DeepSeek Data Residency: Where Is Your Data Processed and Stored?

Updated: August 25, 2026

Direct answer: For DeepSeek’s official consumer-facing services covered by its Privacy Policy, DeepSeek says it directly collects, processes, and stores personal data in the People’s Republic of China. This does not prove that every DeepSeek API integration, third-party endpoint, or self-hosted deployment uses the same data location.

For the official DeepSeek API, public documentation confirms server-side model processing and disk-based context caching, but it does not publish one universal regional-residency, zero-retention, or no-training commitment for every customer. API customers should verify processing location, retention, logging, caching, and contractual safeguards for their specific account and use case.

TL;D

• DeepSeek’s Privacy Policy states that personal data for covered services is directly collected, processed, and stored in the People’s Republic of China.
• The policy expressly excludes end-user personal data collected through downstream Open Platform applications.
• The official consumer web/app service, official API, third-party endpoints, and self-hosted deployments must be assessed separately.
• DeepSeek’s API documentation states that Context Caching on Disk is enabled by default and that unused cache data is usually cleared within a few hours to a few days.
• The cache-clearing statement is not a universal zero-retention or full API deletion guarantee.
• Self-hosting can provide stronger location control only if prompts, outputs, logs, backups, monitoring, and network egress remain within the controlled environment.
• Organizations should verify any claimed EU, US, Canadian, or regional residency commitment in current technical documentation or a signed contract.

How this page fits our privacy guides: This article focuses specifically on DeepSeek data residency, processing location, cross-border transfer risk, and the difference between hosted, API, third-party, and self-hosted deployments. For broader data collection details, GDPR analysis, workplace rules, and “what not to paste” guidance, use the dedicated guides linked below.

What Does “DeepSeek Data Residency” Mean?

Data residency means the country or region where data is stored or processed. In AI systems, this includes prompts, uploaded files, generated outputs, conversation history, API logs, cache data, telemetry, support records, and backups.

Data processing location is broader than storage. Data may be transmitted to a model endpoint, processed in memory, cached, logged for safety or debugging, used for analytics, or retained for account and service operations. DeepSeek’s Terms of Use describe its services as including websites, applications, SDKs, APIs, and other generative AI services, so “DeepSeek data residency” should be assessed across each product channel, not just the chat interface.

Data sovereignty refers to the legal and regulatory control that may apply because data is stored or processed in a particular jurisdiction. For compliance teams, the practical question is not only “Where is DeepSeek data stored?” but also “Which laws, government access rules, vendor obligations, and transfer mechanisms apply?”

Cross-border data transfer means personal data moves from one jurisdiction to another. Under the GDPR, transfers from the EEA to a third country require either an adequacy decision, appropriate safeguards, or another lawful transfer basis. Article 46 of the GDPR requires appropriate safeguards and enforceable rights when there is no adequacy decision.

Where Does DeepSeek Process and Store Data?

As of August 25, 2026, the most important source is DeepSeek’s Privacy Policy, last updated February 10, 2026. The policy says it applies to personal data processed in connection with DeepSeek apps, websites, software, and related services that link to or reference the policy. It also identifies Hangzhou DeepSeek Artificial Intelligence Co., Ltd. as the data controller for those services.

The key data residency statement appears under “Where We Store Your Personal Data.” DeepSeek states that personal data may be stored on a server outside the user’s country and that, to provide the services, it directly collects, processes, and stores personal data in the People’s Republic of China.

That wording is important. Companies should not describe the consumer-facing DeepSeek services covered by the current Privacy Policy as region-neutral or EU-resident unless separate verified documentation applies. The policy points to PRC processing and storage for personal data handled by those covered services; it does not establish the region for every API account or downstream application.

There is also an important downstream-app caveat. DeepSeek’s Privacy Policy says the processing rules for personal data collected from end users of downstream systems or applications built using DeepSeek’s open platform are not covered by that Privacy Policy; the developer operating the application is responsible for disclosing its own processing policy.

