Summary

PrompTrace stores captured records locally in the user's browser using IndexedDB, chrome.storage, and browser-managed Downloads. The extension does not sell user data, does not use advertising analytics, and does not transfer user data to third parties except when the user explicitly enables and configures an optional summary provider.

簡單說：PrompTrace 的資料預設保存在你的瀏覽器本機，不賣資料、不做廣告追蹤。只有在你主動啟用摘要功能並設定 API provider 時，才會把需要摘要的紀錄文字送到你設定的摘要服務。

Data handled by PrompTrace

The extension may handle the following data only to provide its core features:

  • Website content: selected text, image URLs, video URLs, previews, and saved prompt workflow assets intentionally captured by the user.
  • Web history metadata: source page URL and page title for saved records, so users can organize and trace where a record came from.
  • User settings: language, role colors, hotkey, UI preferences, summary settings, trash retention settings, and optional API key.
  • Local file metadata: filenames, download IDs, download status, and file status for media downloaded by the extension.

Where data is stored

PrompTrace stores data locally in:

  • IndexedDB for saved records, assets, categories, tags, and metadata.
  • chrome.storage for extension settings.
  • The browser Downloads folder for user-selected downloaded media, under a PrompTrace folder.

PrompTrace does not operate a backend account system or cloud sync service.

Optional summary provider

If the user enables prompt summaries and provides an API key, selected record text may be sent to the user-configured summary provider only to generate summaries. API responses are treated as data and are not executed as code.

Users can disable summaries, remove the API key, or choose a different provider in the extension settings.

What PrompTrace does not do

  • Does not sell user data.
  • Does not use saved content for advertising or analytics.
  • Does not track users across websites for behavioral advertising.
  • Does not read clipboard contents.
  • Does not inspect, manage, or modify unrelated downloads.
  • Does not use remote executable code. All extension JavaScript is bundled in the extension package.

Permissions and why they are used

  • contextMenus: adds PrompTrace actions to save selected text, images, or videos when the user chooses the menu item.
  • downloads: downloads user-selected media into a PrompTrace folder and removes extension-created files when records are permanently deleted.
  • storage: stores settings and local metadata.
  • alarms: runs local scheduled tasks, such as optional summary checks and trash retention cleanup.
  • activeTab: interacts with the active tab after a user-initiated action.
  • scripting: injects packaged PrompTrace UI and content scripts into pages where the user uses the extension.
  • clipboardWrite: writes saved prompt text to the clipboard when the user clicks copy actions.
  • Host permissions: allow PrompTrace to work on user-selected content across websites where the user chooses to use the extension.

User control and deletion

Users can edit, restore, export, or delete saved records from the local library. Records moved to Trash remain restorable until the configured retention period expires. Users may also permanently delete records immediately.

Permanent deletion removes the record, related local metadata, related assets, tags, and extension-created local file records. When possible, the extension also removes downloaded files that it created through the browser downloads API.
