Temporary Project Mapping

Developers sketching workflows or structuring features for a quick sprint use the board to categorize deliverables without cluttering their team's official project boards.

How It Works

Local Storage State Persistence Mechanism: The local Kanban board runs entirely on client-side state hooks synchronized with the browser's Web Storage API (`localStorage`): 1. State Serialization: When a card is added, modified, or dragged, the React application updates the boards state array. 2. JSON Encoding: The updated state is encoded into a JSON string: `const data = JSON.stringify(kanbanColumnsState);` 3. Local Write: The JSON string is committed directly to the user's local sandbox: `localStorage.setItem('convertwithmi_kanban', data);` 4. Hydration: On page load, the component retrieves and parses the key: `const saved = JSON.parse(localStorage.getItem('convertwithmi_kanban'));` This ensures that your project boards remain active across refreshes and browser restarts, operating offline with zero database uploads.

Frequently Asked Questions

Where is my Kanban board data stored?▼

Your board data is stored entirely in your local web browser's `localStorage` cache. No data is ever transmitted to ConvertWithMi servers or any third-party database, making the board private.

Can I access my board from another device?▼

Because `localStorage` is completely sandboxed to the specific browser and device you are currently using, you cannot sync it dynamically with other devices. To transfer your data, you can use the Export/Import features to move the JSON backup.

What happens if I clear my browser cookies?▼

Clearing your browser's cache and site data (specifically "offline website data" or local storage) will delete the stored JSON board state. It is recommended to download a JSON backup of your board before performing system cleanups.

Is there a limit to how many tasks I can add?▼

Browser `localStorage` typically permits up to 5MB of text data per domain. A standard task card uses only a few hundred bytes, meaning you can comfortably store thousands of tasks without hitting browser storage limitations.
