What it does, what it deliberately doesn't, and how your data is handled.

Nothing. It's a personal project - no paid tier, no ads, and nothing sold on.

No, and that's deliberate. Trades are entered by hand, which means it never needs - or asks for - your exchange keys.

No, and that's deliberate - the same answer as the exchange question, for the same reason. This is a journal of the trades you entered, not a price terminal. Realised P&L on a closed trade is exact because you supplied both prices; an open position is left unpriced rather than guessed at, and a zero would be a claim the app can't make. Close the trade to see its real result.

From your trading amount and leverage rather than the raw price move. Position size is amount × leverage, and the percentage move is applied to it - so a 2% move at 10× is a 20% result on your margin, in the direction of your position.

MMR is your maintenance margin rate - the share of position value your exchange requires you to keep. It’s used with your leverage and any extra margin to estimate the price at which the position would liquidate. A planning figure, not a promise from your exchange.

Closing writes the matching profit or loss transaction into the wallet, so the balance reflects your trading without any double entry from you. Re-opening the trade removes that entry again.

No other user, ever - every request is authenticated on the server and every query is scoped to your account, so the data is isolated per user at the data-access layer, and the browser never talks to the database. Being straight with you about the rest: the trades are stored in an ordinary database, not encrypted so that only you hold the key, so whoever operates the service can technically read them - as is true of any hosted app. Nobody does as a matter of course, and no third party is given access. The privacy policy says exactly what is and is not encrypted.

No, and it would be wrong to imply otherwise. Traffic is encrypted in transit (HTTPS) and the database is encrypted at rest by the host, which protects it from interception and from a stolen disk. Your password is hashed and cannot be read by anyone, including us. But the trades themselves are stored as ordinary readable rows - they are not encrypted with a key only you hold. True end-to-end encryption would mean the server could not calculate your P&L, win rate or chart, and a forgotten password would destroy your data permanently.

Any time. Trades and transactions export to Excel, and the export respects whatever filters you have applied.

From Settings. Deleting removes your profile, wallets, trades, transactions, goals and settings with it.
