StructFlow is a local-first browser extension for formatting code, viewing JSON, taking notes, and saving snippets. It collects nothing.

Data collection

StructFlow does not collect, transmit, sell, or share personal data. It uses no analytics, tracking pixels, remote logging, advertising identifiers, or AI services.

Local storage

StructFlow stores app data locally in your browser:

Saved library entries — raw input, formatted output, titles, tags, folder assignments, pinned state, and timestamps.
Folders and their display colors.
Formatter draft content.
Preferences: app theme, syntax theme, default language, recently used languages, and the in-page JSON viewer on/off setting.
Temporary selected text sent from the right-click menu into the side panel.

This data stays on your device unless you manually export it.

Permissions

sidePanel — shows the app in the browser's side panel.
storage — stores your preferences and temporary context-menu input.
contextMenus — adds a right-click action to open StructFlow with selected text.
Content script access on pages — detects raw JSON pages and renders the optional in-page JSON viewer (which you can turn off in Settings). The script only reads the page it is rendering.

Network use

StructFlow makes no network requests for formatting, storage, analytics, or licensing.

Exported files

When you export, StructFlow creates files locally and downloads them to your device. Exported ZIP files may contain your saved snippets, notes, titles, tags, folder names, and metadata.
