Data Collection
Bitcoin DCA Calculator is a client-side tool. Your calculator inputs (investment amount, frequency, dates) are processed entirely in your browser. We do not collect, store, or transmit your personal financial data to any server.
When you use the "Live API" price mode, your browser makes requests to public cryptocurrency exchange APIs (Kraken, Coinbase) to fetch historical price data. These requests are proxied through our server to enable caching, but no personally identifiable information is included in these requests.
