A Windows analysis says Kimi Work’s feedback form reaches beyond the feature or conversation a user is reporting. In a detailed investigation, RuntimeWire reports that Kimi Desktop 3.1.5 selected the five most recently updated Work conversations and attempted to upload a bounded raw-record archive for each when a user pressed Submit.
HashSparks has not independently reproduced that behavior or audited the binaries. The finding is RuntimeWire’s, supported by its published methods, component versions, file hashes and blocked-network test. It should not be enlarged into a claim about every Kimi Work release, macOS, successful server receipt or uploads that occur without an explicit feedback submission.
The distinction at the center of the story is narrower: the user chose to send feedback, but, according to RuntimeWire, the visible form did not identify the diagnostic package or records selected from five other recent conversations.
What RuntimeWire says it tested
Ryan Merket reports examining Kimi Desktop 3.1.5, release 3.1.5+c88420152, with the bundled Daimon 0.5.49 service on Windows x64. RuntimeWire says its static trace followed the feedback action from the renderer through Electron’s internal messaging, archive generation and two HTTP endpoints.
For a runtime check, Merket says he created a Windows Firewall rule blocking outbound traffic from the signed Kimi.exe, opened Kimi Work’s Plugins page and submitted harmless test feedback. The application then attempted a diagnostic upload and five raw-record uploads associated with distinct conversation IDs, according to the report. All external requests failed as intended with ERR_NETWORK_ACCESS_DENIED; Kimi’s local main-process log ended with ok: 0/5 archives uploaded in 166ms.
That test matters because it moves the finding beyond an unused code path: the production handler allegedly selected conversations and reached the upload stage after Submit was pressed. It also has a hard limit. Because the firewall blocked the requests, the test did not show successful receipt, retention, access by Moonshot staff, use of the data or any additional server-side filtering.
RuntimeWire says the shipped client sorted Work conversations by their updatedAt value, took five and asked Daimon to generate a separate archive for each. The current conversation was not passed into the selector, its report says. That is why feedback opened from a general location such as Plugins could reach across unrelated recent work.
“Raw records” does not mean an unlimited copy
The report describes bounded archives, not an unlimited byte-for-byte dump of everything connected to a session. For each selected conversation, RuntimeWire says Daimon could collect up to 100 agent record files and the last 500 JSONL records from each. Each compressed archive was capped at 8 MiB, producing a stated client-side maximum of 40 MiB across five session archives, plus a separate diagnostic package.
Kimi’s session documentation describes wire.jsonl files as agent event streams used for recovery and replay; it says they also carry request traces including tool schemas, request parameters and MCP tool listings. The documentation separately says session exports include persisted session files and diagnostic logs, warns that exported material may contain code, command output and file paths, and advises users to review it before sharing.
RuntimeWire says the feedback archive code applied size- and encoding-based sanitization: large base64-like strings could be removed, oversized values replaced by length-and-hash markers, and ordinary strings limited to 8,192 characters. It reports finding no client-side scan of retained ordinary strings for passwords, API keys, tokens, private source code, shell output or sensitive paths. HashSparks has not inspected that logic, so both the limits and the absence of content-aware filtering remain attributed findings.
The feedback form and privacy policy answer different questions
Kimi’s general feedback help tells desktop users where to submit product feedback. A separate contact page says in-product reports automatically attach “device and account context.” That is notice that some background context travels with a report. It does not enumerate diagnostic logs, raw conversation records, five sessions or how those sessions would be chosen.
The Kimi Privacy Policy is broader. It says the policy applies to Kimi applications and PC versions unless a separate product policy controls, and describes collection of conversation information, usage records, feedback information and logs. It also warns users to consider whether content supplied during feedback contains third-party personal or confidential information.
Those categories may provide policy-level notice that conversation and feedback data can be processed. They do not establish what a user sees immediately before submitting a particular report. Conversely, an interface-disclosure gap does not by itself prove that the collection falls outside the policy. This report makes no legal conclusion.
Kimi’s own developer product offers a useful comparison without setting a universal rule. The Kimi Code /feedback documentation tells users to choose among no attachment, logs only, or logs plus codebase, and describes what each option sends. Its explicit session-export warning tells users to review potentially sensitive contents. RuntimeWire says the Kimi Work form it tested offered no comparable list, preview or session selector.
The version boundary matters
Kimi says Kimi Work launched on June 3, 2026, remains in beta and changes frequently. It ships in the Work mode of the Kimi desktop client for Mac and Windows, using Kimi Code as its local-agent kernel. RuntimeWire’s reproduction covered one Windows build and one bundled Daimon version.
Nothing in the published test establishes the same behavior on macOS. Nor does it establish whether a release after 3.1.5 removed, changed or more clearly disclosed the collection. The official product page’s promise that local actions are permission-controlled concerns what the agent can do with local files; it should not be treated as a specific description of feedback attachments.
RuntimeWire says it requested comment from Moonshot AI and had received no response by publication time. Independent reproduction would strengthen the record: the signed 3.1.5 Windows installer could be matched to RuntimeWire’s hashes and tested with synthetic sessions, while the current Windows release and macOS would need separate checks. The defensible conclusion remains attributed and version-specific.
RuntimeWire has presented unusually detailed evidence that Kimi Desktop 3.1.5 on Windows attempted to bundle bounded records from five recent Work conversations after a user submitted feedback, without naming those conversations in the form. HashSparks independently checked RuntimeWire’s published reporting record and Kimi’s current public documentation, but did not reproduce or audit the product behavior itself.
