Security & privacy

Designed to hold as little as possible.

BYP keeps your keys and your portfolio on your device wherever it can, encrypts what it syncs, and never acts on your accounts by itself.

How BYP protects you

Keys stay on your PC

In the Windows app, broker credentials and data or AI keys are stored in the Windows Credential Manager and sent only to the provider they belong to. The web app does not accept broker keys.

Encrypted before upload

Optional sync in the Windows app encrypts your preferences, watchlists, saved views, notes and workspace state on your device with AES-256-GCM, using a key derived from a passphrase only you know (PBKDF2-SHA256, 600,000 iterations). The server stores ciphertext it cannot read.

A strict allow-list

The desktop app’s content-security policy lists every host it may contact. Anything else — including an injected script trying to send data elsewhere — is blocked.

Diagnostics without secrets

Diagnostic reports you choose to send exclude keys, account numbers and holdings.

You control your account

See your signed-in devices, sign out of every device at once, or delete your account and its cloud data from Settings.

Nothing trades on its own

Orders can be sent only through Alpaca, only from the Windows app, and only after you review and confirm. Captain Umro and alerts cannot place orders.

Encrypted sync

What sync does today — and what it doesn’t.

Sync is optional and available in the Windows app. It covers preferences, watchlists, saved views, notes and workspace state — never broker keys, API secrets, orders or payment data. Your data is encrypted on your device before it is uploaded, and only someone with your passphrase can decrypt it. If you lose the passphrase, BYP cannot recover the synced data.

  • The Android app does not sync your workspace today; treat your phone and your PC as separate.
  • If two devices change the same data, the most recent change wins. Sync is designed for one primary computer.
  • Deleting your account deletes its synced ciphertext from BYP’s servers. Data kept only on a device stays there until you remove it.
