ETX Toolbox is a modular browser extension providing a unified suite of 25 independent productivity, capture,
e-commerce ad spy, and AI content utilities. This Privacy Policy outlines what information the extension stores
locally, when network requests occur, and how browser permissions are strictly utilized.
1. Core Privacy Commitment
Zero Tracking: ETX Toolbox operates without any remote user analytics, advertising trackers, or
telemetry SDKs.
Local First: All preferences, plugin states, downloaded media metadata, and tool configurations
are stored locally on your device.
No Data Selling: We do not collect, transmit, or sell personal user data to third parties.
Explicit Action Only: Third-party API communication (such as AI summarization or TikTok media
fetching) only occurs when explicitly initiated by the user.
2. Data Stored Locally on Your Device
The extension utilizes chrome.storage.local, localStorage, and IndexedDB
strictly for essential functionality:
Extension Preferences & State: Enabled/disabled plugin states, custom display order, UI
language selection (English/Vietnamese), and side panel target preferences.
E-Commerce & Ad Spy Cache: Download queue history for TikTok videos and original MP3 audio
tracks saved locally to disk.
AI Content Studio Configuration: API keys (OpenAI, Gemini, OpenRouter), selected model
profiles, and user-customized prompt presets.
Smart Capture & Session Recorder: Page screenshot annotations, region crop dimensions, and
recorded DOM event timelines (rrweb format) stored in local IndexedDB.
Developer & Utility Settings: Saved notes, custom domain CSS rules, color picker HEX
history, reading time statistics, and Pomodoro timer preferences.
3. Data Sent to Third-Party Services
ETX Toolbox performs network requests strictly to deliver requested features:
TikTok & E-Commerce Media Downloader: When saving TikTok video or audio posts without
watermarks, the extension fetches public media assets directly from official CDN servers. No user credentials,
session cookies, or personal tracking identifiers are transmitted.
AI Content Features: If you use AI Summarizer, Translator, or Copywriter features, text content
explicitly selected or submitted by you is sent directly to your configured AI provider (e.g., OpenAI, Google
Gemini, Anthropic, or OpenRouter) via secure HTTPS requests using your provided API key.
Remote Image Processing: Features like Image Converter process images locally inside your
browser using HTML5 Canvas APIs without uploading files to remote conversion servers.
4. How Browser Permissions Are Used
downloads — Save TikTok videos, audio tracks, webpage images, captured screenshots, and extracted
text files directly to your device's Downloads folder.
activeTab — Capture visible tab viewports for screenshots, sample pixel color values for Color
Picker, and inspect page DOM for media detection.
sidePanel — Render the main ETX Toolbox dashboard in Chrome's native side panel interface.
storage — Store user preferences, plugin states, color history, and custom tool rules locally.
tabs — Read current tab titles and URLs for Page Insight reading time calculation and screenshot
stitching.
scripting — Inject lightweight content scripts on open web pages to enable interactive tools like
Floating AI Text Selection and Color Picker.
bookmarks — Display bookmark folder trees and allow one-click page bookmarking.
cookies — Display active domain cookies and permit users to clear tracking cookies for privacy
control.
clipboardWrite — Copy captured screenshots, sampled colors, AI summary text, and extracted content
to your system clipboard.
contextMenus — Add right-click shortcuts for downloading images, extracting text, and generating AI
summaries from selected text.
notifications — Send desktop notifications when Pomodoro timer focus or break intervals end.
<all_urls> — Enable page-level content scripts to run across websites requested by the user.
5. Data Retention & User Control
All extension data stored in chrome.storage.local or IndexedDB remains on your device
until manually cleared or until the extension is uninstalled.
You can clear saved notes, screenshot history, color palettes, and session recordings at any time directly
within the extension options menu.
Uninstalling ETX Toolbox automatically removes all local storage associated with the extension.
