Crypto Portfolio Tracker (free, saves your data in your browser)
Record the coins you own and your purchase price to see your portfolio value and current profit. No account needed, and your data never leaves your device.
Data is saved in this browser only; if you clear browser data or change device you will lose it. Prices are approximate and for tracking only.
How does the tool work?
You add each coin you own and its quantity, and optionally its average buy price. We fetch current prices from CoinGecko and calculate the value of each coin, the total and the profit or loss. We send your data nowhere, and it is saved in local browser storage.
Tips
The tool is not a substitute for your accurate tax records. To find an average buy price use the average price calculator, and to split your portfolio read the diversification article.
