Frequently Asked Questions

Is my data safe? +
Yes. Everything runs 100% in your browser. Your CSV is never uploaded to any server. We don't store, transmit, or have access to your financial data. You can verify by disconnecting from the internet before using the tool.
Which exchanges are supported? +
We currently support CSV exports from Coinbase, Binance, Kraken, and Gemini. We also support generic CSV formats with columns for date, type, asset, amount, and price.
Can I use this for official tax filing? +
Our reports are designed to help you organize your crypto transactions for tax purposes. The Full Report generates Form 8949 compatible data. However, we recommend consulting a tax professional for complex situations. This tool is for informational purposes.
What cost basis methods do you support? +
The Full Report supports FIFO (First In, First Out), LIFO (Last In, First Out), and HIFO (Highest In, First Out). The free summary uses FIFO by default.
How do I get my CSV from my exchange? +
Each exchange has a different process: Coinbase: Go to Reports > Transaction History > Generate Report. Binance: Go to Orders > Transaction History > Export. Kraken: Go to History > Export. Gemini: Go to Balances > Transaction History > Download.
