Security & trust

Your money stays
completely safe.

FlowCheck is built with security as the first priority — the same standards used by major banks, because your financial data deserves nothing less.

256-bit AES encryption

All data is encrypted in transit with TLS 1.3 and at rest with AES-256 — the same standard used by major financial institutions worldwide.

Read-only bank access

FlowCheck uses Plaid for bank connectivity. We can only read your transactions — we cannot initiate payments, transfers, or any changes to your accounts. Ever.

iOS Keychain storage

Sensitive credentials are stored in the iOS Keychain — hardware-backed encrypted storage that even FlowCheck cannot read without your biometric.

Powered by Plaid

Bank connections are handled entirely by Plaid, trusted by over 12,000 apps including Venmo, Robinhood, and Betterment. Your credentials never touch FlowCheck's servers.

Firebase authentication

Accounts are secured by Google Firebase with rate limiting, brute-force protection, token revocation, and session monitoring built in.

Face ID & auto-lock

FlowCheck locks automatically and requires Face ID or Touch ID. The app blurs your financial data the moment you switch apps — before iOS takes its screenshot.
