English
Threadmark – AI Conversation Navigator is a local-first browser extension for navigating, searching, bookmarking, and reviewing ChatGPT and Gemini conversations.
Data the extension reads
The extension reads the visible conversation page to identify user questions, answer previews, message identifiers, and positions required for navigation. When the user opens question details or runs a full scan, the extension may also process rendered answer HTML.
Data stored locally
The extension stores the following data in the current browser profile:
- Question directory and navigation metadata.
- Bookmarks, notes, and tags created by the user.
- Sanitized answer HTML used by the local detail panel.
- Local control values used to prevent stale writes between tabs.
Directory metadata is stored with chrome.storage.local.
Cached answer HTML is stored in IndexedDB.
Remote transmission
Threadmark does not upload conversation content, directories, bookmarks, notes, or cached answers. It does not use advertising, analytics, tracking SDKs, or remote code.
The extension contains user-initiated links to this privacy policy and the public support page. Opening a link sends a normal web request to the selected site, but Threadmark does not append conversation content or locally stored data to those links.
Data management
The extension settings allow the user to:
- View approximate storage usage.
- Delete data for the current conversation.
- Delete all Threadmark data.
- Export the current conversation or all stored conversations.
- Import and merge a valid Threadmark JSON export, including compatible exports created before the product was renamed.
Deleting extension data does not delete the original conversation from ChatGPT or Gemini. Export files may contain sensitive conversation content and must be stored securely.
Retention
Bookmarks, notes, and directory metadata remain until the user deletes them. Cached answer HTML may be removed automatically when local cache limits are reached. Automatic cache cleanup does not delete bookmarks or notes.
