Q. Will this addon send URLs I am visiting?
A. No. Platform Status Indicator does not send any URLs you are visiting to any servers. Instead, Platform Status Indicator downloads platform status data which contains every URL of specification that Platform Status Indicator supports. So Platform Status Indicator does not need to send any URLs to any servers.
