The behavior makes the distinction between current model context, deferred session logs, feedback-triggered history, and desktop analytics operationally important. ## Reporting record ### Finding In Windows build 0.2.1-rc.3, turning the additional log-upload setting back on can make unaccepted session events recorded while it was off eligible for a later transfer. ### How we verified Methods: reverse engineering, testing. RuntimeWire’s inspection of the installed Windows package and comparison of selected bundled files; DeepSeek’s public session-log documentation; and seven saved local sessions containing 302 delivery-accepted markers. On October 25, 2026, RuntimeWire read the installed Windows package and compared selected bundled files with their contents, reviewed DeepSeek’s public session-log documentation, and examined seven saved local sessions and their delivery-accepted markers. The app was not launched, and no test prompts were sent. Tested versions: - Windows build 0.2.1-rc.3 ### Reproduction RuntimeWire was not able to independently reproduce the finding. No live network transfer was reproduced; the app was not launched and no test prompts were sent. [DeepSeek Harness](https://www.deepseek.com/en/harness/?ref=runtimewire), the agent product from the company founded by Liang Wenfeng, can make session activity recorded while its additional log-upload setting was off eligible for transfer after a user turns the setting back on, RuntimeWire found in an inspection of Windows build 0.2.1-rc.3.… When you purchase through links in our articles, [we may earn a small commission](https://runtimewire.com/affiliate-monetization-standards).
