Medium Code Enhancer · Last updated May 2026

No data collection

Medium Code Enhancer does not collect, transmit, or share any personal data. The extension has no servers, no analytics, and makes no network requests beyond loading the pages you visit normally.

Local processing only

All syntax highlighting and DOM enhancement happens entirely inside your browser. No article content, code snippets, or page data ever leaves your device.

Storage

chrome.storage.sync is used exclusively to store your UI preferences — theme (auto/light/dark), line numbers on/off, and enabled/disabled state. These three values are synced across your own Chrome profile via Google's standard extension sync mechanism. No article content is ever stored.

Bundled libraries

Highlight.js is bundled directly with the extension package. It is not loaded from a CDN at runtime, so no third-party requests are made.

Permissions

The extension requests the minimum permissions required:

• activeTab — read and modify the current Medium tab to enhance code blocks.
• storage — persist the three UI preferences listed above.
• clipboardWrite — copy raw code to the clipboard when you click the copy button.
