Does Kimi Store Your Prompts? Privacy and Data FAQs

Yes—Kimi, the AI assistant operated by Moonshot AI, may store prompts and other information you submit to provide and improve its services, subject to the service, settings, and applicable privacy terms. Do not assume that a prompt is immediately erased or treated as confidential: check the privacy notice for the exact product you use and avoid entering sensitive information you would not want processed or retained.

Who runs Kimi, and why data handling varies

Kimi is an AI assistant associated with Moonshot AI, a company based in China. People may access Kimi through different surfaces, such as a website, mobile app, or another service that integrates its models. These routes can have different account arrangements and privacy terms. A third-party app, for example, may collect information under its own policy as well as pass prompts to a model provider.

That is why there is no reliable one-size-fits-all answer such as “all Kimi prompts are kept for a fixed number of days.” Retention and use can depend on the product, account type, settings, region, and the current policy. Read the privacy notice linked from the specific app or website you use; a policy for an API or business product may not describe the consumer chatbot.

Privacy notices also distinguish among information types. A service may process the text you type, files or images you upload, conversation history, account details, device or usage information, and technical logs. The fact that data is processed to answer a prompt does not, by itself, establish how long it is retained or whether it is used for model improvement.

What happens when you send a prompt

When you submit a message, the service needs to receive and process it to generate a response. Depending on the product, the prompt may be associated with your account or conversation history, and related information may be collected to operate, maintain, secure, or support the service. If you upload a document or image, its contents can also be part of the information you have submitted.

Processing is not the same thing as permanent storage, but it is also not proof of immediate deletion. Providers may retain some information for operational, safety, troubleshooting, or legal reasons. The provider’s notice should explain the purposes and retention rules it discloses; if it does not give a clear period for a particular category, do not infer one.

It is useful to separate four questions that are often blurred together:

• Does the service receive the prompt? Yes, it must process the prompt to answer it.
• Is it saved in chat history? This can depend on the product and account controls.
• Is it used to improve models? Check the applicable policy and settings; do not assume the answer is the same across products.
• Is it shared or disclosed? Review the notice for service providers, operational purposes, and any other described disclosures.

Can Moonshot AI use prompts to improve its models?

Whether prompts may be used for model training or service improvement is a policy question, not something that can be answered safely from the fact that a chatbot generated a response. Terms can change, and rules may differ between consumer accounts, paid offerings, business services, and API access. Consult the current privacy notice and product terms that apply to your account, including any data-use controls shown in the product.

Also distinguish model training from other forms of improvement. A provider may describe quality review, debugging, abuse prevention, or product analytics separately. Turning off a training option, if one is offered, may not disable all processing needed to operate the service or meet other stated purposes. Likewise, deleting a chat from the screen may not mean that every associated copy or operational record is immediately removed.

If the policy or setting is unclear, treat prompts as potentially reviewable and retained according to the provider’s terms. For confidential work, use an organization-approved service with clear contractual protections rather than relying on an assumption about a consumer chatbot.

Practical steps to reduce exposure

You can limit what you disclose while still using an assistant. Before submitting a prompt, consider whether the service needs the identifying or confidential details at all. Replace them with placeholders and provide only the context needed to get a useful answer.

• Remove names, addresses, phone numbers, account identifiers, passwords, access tokens, and private keys.
• Do not upload confidential business files, private messages, financial records, or documents containing personal information unless you have approval and understand the applicable terms.
• Check account privacy controls and chat-history options, then read what each control actually changes.
• Use the available account or privacy process to request access or deletion if the provider offers one; keep in mind that deletion may be subject to stated exceptions.
• Review the terms again when switching from a website to an app, API, or third-party integration.

For example, instead of pasting a customer complaint containing a real name and order number, replace both with “[customer]” and “[order number].” The assistant can often help draft a response without those identifiers. This is data minimization: share only what the task requires.

Common privacy misunderstandings

“If I delete the conversation, it must be gone everywhere.” A delete control may remove a chat from your visible history, but the policy determines whether backups, logs, or records retained for other purposes are also affected and when. Look for the service’s explanation of deletion and retention rather than assuming the two are identical.

“The assistant is private because I am the only person who sees the chat.” Visibility in your account is different from how the provider processes information. A prompt can be private from other users while still being handled by the service under its terms.

“A public privacy policy guarantees the same settings for every user.” Policies describe broad practices, while controls and terms can differ by product, account, location, or organizational agreement. Check the exact service and account configuration in use.

“An AI response is confidential by default.” Do not treat chatbot input as protected professional communication or as a secure document vault unless the specific service and agreement clearly establish appropriate protections.

How to check the terms that apply to you

Use the privacy or legal links inside the Kimi product you actually use. Confirm the publisher and service name, the date or version of the notice, and whether it covers the consumer app, website, API, or an organization’s account. Search within the notice for terms such as “content,” “conversations,” “retention,” “training,” “improve,” “delete,” and “service providers.”

Then inspect the account’s privacy settings and any data controls. If you are using Kimi through another company’s product, read that company’s policy too: it may control account data and may have its own rules for prompts. If you need a definitive answer about a specific category of data or deletion request, contact the service through its published support or privacy channel and ask about that exact product and account type.

Frequently Asked Questions

Does Kimi save every prompt?
The service processes prompts to respond, but whether each prompt is saved, for how long, and in what form depends on the product and its current terms. Check the relevant notice rather than assuming either permanent storage or immediate deletion.

Does Kimi use my conversations to train models?
That depends on the applicable product policy and any available data-use settings. Verify the current terms for your account; do not assume a setting for one Kimi product applies to another.

Can I delete my Kimi chat history?
Look for history or deletion controls in the app or website you use. A control may remove conversations from your visible account without promising immediate removal of every operational record; consult the deletion explanation.

Is it safe to paste work or personal information into Kimi?
Only do so if the information is appropriate for that service under your organization’s rules and the terms you have reviewed. Avoid passwords, secrets, personal identifiers, and confidential material unless you have a clear, approved reason.

Does using Kimi through another app change privacy?
It can. The app or platform may have its own privacy policy and may handle account information or submitted content separately, so check both its terms and the terms of the model service where available.
