# Privacy Policy for xb

Effective date: April 12, 2026

xb is a browser extension for Weibo that helps users reduce timeline noise, improve readability, and enjoy a clean reading experience.

This Privacy Policy explains what information xb processes, how that information is used, and what choices users have.

## Scope

This Privacy Policy applies to the xb browser extension and its current core features, including:

- hiding distractions such as promoted content, stickers, ads, and supertopics
- improving reading flow through page enhancements
- saving extension preferences locally in the browser

## Information xb Processes

xb processes content from pages on `weibo.com` and `www.weibo.com` only to provide the extension's user-facing features.

This may include:

- timeline and feed content needed to hide, expand, or reorganize visible page elements
- profile and status page content needed to improve layout and readability
- extension settings such as appearance preferences and feature toggles

## How Information Is Used

xb uses processed information only to provide the extension's core functionality, including:

- modifying the appearance and behavior of Weibo pages at the user's request
- hiding ads, stickers, supertopics, and other distracting elements
- storing user preferences so the extension can remember settings between sessions

xb does not use processed information for advertising, profiling, or unrelated analytics.

## Data Storage

xb stores user settings locally in the browser using the browser's extension storage (`chrome.storage`).

Core extension features are designed to process page content locally in the user's browser. xb does not sell user data.

## Network Access

xb runs only on `weibo.com` and `www.weibo.com` pages.

All page content processing happens locally in your browser. xb does not make network requests to external servers.

## Data Sharing

xb does not sell personal information or website content to third parties.

xb does not transfer processed information for purposes unrelated to the extension's core functionality.

## User Choice and Control

Users can control xb by:

- enabling or disabling extension features
- changing or removing stored preferences
- uninstalling the extension at any time

Removing the extension will stop all further local processing by xb. Users may also clear extension data through the browser's extension management tools.

## Security

xb is designed to keep its data footprint limited to what is necessary to provide the requested functionality. However, no software or storage mechanism can guarantee absolute security.

## Changes to This Privacy Policy

This Privacy Policy may be updated from time to time to reflect changes in the extension's functionality, legal requirements, or operational practices. The latest version should be published at the same public URL used in the Chrome Web Store listing.

## Contact

If you have questions about this Privacy Policy, contact the publisher through the contact method listed in the xb Chrome Web Store listing or project repository.