What Data Can DeepSeek Collect?

DeepSeek’s Privacy Policy groups personal data into three categories: data users provide, automatically collected data, and data from other sources.

Data category	Examples	Why it matters for data residency
Account data	Date of birth where applicable, username, email address, phone number, password	Can identify the user and may be retained while the account exists
User input	Text input, voice input, prompts, uploaded files, photos, feedback, chat history	This is the highest-risk category for business users because it may contain personal data, confidential documents, source code, or trade secrets
Contact data	Identity or age proof, contact details, feedback, inquiries	May be processed in support and compliance workflows
Device and network data	Device model, operating system, IP address, device identifiers, system language, crash reports, performance logs	Useful for security and diagnostics, but still relevant to privacy analysis
Log data	Features used and actions taken	May reveal usage patterns and business workflows
Location data	Approximate location based on IP address	Can trigger privacy review even if precise geolocation is not collected
Payment/order data	Payment order and transaction data for paid open platform services	Relevant to API and enterprise billing records

DeepSeek also says its services are not designed or intended to process sensitive personal data and tells users not to provide sensitive personal data such as health, biometric, children’s, precise geolocation, or criminal-related data.

Is DeepSeek Data Stored in China?

For DeepSeek’s official consumer-facing services covered by the Privacy Policy, yes: the policy states that DeepSeek directly collects, processes, and stores personal data in the People’s Republic of China.

For the official API, the public documents reviewed do not provide a complete regional-residency map or a universal zero-retention commitment. For third-party-hosted or self-hosted models, data location depends on the provider, cloud region, application architecture, logs, cache, backups, and monitoring systems.

However, there are three edge cases businesses should understand.

First, third-party apps using DeepSeek or the Open Platform may have their own data flows. DeepSeek says downstream systems built by developers are not covered by the same Privacy Policy, and the developer operating the downstream application is the controller responsible for its own disclosures.

Second, API integrations may involve additional technical behavior. DeepSeek’s Open Platform terms say developers can integrate DeepSeek model capabilities into downstream systems for internal organizational use or end users, and that model processing turns inputs into outputs. The same terms also make developers responsible for their downstream systems, applications, and end-user obligations.

Third, self-hosted deployments are different. DeepSeek says it publicly releases model weights, parameters, and inference tool code under a permissive MIT License, allowing users to download and deploy them. If your organization runs a DeepSeek model in its own cloud region, private VPC, or on-prem environment, the data residency question shifts from DeepSeek’s hosted service to your own infrastructure design.

DeepSeek API Data Residency: What Developers Should Know

DeepSeek API data residency requires a stricter review than casual chat use because API prompts and outputs can include production records, customer data, source code, tickets, financial analysis, contracts, or internal strategy.

DeepSeek’s API reference points developers to the Open Platform Terms of Service, and the Open Platform terms say the API service processes input to produce output.

DeepSeek’s API documentation also describes Context Caching on Disk. The current guide says the disk-based context caching technology is enabled by default for all users and that each user request triggers construction of a hard disk cache. It also states that once cache is no longer used, it is usually cleared within a few hours to a few days.

For developers, this means the API should be reviewed for at least five issues before production use: processing region, retention, cache behavior, logging, and training/optimization terms. DeepSeek’s Privacy Policy says users may have the right to opt out of using personal data for training or optimizing technologies, but API customers should verify how that right or setting applies to their specific account, contract, and integration.

Developer checklist:

• Do not send API keys, passwords, private certificates, or production secrets.
• Avoid customer PII unless legal, security, and data protection teams approve the use case.
• Confirm whether a DPA, SCCs, or equivalent transfer terms are available.
• Review logging, retention, and disk-cache behavior.
• Use redaction, tokenization, or pseudonymization before sending sensitive inputs.
• Consider self-hosted, VPC-hosted, or region-controlled alternatives for regulated workloads.
• Follow DeepSeek’s Open Platform warning not to expose API keys in browser or client-side code.

