Claude offers solid end-user controls through privacy settings, Incognito chats, exports, and account deletion paths.

Desktop use can feel local, but prompts and attachments are still cloud service inputs with training, safety, and feedback exceptions.

Claude Desktop benefits from Anthropic's account privacy settings, Incognito chats, exports, and deletion controls.

Mobile prompts often mix personal context, voice-style notes, and attachments, which raises the cost of leaving training or feedback paths enabled.

Claude Mobile keeps the main Claude account controls available across devices.
