What stays on your PC
OnlyCash is a Windows program. Your cards, records and history live in a file on your PC, and orders go from there to your platform. Here is what stays, what leaves, and where it goes.
What never leaves your PC
The box: your PC
- Your cards (your accounts)
- Your records (cash, payouts)
- Your history (every trade)
Our servers see
- your OnlyCash account (email)
- your subscription
- how many cards are open
- app version and edition
- update checks
- a wallet’s public address, only if you add one
Only if you add a wallet: public blockchain services read its balance from its public address.
Never on our servers
- your orders
- your trading-platform passwords
- your trading funds
Payment is handled by Stripe.
From click to confirmation
Illustrative walkthrough. No order is sent.
Step 1 / 5
You click
This is the route of the orders OnlyCash sends, from automatic cards.
- You click
- Saved on your PC first — before anything is sent
- Sent to your platform
- Your platform shows what happened
- Filled only when the platform shows it
No confirmation for an opening order → The card says ‘We don’t know’: it never sends that order again, and asks you to look at your platform.
Orders never pass through our servers
Orders go from OnlyCash to your platform through a private channel on your PC. No order is sent to our servers.
Saved on your PC before it is sent
Before OnlyCash sends an order, it saves it on your PC. If the app or the PC stops halfway, the record is still there.
A fill is what your platform shows
A trade shows as filled only when your platform shows it. A ‘received’ reply is not a fill.
An unconfirmed opening order is never sent again
If OnlyCash can’t confirm what happened to an opening order, the card says ‘We don’t know’. It never sends that order again, and asks you to look at your platform.
What our servers see
Our servers see your OnlyCash account (email and the name you chose), your subscription, how many cards are open, the app version and edition, update checks, and a wallet’s public address only if you add one. Payment is handled by Stripe.
Your platform password stays yours
OnlyCash never asks for your trading-platform password. You type it into your platform yourself; OnlyCash never reads it, stores it or sends it anywhere.
OnlyCash never holds your money
OnlyCash never holds or moves your money. Payouts are records you keep; you request them from your prop firm. Wallet balances are read only, with no keys.
Where your records live
Your cards, cash records, payouts and history are kept in a file on your PC, in your Windows user’s folder. The account identities in it are encrypted for your Windows user.
Updates are signed
Updates are signed: the app installs one only if its signature matches ours.
Each account belongs to one card
Each prop account belongs to one card, and stays with it even after you archive the card. On automatic cards you set stop and target before the trade.
