1. Introduction

Sheet Viewer ("we", "our", or "the extension") is a browser extension designed to help users preview Markdown, LaTeX, JSON, and images within online spreadsheets (Lark Sheet, Google Sheets, Tencent Docs). We respect your privacy and are committed to protecting it.

2. Data Collection and Usage

We do not collect, store, or transmit any of your personal data to our servers.

The extension operates entirely locally within your browser (Client-Side).

• Website Content: The extension accesses the text content of the cells you select or copy in the supported spreadsheet websites. This data is strictly used for real-time rendering and formatting within the extension's side panel.
• Clipboard Data: If you enable the "Auto-read Clipboard" feature, the extension reads your clipboard content solely to render it in the side panel.

All processing happens instantaneously on your device. No data leaves your browser.

3. Third-Party Services

The extension does not use any third-party analytics or tracking services.

4. Permissions

The extension requests the following permissions for its core functionality:

• activeTab: To access the current page content for rendering.
• clipboardRead: To read copied cell content for rendering (optional, user-enabled).
• sidePanel: To display the rendered content.
• host_permissions: To allow the extension to run on specific domains (feishu.cn, larksuite.com, google.com, qq.com).
