Tango Highlighter stores your known-words list and settings only on your device (browser extension storage or the Userscripts app). No analytics, no tracking, no third-party scripts.
If you activate the optional sync subscription, your known-words list and a random device identifier are sent to the sync server (tango.fanshikun.com) to keep your devices in sync. The license code you enter and the word list are the only data processed. Payment is handled by the payment provider; no payment data reaches the sync server.
Dictionary files are downloaded once from tango.fanshikun.com and cached on your device.
