Content restrictions
The preview restricts content that is unnecessary for static reading, including scripts, automatic behavior, forms, iframes, and unapproved external resource loading.
When content is restricted, the Extension shows the number and reasons for the restrictions. Where possible, the corresponding location can be reviewed in the read-only Source view.
The original file in Google Drive is not modified.
Images and external resources
- Inline SVG and Base64-embedded images can be enabled or disabled in settings.
- Google Fonts are loaded from fixed Google hosts only when the user enables the feature.
- External images are never loaded automatically. They are retrieved only after the user enables the feature, selects trusted hosts for the current preview, and completes any additional Chrome permission request.
Privacy
- Preview processing takes place in the user's browser.
- The Extension does not store Google Drive file contents, file names, Drive URLs, file IDs, or viewing history as extension preferences.
- Google Drive file contents are not transmitted to, stored on, or analyzed by a server operated by the developer.
- Display preferences are stored in `chrome.storage.local` and are not synchronized through Chrome Sync.

Limitations
The preview may be unavailable when the Extension cannot retrieve or verify the content displayed by Google Drive.
If a file does not meet the supported conditions or the completeness of the displayed content cannot be verified, the Extension returns to the standard Google Drive view.
Because the static preview restricts certain behavior and external resource loading, the rendered result may not be identical to the original HTML.
