## What is Crypto Profit Tracker?

Bought Bitcoin at $28,400 and want to know exactly where you stand today? Type in what you paid and today's price — CryptoBook shows your profit or loss on every coin and across your whole portfolio. No exchange login, no wallet address, no API key. Ever.

Every big crypto tracker wants to connect to your accounts and stream live quotes through someone's servers. CryptoBook is the opposite: a private, offline ledger. You enter two numbers per coin — what you paid and what it's worth — and it does the P/L maths. Your holdings never leave your phone.

WHAT YOU GET

• Open the app to the one number that matters: total portfolio value, with profit or loss in dollars and percent
• Per-coin P/L on every row — spot the position quietly dragging your whole portfolio down
• Log each buy as its own lot and your true weighted-average cost basis is calculated for you — DCA without the spreadsheet
• "Updated 3 days ago" stamped on every price, so you always know how fresh your own numbers are
• A donut chart of your allocation — see in one glance that 80% of your money is riding on a single coin
• Your entire ledger — every holding, every lot — out as a CSV in one tap, ready for your records or your accountant

PERFECT FOR

• Long-term holders who check in weekly, not every five minutes
• DCA buyers who want their real average price, not a guess
• Anyone who refuses to hand an app read-access to their exchange or wallet
• Cold-storage owners whose coins never touch an exchange at all

WHY NOT JUST USE A LIVE TRACKER?

Live portfolio apps need your exchange API keys or wallet addresses, and they see every move you make. CryptoBook asks for none of it. The trade-off is honest: you type prices in yourself, as often as you like. In return there is nothing to hack, nothing to leak, and the app works in airplane mode — or anywhere the exchanges don't.

PRIVATE BY DEFAULT

Your ledger is stored only on your device. No account, no sign-up, no cloud, no tracking of what you hold. Delete the app and the data is gone — that is how a private ledger should work.

FULL ACCESS

CryptoBook Pro unlocks unlimited holdings, the allocation chart, and CSV export. Choose a weekly or yearly subscription, or a one-time lifetime purchase.

Add your first coin tonight — two numbers in, and you will know exactly where you stand.

CryptoBook is a manual record-keeping tool, not investment advice. All figures are calculated from prices you enter yourself.
