Is Custom Calendar Background safe?
Custom Calendar Background lets any site set its theme token and adds your Google account email to calendar.useit.today image requests.
A web page can open the extension's exposed options page with a token parameter, causing the extension to save a calendar background configuration in Chrome sync storage. When Google Calendar later loads, the content script applies images from calendar.useit.today and appends the signed-in Google account email as a u= parameter.
