CurrencyBar is a currency-conversion browser extension. It contains no advertising, analytics, tracking, telemetry, or code that sends information to the developer.
Selected currencies, their order, and the active currency are stored in Microsoft Edge synchronized extension storage. Edge may synchronize these preferences through the signed-in Microsoft account when sync is enabled. Cached exchange rates and refresh timestamps are stored locally in the browser profile. An optional user-supplied Twelve Data API key is stored locally and is not synchronized by CurrencyBar. Typed conversion amounts are held in memory only.