Files API Storage Is Separate from Context Caching

DeepSeek’s Files API creates a stored image object that can later be referenced by file_id with the Vision model. It currently accepts JPEG, PNG, GIF, and WebP images; it is not a general PDF, DOCX, or document-storage service.

A developer may configure an uploaded image to expire between one hour and 30 days. If no expiration is supplied, the current Files API documentation says the file is kept permanently. A separate API operation is available to delete it.

This is distinct from Context Caching on Disk, where DeepSeek documents automatic disk caching of request prefixes and says unused cache data is usually cleared within a few hours to a few days. Neither statement supplies a complete regional-residency map for API data, logs, stored images, account records, or downstream application data.

For residency-sensitive deployments, set the shortest justified file expiry, delete images when they are no longer required, avoid uploading personal data where it is unnecessary, and verify the processing region and contractual safeguards for the exact account.

DeepSeek Self-Hosted Data Residency

DeepSeek self-hosted data residency is fundamentally different from using DeepSeek’s official hosted app or API.

DeepSeek publishes downloadable weights, code, or deployment resources for several models, but the exact licence and available artifacts vary by model and repository. Organizations should verify the model card, repository, checkpoint, base model, and licence for the exact model they plan to deploy. The existence of downloadable weights does not by itself establish that every DeepSeek model or third-party derivative has the same licence.

For self-hosted deployments, always verify the license of the exact model variant you deploy. DeepSeek’s public materials describe open model releases, but repository and model-license details can differ by model. For example, DeepSeek-R1 is MIT licensed, while DeepSeek-V3’s GitHub repository lists the code under MIT and the model under a separate model license with commercial use supported.

Self-hosting gives the organization more control over where prompts, outputs, logs, caches, embeddings, and backups live. But it does not automatically solve privacy. A self-hosted model can still leak data through poor access control, excessive logging, insecure monitoring tools, exposed endpoints, misconfigured cloud storage, or third-party observability platforms.

Use case	Where data may be processed	Data residency control	Best for	Key risk
DeepSeek official web/chat app	DeepSeek’s official service environment, with personal data processed and stored in the PRC according to the Privacy Policy	Low	Public or low-risk use	Users may paste confidential or personal data
DeepSeek mobile app	DeepSeek’s official app/service environment	Low	Consumer-style general use	Device, network, prompt, and chat data may be collected
DeepSeek official API	DeepSeek Open Platform infrastructure; no universal regional-residency map is published in the public API documentation reviewed	Not established by public documentation; verify the account and contract	Controlled integrations after a documented data-flow and vendor review	Inputs, Outputs, disk cache, stored Vision images, service logs, and downstream logs require separate retention and residency review
Third-party hosted DeepSeek model	The third-party provider’s cloud, region, and contract	Varies	Teams needing managed hosting outside DeepSeek’s own service	Provider claims must be verified
Self-hosted/on-prem DeepSeek model	Your own cloud, VPC, data center, or private infrastructure	High, if engineered correctly	Regulated, confidential, or data residency-sensitive workloads	Operational burden and security misconfiguration

DeepSeek, China, and Data Sovereignty

China-based processing matters because data sovereignty is not only a technical hosting question. It affects vendor risk management, regulatory review, public-sector procurement, incident response, employee AI policy, and international transfer analysis.

The Berlin Commissioner for Data Protection stated in June 2025 that DeepSeek transfers personal data collected from users to Chinese data processors and stores it on servers in China. The same press release said the EU has not issued an adequacy decision for China and alleged a violation of GDPR Article 46(1) by the DeepSeek service.

This does not mean every organization must ban every DeepSeek-related technology. It means the review should be specific. Official hosted DeepSeek, a third-party DeepSeek endpoint, and an on-prem DeepSeek model are different risk profiles.

GDPR and DeepSeek Cross-Border Data Transfer

This section is not legal advice.

For EU/EEA personal data, the central issue is whether using the consumer-facing DeepSeek services covered by the current Privacy Policy creates an international transfer to China and, if so, whether the organization has a lawful transfer basis and appropriate safeguards. Official API and downstream deployments require their own fact-specific transfer assessment.

