Is G-CAL Highlighter safe?

Clean risk

G-CAL Highlighter fetches public holiday calendars from Google Calendar using your UI language and saved calendar ID.

G-CAL Highlighter uses your browser UI language to look up localized public holiday calendars from the Google Calendar API. If you save a holiday calendar in the options page, it sends that selected calendar ID to Google Calendar to fetch and store the public holiday dates used for highlighting.
