Worked on the ggml-org/llama.cpp repository to deliver a user data management feature for the web UI, focusing on privacy and data lifecycle control. Built the Delete All Conversations functionality within the Import/Export tab, implementing a confirmation dialog, trash icon, and clear destructive styling to guide user actions. Leveraged Svelte and TypeScript to manage state and navigation, ensuring users are redirected to a new chat state after deletion via conversationsStore.deleteAll(). Enhanced the UI/UX for clarity and compliance, updating build artifacts to reflect these changes. No critical bugs were reported during this period, emphasizing a focus on feature delivery and maintainability.
