DeepSeek

No documented export of the agent that can be restored on a runtime or host DeepSeek does not operate; the Privacy Policy mentions only copying or deleting chat history via settings, and portability requests go by email to privacy@deepseek.com.

• DeepSeek Privacy Policy (Your Choices, Your Rights)

Any export documented covers chat history (conversation text) only; account settings, model and behaviour configuration remain with the provider.

• DeepSeek Privacy Policy
• Third-party: Univik export guide (conflicting report of no in-app export)

The agent runs only on DeepSeek's hosted service with a registered account, and Terms 3.1 grant only a 'revocable, non-transferable, and non-exclusive right' to use it.

• DeepSeek Terms of Use §2.2, §3.1

The chat agent is served only with DeepSeek's own models; no documented way exists to select another model. Open MIT weights allow self-hosting the model, not this agent.

• Model Mechanism and Training Methods of DeepSeek
• DeepSeek API Change Log

Terms 8.2 allow DeepSeek to close accounts and delete content at its own judgement, with no post-termination export window; Terms 11.1 and 1.3 allow the service to be suspended or terminated. State lives only on the provider's servers.

• DeepSeek Terms of Use §1.3, §8.2

Agent state (chat history, settings) is readable only through DeepSeek's hosted service; no public schema or owner-held keys are documented.

• DeepSeek Privacy Policy

Two shortfalls: the base/system prompt placed in context is not shown to the owner, and provider-controlled behaviour switches such as the 'risk filtering mechanisms' of Terms 3.3 cannot be determined. The served model is determinable only through changelog announcements.

• DeepSeek Terms of Use §3.3
• DeepSeek API Change Log (2026-08-13: V4-Pro GA rolled out on APP, Web)

Retention is 'as long as necessary', including for 'legitimate business interest', with no bounded periods; device IDs, user IDs, logs and cross-device activity are collected but are not visible item by item.

• DeepSeek Privacy Policy (Automatically Collected; How Long Do We Keep)

The Privacy Policy states DeepSeek does not do targeted advertising or sell data, and no paid placement is described. This rests on a policy that can change on posting (Terms 11.1), so it is non-binding under G6. Which third-party search APIs are used is not disclosed.

• DeepSeek Privacy Policy
• DeepSeek Terms of Use §11.1

The chat history is the only record. Provider-side actions such as content deletion or account restriction under Terms 8.2 are not recorded for the owner, and nothing documents that failed recording is surfaced (G12). Searches send keywords to third parties with no documented argument-level record.

• DeepSeek Terms of Use §8.2
• DeepSeek Privacy Policy (Service Providers: search APIs)

No integrity data, signatures or verifier for the chat or action record are documented; the provider can alter or delete it without trace.

• DeepSeek Terms of Use

The documented tools (search, reasoning, file reading) give the model no evident path to alter its chat history, but no protection is documented, so it rests on architecture by convention only (G12).

• DeepSeek Terms of Use §1.2, §5.2

The hosted chat application and serving stack are closed, and Terms 3.5(3) forbid attempting to discover the source. Only model weights and inference code are MIT-licensed.

• DeepSeek Terms of Use §3.5
• Model Mechanism and Training Methods of DeepSeek (Model Open-Source)

The only identity is a DeepSeek account that the provider can restrict, close or bar from re-registration (Terms 2.2, 8.2).

• DeepSeek Terms of Use §2.2, §8.2

No documented history of changes to settings, model or behaviour per account, and no restore of a prior state.

• DeepSeek Privacy Policy

No owner-editable system prompt or custom instructions is documented by DeepSeek; a third-party guide reports there is no custom-instructions field. Base instructions are fixed provider-side.

• DeepSeek Terms of Use
• Third-party: DeleteMe DeepSeek privacy settings guide

Primary sources document no cross-session memory. Chat history persists, can be deleted but not edited. That no other memory is reused is established only by third-party sources, which cannot support a pass.

• DeepSeek Privacy Policy (Your Choices)

The tool set (search, deep thinking, file upload) is fixed; no documented way to add owner-built tools to the chat agent.

• DeepSeek Terms of Use §5.2
• DeepSeek homepage

Terms 3.3 give DeepSeek the right to apply risk filtering and content-review mechanisms; no owner control over any provider-imposed protection is documented.

• DeepSeek Terms of Use §3.3

The changelog records DeepSeek-V4-Pro GA 'rolled out on the APP, Web, and API' with no opt-in, and retired models' names silently re-routed to V4.1-Flash. Terms 1.3 allow modifications with notice only when changes 'may greatly affect your rights'.

• DeepSeek API Change Log
• DeepSeek API Docs: Your First API Call
• DeepSeek Terms of Use §1.3

Contact and spend are treated as met (G11: the agent cannot message others or pay). Two shortfalls remain: tool/data scope is on/off only (search toggle, no per-domain limits), and there is no limit on instruction sources such as injected web content.

• DeepSeek Terms of Use §4.4, §5.2

No owner-set approval gates are documented; searches and outbound keyword sharing proceed without approval once search is on.

• DeepSeek Privacy Policy (search APIs)

No primary documentation of a stop control or its guarantees; the chat UI could not be observed (HTTP 403). No scheduled or background work is documented (G11).

• chat.deepseek.com (HTTP 403 to evaluator)

Inputs and outputs are used to improve and train models unless the user turns off 'Improve the model for everyone' (opt-out), data is shared with group entities for 'foundation model training', and policy changes apply on posting without specific consent.

• DeepSeek Terms of Use §4.3, §11.1
• DeepSeek Privacy Policy (How We Use, Our Corporate Group, Updates)

The agent holds no integration credentials beyond optional Apple/Google sign-in, for which DeepSeek collects an access token. Such grants are revocable at the identity provider, but nothing in-product lists them or documents deletion of the token copy.

• DeepSeek Privacy Policy (Personal Data from Other Sources)

Account deletion exists, but Terms 2.5 reserve the right to retain data after deletion, no completion limit or confirmation is stated, and de-identified training copies are not covered.
