Your cost basis after every roll
Raw and premium-adjusted basis side by side. A roll is recorded as one event with two legs, a close and an open, so the basis moves only by what you actually kept.
For covered-call and wheel investors
Premium collected is not profit.
yourfinance shows what you have actually realized, your cost basis after every roll, and what needs a decision this week. It runs on your Mac or Windows PC, with no broker login and no automatic trading.

One covered-call roll, worked end to end. Demo data on a made-up ticker, not a performance claim.
If your spreadsheet reports only the first number, it is not tracking the risk.
How it works
Three steps, once a week
- Record or import. Enter your puts, calls and shares, or import your broker's CSV.
- See what you kept. Realized income apart from premium at risk, and your basis after every roll.
- Decide with the facts. The Decision Desk lists what needs you and what is missing before you compare hold, close or roll.
What it does
Bookkeeping that knows how the wheel works
One weekly list of decisions
The Decision Desk ranks what needs you: past expiries, calls due this week, planned reviews, policy breaches, and what is missing before hold, close or roll can be compared.
Realized, apart from at risk
Income by month counts what is closed and kept. Premium on an open option stays at risk until it expires, is bought back, assigned or called away.
Imports without guessing
IBKR, DEGIRO, Trading 212 and Trade Republic CSVs, or the yourfinance template. Anything the file cannot say exactly, the preview asks you before recording.
Exports for the year
Tax-year exports, CSV, an HTML report and a calendar (ICS) of expiries. They are records for you or your adviser; the app does not calculate tax.
Private by design
Everything stays on your computer. There is no account and no server holding your records. Connectors, crypto prices and the phone link are off until you switch each one on.

Questions
Before you download
Is it a subscription?
No. The download is a 10-day free trial with every feature. Beginner is $20 and Pro is $50, paid once, with updates through version 1.x.
Does it need my broker login?
No. You record trades yourself or import your broker's CSV. Pro adds optional, read-only connectors that use keys you create at your broker; they stay in your computer's keychain.
Where are my records kept?
On your computer, in files the app writes atomically and backs up at every start. There is no yourfinance account, and nothing is sent anywhere unless you switch a network feature on.
Does it tell me what to trade?
No. It records, calculates and asks the right questions before you decide. It does not recommend trades, predict prices or place orders.
What happens when the trial ends?
The app becomes read-only: every record stays visible, and exports and backups keep working. Paste a key in Settings → Licence to continue. Nothing is deleted.
Which computers does it run on?
Macs with macOS 13 or later, with Apple Silicon or Intel, and PCs with Windows 10 or 11, 64-bit.

The download is the whole application. Buy a key only when it earns it.