The European Commission’s adequacy page explains that an adequacy decision allows personal data to flow from the EU, Norway, Liechtenstein, and Iceland to a third country without further safeguards. The Commission’s current list of recognized jurisdictions includes countries and frameworks such as Japan, the Republic of Korea, the UK, and the EU-US Data Privacy Framework for participating US organizations; China is not on that list.

In the absence of an adequacy decision, the EDPB says organizations may transfer personal data where appropriate safeguards are provided and individuals can exercise rights and effective remedies. The EDPB lists Article 46 transfer tools such as SCCs, BCRs, codes of conduct, certification mechanisms, and ad hoc contractual clauses.

For a business, this usually means the privacy, legal, and DPO teams should ask:

• Is personal data being sent to DeepSeek?
• Is the data transferred from the EEA, UK, or Switzerland to China?
• Are SCCs, a DPA, or other transfer terms available?
• Has a transfer impact assessment been completed?
• Are supplementary measures possible, such as encryption, redaction, pseudonymization, or strict access controls?
• Is the use case necessary, proportionate, and aligned with company policy?

Italy’s data protection authority, the Garante, announced on January 30, 2025 that it ordered an urgent limitation on the processing of Italian users’ data by the companies providing the DeepSeek chatbot service and opened an investigation after finding the companies’ response insufficient.

Should Businesses Use DeepSeek for Sensitive Data?

For low-risk use, DeepSeek may be acceptable where employees use it only for public information, generic brainstorming, non-sensitive drafting, or learning tasks that do not involve personal data, confidential business information, source code secrets, credentials, regulated data, or customer records.

For high-risk use, businesses should be cautious. Do not send customer PII, employee data, health records, financial records, legal documents, non-public contracts, credentials, private source code, vulnerability details, board materials, M&A plans, confidential strategy, or export-controlled information into a consumer-facing DeepSeek service or the official API unless the organization has completed a formal legal and security review for that exact channel.

A practical policy is better than a vague warning. Companies should create an AI acceptable use policy that defines approved tools, prohibited data categories, approved API use cases, review workflows, logging requirements, and enforcement.

Business Checklist Before Using DeepSeek

Use this checklist before approving DeepSeek for teams, developers, or enterprise workflows.

1. Identify the exact DeepSeek channel: web app, mobile app, official API, third-party hosted model, or self-hosted model.
2. Classify the data: public, internal, confidential, personal data, sensitive personal data, regulated data, or secrets.
3. Confirm processing and storage location using official documentation or contract terms.
4. Review DeepSeek’s Privacy Policy, Terms of Use, and Open Platform terms.
5. Check retention, chat history, API caching, logging, and training/optimization settings.
6. Identify whether the workflow uses inline images, external image URLs, or stored Files API objects.
7. Set an explicit Files API expiration instead of relying on permanent storage, and delete stored images when their documented purpose ends.
8. Include application logs, backups, monitoring, and stored file_id records in the residency map.
9. Do not infer API or Files API residency from the consumer Privacy Policy.
10. Assess GDPR, UK GDPR, Swiss FADP, sector rules, public-sector rules, and internal data residency requirements.
11. Verify whether a DPA, SCCs, transfer impact assessment, or equivalent safeguard is available.
12. Evaluate self-hosting or VPC-controlled deployment for sensitive workloads.
13. Apply DLP, redaction, pseudonymization, secret scanning, and endpoint monitoring.
14. Train employees not to paste sensitive data into unapproved AI tools.
15. Monitor usage through CASB, proxy, browser controls, or endpoint controls where appropriate.
16. Document the risk assessment and revisit it when DeepSeek changes its policies or API behavior.

DeepSeek Data Residency FAQ

Where does DeepSeek process data?

For services covered by DeepSeek’s Privacy Policy, the policy states that personal data is directly collected, processed, and stored in the People’s Republic of China. The processing location for downstream API applications, third-party endpoints, and self-hosted deployments must be assessed separately.

