Overview

Bookmark Garden is a local-first Chrome extension. It stores your X/Twitter bookmarks on your own device and does not transmit your personal data to any server, third party, or external service.

What data is stored

Bookmark Garden stores the following data locally on your device using your browser's IndexedDB storage:

• Post content: tweet text, author name, author handle, and profile image URLs
• Media: image and video URLs attached to bookmarked posts
• Link metadata: URL, title, and thumbnail of any linked article
• Your organisation: collections you create and notes you write
• Timestamps: when each post was bookmarked and when it was indexed

This data is stored exclusively on your device. It is never uploaded, synced, or shared with any server.

What permissions are used and why

storage — stores a single value (the last indexed post ID) to enable resumable indexing. Nothing else.

tabs — used to locate your X/Twitter bookmarks tab before indexing begins, and to open the Bookmark Garden gallery.

scripting — injects the indexing script into your X/Twitter bookmarks tab. Required because X is a single-page application.

Access to x.com and twitter.com — required to read your bookmarks page and inject the indexing script. Both domains are included because X serves some content from legacy twitter.com URLs.

The one external request

When displaying article cards, Bookmark Garden loads favicons via Google's public favicon service (google.com/s2/favicons). This is a standard browser image request that sends only the domain name of a saved link (for example, techcrunch.com) to Google's servers. No tweet content, no account information, no handles, and no personal data are included in this request. If the request fails, the favicon is simply hidden — no functionality is affected.
