Frequently Asked Questions
Is my crypto data safe?
Yes. All data is stored exclusively in your browser's localStorage. Nothing is sent to any server.
Does this show live crypto prices?
You manually enter the current price. This keeps the tool free, private, and zero-maintenance with no API dependencies.
Can I track multiple buy transactions for the same coin?
Yes. Each entry is independent. Add BTC multiple times with different quantities and buy prices to track DCA (Dollar Cost Averaging).
How is P&L calculated?
P&L = (Current Price - Buy Price) × Quantity. Percentage = ((Current - Buy) / Buy) × 100.
What coins can I track?
All major coins (BTC, ETH, SOL, BNB, XRP, ADA, DOGE, DOT, MATIC, AVAX) are pre-listed. Use "Other" for any custom token.
Can I export my portfolio?
Currently portfolio data is stored in localStorage. You can copy the JSON from browser DevTools for backup.
