Privacy Policy for StyleCraft

Last updated: February 14, 2026

Overview

StyleCraft is a browser extension that allows users to customize the appearance of websites by applying custom CSS styles. Your privacy is important to us. This policy explains what data StyleCraft handles and how it is used.

Data Collection

StyleCraft does not collect, transmit, or share any personal data.

All data created and used by StyleCraft is stored entirely on your device using Chrome's local storage API (chrome.storage.local). No data ever leaves your browser.

Data Stored Locally

StyleCraft stores the following data locally on your device:

  • Custom CSS styles you create for websites
  • Theme preferences (UI theme selection, readability settings)
  • Installed community styles downloaded from UserStyles.world
  • Auto-backup snapshots (up to 3 rotating backups of your styles)
  • Extension settings (badge counter preference, sort/filter state)

Network Requests

StyleCraft makes network requests only in the following situations:

  • UserStyles.world search: When you search for community styles, StyleCraft sends search queries to userstyles.world to retrieve publicly available style listings. No personal data is included in these requests.
  • Style installation: When you install a community style, StyleCraft fetches the style's CSS from the UserStyles.world API.
  • Update checks: StyleCraft periodically checks UserStyles.world for updates to installed community styles.

No analytics, tracking, telemetry, or advertising services are used.

Permissions Justification

  • storage: Save your custom styles and settings locally
  • scripting: Inject your custom CSS into web pages
  • tabs: Detect the active tab's URL to apply site-specific styles
  • contextMenus: Provide right-click options to style or hide elements
  • alarms: Schedule daily automatic backups of your styles
  • host_permissions (<all_urls>): Apply user-created CSS styles to any website the user chooses to customize

Third-Party Services

StyleCraft integrates with UserStyles.world, a public community repository of user-created website styles. When you search for or install community styles, requests are made to UserStyles.world's public website and API. No account or personal information is required or transmitted.

Data Sharing

StyleCraft does not share any data with any third party. No data is sold, transferred, or used for advertising, analytics, or any purpose other than providing the extension's functionality.

Limited Use Disclosure

StyleCraft's use of information received from Google APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Changes to This Policy

If this privacy policy is updated, the changes will be reflected in this document with an updated date.
