Privacy Policy for Clipper Hub

English / 中文版

Last Updated: December 23, 2025

This Privacy Policy describes how Clipper Hub ("the Extension", "we", "us", or "our") handles information when you use our browser extension.

Summary

Clipper Hub processes all data locally on your device. We do not collect, store, or transmit any personal information to our servers. The Extension only sends data to third-party platforms (Telegram, Discord, Notion) that YOU explicitly configure and authorize.


1. Information We Access

To provide our core functionality, the Extension may access the following data:

1.1 Web Page Content

  • Selected text: Text you explicitly select on web pages for clipping
  • Page title: The title of the current web page
  • Page URL: The URL of the current web page

1.2 User Configuration

  • Platform API tokens (Telegram Bot Token, Discord Webhook URL, Notion Integration Token)
  • Database IDs and other platform-specific settings
  • Language preferences

2. How We Use Information

2.1 Core Functionality

All accessed information is used exclusively for:

  • Sending your selected content to platforms you have configured (Telegram, Discord, Notion)
  • Displaying page information in the editing interface before submission

2.2 Local Processing Only

  • All data processing occurs locally on your device
  • Content is only transmitted when you actively click "Send" or use the context menu
  • Data is sent directly from your browser to your configured platforms (Telegram API, Discord Webhook, Notion API)

3. Data Storage

3.1 Local Storage Only

All configuration data is stored locally using the browser's built-in storage APIs:

  • browser.storage.local - For user preferences and platform configurations
  • browser.storage.sync - For syncing settings across your devices (via your browser account, not our servers)

3.2 What We Store Locally

  • Platform enable/disable status
  • API tokens and credentials you provide
  • Language preferences

3.3 What We Do NOT Store

  • Browsing history
  • Web page content
  • Selected text (only processed in memory, not persisted)
  • Analytics or tracking data

4. Data Sharing

4.1 Third-Party Platforms

When you use the Extension to clip content, data is sent directly to:

  • Telegram (api.telegram.org) - if you have configured Telegram
  • Discord (discord.com/api/webhooks) - if you have configured Discord
  • Notion (api.notion.com) - if you have configured Notion

These transmissions occur:

  • Only when you explicitly initiate a send action
  • Directly from your browser to the platform's API
  • Using credentials YOU provide

4.2 No Other Data Sharing

  • We do NOT operate any backend servers
  • We do NOT collect analytics or usage data
  • We do NOT share any data with advertisers or data brokers
  • We do NOT use any third-party tracking services

5. Data Security

  • All API communications use HTTPS encryption

  • No data is transmitted to any servers controlled by us

6. Your Rights and Controls

You have full control over your data:

6.1 Access and Modify

6.2 Delete