Where is DeepSeek data stored?

DeepSeek says personal data may be stored on a server outside the user’s country and that it directly collects, processes, and stores personal data in the PRC for service delivery.

Is DeepSeek data stored in China?

For the consumer-facing services covered by DeepSeek’s current Privacy Policy, DeepSeek states that personal data is directly collected, processed, and stored in the People’s Republic of China. That statement should not be automatically extended to every API account, downstream application, third-party provider, or self-hosted deployment.

Does DeepSeek store prompts?

For services covered by its Privacy Policy, DeepSeek says User Input may include prompts, files, photos, feedback, voice input, and chat history. For the API, official documentation also describes disk-based context caching. Public documentation does not provide one fixed retention period covering every API log, Input, Output, account record, and downstream application.

For stored Vision images, the Files API uses a separate lifecycle: the developer may set an expiry of one hour to 30 days, or omit expiry and keep the image permanently until it is explicitly deleted. The public Files API documentation does not publish a complete geographic storage map.

Does DeepSeek use data for training?

DeepSeek describes model- and technology-improvement processing for services covered by its Privacy Policy and Terms. The “Improve the model for everyone” setting should not be presented as a universal API no-training commitment. API customers should verify the applicable account settings and contract.

What is DeepSeek API data residency?

DeepSeek API data residency concerns where API Inputs, Outputs, cache entries, service logs, account records, and related metadata are processed or stored. DeepSeek’s public API documentation confirms disk caching but does not publish a universal customer-selectable regional-residency or zero-retention option. Any such commitment should be verified in current documentation or a signed agreement.

Is DeepSeek GDPR compliant?

There is no simple public yes/no answer for every use case. GDPR compliance depends on the data, user location, controller/processor roles, lawful basis, transparency, transfer mechanism, safeguards, and contract terms. The Berlin Commissioner alleged that DeepSeek’s service violated GDPR Article 46(1) for transfers to China.

Does DeepSeek support EU data residency?

Based on the public official documents reviewed for this article, DeepSeek’s official Privacy Policy points to PRC processing and storage for personal data, and the official API docs reviewed do not present a public EU-hosted data residency option. Organizations should verify any region-specific commitment directly in signed vendor documentation.

What is the DeepSeek cross-border data transfer risk?

The main risk is that EU/EEA personal data may be transferred to China without an adequacy decision, requiring an Article 46 transfer tool and assessment of whether enforceable rights and effective remedies are available.

Is self-hosted DeepSeek better for data residency?

Usually, yes, if implemented correctly. Self-hosting can keep data in a chosen cloud region, VPC, or on-prem environment, but the organization must still secure logs, backups, monitoring tools, user access, and model endpoints.

Can businesses use DeepSeek with confidential data?

Businesses should not use a consumer-facing DeepSeek service or the official API for confidential or regulated data unless legal, security, and privacy teams approve the exact channel and required contractual safeguards are in place.

What should companies do before approving DeepSeek?

Companies should classify the data, identify the exact DeepSeek deployment, verify processing location, review policies and API terms, assess GDPR transfer requirements, evaluate self-hosting, and document the risk decision.

Conclusion

Organizations with strict data-residency, GDPR, data-sovereignty, confidentiality, or regulated-data obligations should treat DeepSeek’s official consumer services as involving processing in China based on the current Privacy Policy. They should assess the official API separately because the public documents do not provide one universal residency or retention commitment for every API customer or downstream application.

The safest enterprise approach is to separate use cases. Public brainstorming and low-risk research may be handled under a controlled acceptable use policy. Sensitive business data, customer PII, employee records, source code secrets, legal documents, health data, financial records, and regulated workloads should require formal approval, stronger safeguards, or a self-hosted or region-controlled deployment.

Self-hosted DeepSeek models may offer the best path for data residency control, but they still require serious governance. Data residency is not just where the model runs. It is also where prompts, outputs, logs, caches, backups, monitoring data, and support records go.
