Bookmark Icon Customizer

Privacy Policy

Last updated: 2026-04-18

Bookmark Icon Customizer is designed with privacy as a first principle. This policy explains exactly what the extension does — and does not — do with your data.

What we store

The extension stores your custom icon mappings locally in your browser via chrome.storage.local. Each mapping pairs a bookmark URL with an icon (an emoji, an MDI glyph, or an image you uploaded).

This data never leaves your browser. It is not synced to any server we operate.

What we do not collect

Network requests

The extension only makes network requests in two explicit cases, both driven by URLs you configure:

  1. Bookmarks you click. When you activate a customized bookmark, your browser navigates to the original URL (for normal bookmarks) or executes your bookmarklet code (for javascript: bookmarks) — exactly as it would without the extension.
  2. Webhooks you tick. If you check the "This is a webhook" option on a bookmark, the extension fires a fetch to that URL when the bookmark is clicked. The request is sent only to the webhook URL you configured, and only when you click the bookmark.

No other network requests are made.

Permissions

Uninstalling

Removing the extension deletes all locally stored mappings. Your bookmarks are restored to ordinary URLs (customized javascript: bookmarks self-heal back to their original source on next extension load).
