Keep frequent currencies nearby: customize the five quick-access currencies to match the pairs you use. Available currencies are listed in the app.

## Privacy and data

CoinCalc has no advertising, analytics, cross-app tracking or profiling. Calculator inputs and results are processed on the device.

Market requests transmit selected symbols and necessary connection information. Optional price alerts use technical delivery data and the rules you create; subscription verification uses Apple-signed purchase information. Optional Pro sync uses your private iCloud account. The privacy policy explains these services and deletion controls.

## Market data and limits

Conversion uses public market quotes against USDT. Quotes are informational, may be delayed or unavailable, and may differ from the price of an executed trade. USDT is a cryptocurrency and is not the same asset as US dollars.

CoinCalc does not substitute fabricated rates when market data is unavailable. The app does not execute trades, hold assets, connect to exchange accounts or provide investment advice.
