Gbook Styler ("the Extension") respects your privacy. This policy explains what data the Extension handles.
None. The Extension does not collect, transmit, or store any personal information, browsing history, book content, or usage analytics.
Your preferences (font size, line height, column width, margins, theme, font family, text alignment) are saved locally in your browser using Chrome's storage.sync API. This data:
The Extension makes no network requests of its own.
When you select a Google Font from the dropdown, the browser loads the font stylesheet from fonts.googleapis.com — this is a standard browser behavior for web fonts, not initiated by the Extension's code.
