest available data center for optimal latency, though users can specify regional preferences through API parameters for compliance-sensitive workloads. The company does not currently offer on-premises deployment options, meaning all data processing occurs on DeepSeek-controlled infrastructure.
Security measures protecting this data include encryption at rest using AES-256 for stored conversation history and account information. Data in transit uses TLS 1.3 for all API connections and web interface communications. Access controls implement role-based permissions with mandatory two-factor authentication for accounts with administrative privileges or enterprise billing access. Regular security audits occur quarterly, conducted by third-party firms specializing in cloud infrastructure assessment.
- SOC 2 Type II certification obtained in December 2025, covering security and availability controls
- GDPR compliance framework implemented with designated data protection officer for EU users
- CCPA compliance measures for California residents, including data sale prohibition
- ISO 27001 certification in progress as of March 2026, expected completion Q3 2026
- Penetration testing conducted biannually with public disclosure of critical vulnerabilities after patching
In the event of a data breach affecting user information, DeepSeek commits to notification within 72 hours of breach discovery for affected users. Notification occurs via email to registered account addresses and includes details about the scope of compromised data, potential impacts, and remediation steps. The policy specifies that regulatory authorities receive notification as required by applicable laws, with public disclosure for breaches affecting more than 1,000 accounts. As of March 2026, DeepSeek has not disclosed any significant data breaches impacting user privacy, though minor security incidents involving attempted unauthorized access have been documented in quarterly transparency reports.
User Rights and Controls
DeepSeek users possess several rights regarding their personal data, with specific provisions varying based on jurisdiction. The right to access allows users to request a complete copy of all personal data the platform holds about them, including conversation history, account details, and usage analytics. Data export arrives in JSON format within 30 days of request submission, though most users can download conversation history directly through the web interface for immediate access. The right to deletion enables users to request complete removal of their data from DeepSeek systems, with permanent deletion occurring within 90 days after a 30-day grace period for account recovery.
GDPR-specific rights for European users include data portability in machine-readable formats, the right to rectification of inaccurate information, and the right to restrict processing for specific purposes. CCPA rights for California residents encompass the right to know what personal information is collected and sold, the right to deletion, and the right to opt out of data sales. DeepSeek explicitly states it does not sell personal data to third parties, though aggregate anonymized usage statistics may be shared with research partners under specific agreements. Users can invoke these rights through the privacy dashboard or by submitting requests to the data protection contact listed in the policy.
- Conversation history deletion: Available instantly through web interface settings, removes all chat logs older than 24 hours
- Training data opt-out: Toggle available in privacy settings, processes within 24 hours for free tier accounts
- Account deletion: Requires email confirmation, initiates 30-day grace period before permanent removal
- Data export request: Submitted through privacy dashboard, delivered via secure download link within 30 days
- Marketing communications opt-out: Unsubscribe link in all promotional emails, processes immediately
To delete your DeepSeek account completely, navigate to account settings and select the privacy and security section. Click the "Delete Account" option and confirm via the email sent to your registered address. During the 30-day grace period, you can cancel deletion by logging in and selecting "Restore Account." After this period, all data undergoes permanent deletion including conversation history, API keys, and billing information except for transaction records retained for tax compliance. API access terminates immediately upon deletion request submission, not after the grace period, so ensure you've migrated any production workloads before initiating the process.
Response timeframes for data rights requests depend on complexity and verification requirements. Simple requests like conversation history export typically complete within 5 business days. Complex requests involving data rectification or access to backend analytics may require the full 30-day window allowed under GDPR. DeepSeek provides request tracking through the privacy dashboard, with status updates at each processing stage. For urgent requests related to suspected unauthorized access or data breaches, priority processing occurs within 48 hours when accompanied by appropriate documentation. Enterprise customers with custom contracts may negotiate faster response times and dedicated privacy support contacts as part of their service agreements.
