Every conversation is saved automatically in the sidebar.
Renaming: Click the conversation title in the sidebar or at the top of the chat. Clear names make it easier to find things later.
Deleting: Open the conversation, click the menu (three dots) at the top, and select Delete. Permanently removes all messages and attachments from that session. Cannot be undone.
Conversation contents are encrypted at rest, only accessible to you, and never used for training. If you delete your account, all conversations are permanently deleted.
