Exchange Calc Chrome

About

Exchange Calc turns any price on the web into the currencies you care about — without leaving the page.

HOW IT WORKS
1. Select a price on any web page (for example ¥2, $2.15, ₽300, or "CNY 12").
2. Open the right-click menu — the conversion to CNY / USD / RUB is shown right there.
3. Click the menu item to copy the full result to your clipboard.

FEATURES
• Recognizes common price formats: ¥, $, ₽ symbols and CNY / USD / RUB codes.
• Plain numbers are treated as a configurable default currency.
• Live conversion shown directly in the context-menu title.
• One-click copy of the full conversion result.
• A toolbar popup for manual input or reading the current selection.
• Exchange rates are cached locally for up to one hour; if the rate service is unreachable the cached rates are reused.
• Options page to set the default currency for plain numbers and the cache duration.

PRIVACY
Exchange Calc does not collect, store, or transmit any personal data. Selected text is parsed entirely on your device. The only network requests are to public exchange-rate APIs and contain no user information. See the privacy policy for details.

Supported currencies: CNY, USD, RUB.
