Privacy:
- This extension does not collect, store, or transmit any personally identifiable information (PII).  
- All inputs, conversions, and copy actions happen locally in your browser and are not sent to any server.  
- No ads, tracking pixels, analytics SDKs, or third‑party statistics scripts are included.

Permissions:
- `contextMenus`: Adds a conversion item to the right‑click menu so that, when you select a number like “6” or “6mm”, you can trigger the extension popup with that value prefilled.  
- `clipboardWrite`: Powers the “Copy Text” and “Copy Image” buttons, allowing the extension to write the converted result into your clipboard.

Data usage:
- Numeric values you enter are used only for real‑time conversion and display; they are not persisted.  
- Text and images written to the clipboard are created only when you explicitly click the copy buttons.  
- The extension does not analyze or upload your browsing history, form data, or page content.

Single purpose statement:
This extension has a single purpose: to convert between millimeters and inches in the browser and help you copy the resulting dimensions as text or images. It does not provide any unrelated features.

Why these permissions are required:
We request only the minimum permissions needed to support this single purpose:  
- `contextMenus` lets the extension add a right‑click menu item that, when clicked, opens the extension popup with the selected number automatically prefilled.  
- `clipboardWrite` is needed so that, when you click a copy button, the current conversion result can be placed directly on your clipboard.  
The extension does not perform background tasks beyond this scope.
