9393By default, chats, Cowork tasks, and Code sessions stay on the device until the user deletes them. To delete them after a period without activity, set [`chatSessionRetentionDays`](/docs/third-party/claude-desktop/configuration#chatsessionretentiondays), [`coworkSessionRetentionDays`](/docs/third-party/claude-desktop/configuration#coworksessionretentiondays), or [`codeSessionRetentionDays`](/docs/third-party/claude-desktop/configuration#codesessionretentiondays) to a number of days from 1 to 3650. Each key covers one kind of session, and a kind you leave unset is kept until the user deletes it. Idle time counts from the session's last activity, and pinned sessions are not exempt.

95With [Unified Claude](/docs/third-party/claude-desktop/unified-claude) on, a conversation started from the home screen on a device that can run Cowork is a Cowork session. `coworkSessionRetentionDays` covers it along with users' other Cowork tasks, and `chatSessionRetentionDays` still covers Chat conversations. If you use `chatSessionRetentionDays`, keep it and set `coworkSessionRetentionDays` as well.

9597The app deletes whole sessions in the background. A chat or Cowork task is deleted with its attached files and outputs, and a Code session with its conversation. Projects, memory, and the files in a Code session's working folder stay, and Code sessions on an SSH host are not affected. A session that is running or open on screen is skipped until a later pass. To suspend all automatic deletion for some users, for example under a legal hold, set [`sessionRetentionHold`](/docs/third-party/claude-desktop/configuration#sessionretentionhold) to `true` for them. While the hold is on, nothing is deleted, and a device that gets its configuration from a server and cannot reach that server also deletes nothing. These keys require Claude Desktop 1.52386.0 or later.
