Illustrative numbers. Yours come from your trades.

Every cycle, rebuilt

Sell the put, get assigned, sell the call, get called away. Thetahouse assembles the legs, lots, sales and dividends into cycles and shows what each one made.

Every number, a receipt

Tap any figure and see the arithmetic. Breakeven is every dollar out minus every dollar in, divided by shares held. Nothing is rounded into a story.

The tax view

IRS-style for an option writer: premium lands when the contract expires, is bought back or assigned; assigned premium moves into the stock basis.

What's expiring

This week's legs up top, days to expiry on every open position, and a nudge when a past-expiry contract still needs its outcome logged.

Six brokers

Schwab, tastytrade, Interactive Brokers, Robinhood, Fidelity and E*TRADE transaction exports. Rows that can't be read are listed with the reason, never dropped.

Nothing leaves your phone

No account, no server, no analytics. Your ledger is on your device and in your own iCloud. The privacy label is "Data Not Collected."
