Frequently Asked Questions

Is it safe to connect my bank?

Yes. Centinel uses Plaid to connect to your bank—the same technology trusted by Venmo, Robinhood, Coinbase, and millions of users. Here's how Plaid keeps you safe:

  • Encryption: Your data is encrypted in transit and at rest.
  • Read-only access: Centinel can only read your account data—we can't move money or make changes.
  • Secure credential handling: Centinel never sees or stores your bank login credentials.

How is Centinel different from a budgeting app? Should I use both?
Budgeting apps track your spending behavior—swipe your credit card today, it's logged today. Great for understanding spending habits, but they don't forecast when bills actually hit your checking account.

Centinel uses your cash flow to track when money hits or leaves your checking account. It runs a 60-day forecast that shows your projected available cash and flags upcoming shortfalls before they happen.

Yes, use both! Use a budgeting app to stay on top of spending habits. Use Centinel to minimize idle cash and spend with more confidence—without dipping below your Floor or risking an overdraft. They solve different problems.
How does Centinel's forecasting work?
Centinel forecasts your checking account balance by simulating your future cash flow day by day. It takes your current balance, then automatically applies each scheduled expense and income on the date it’s expected to occur.

The result is a running 60-day projection of your balance that shows your projected available cash and flags if you’re projected to dip below $0 or your Floor—so you see issues early, not after the fact.
My cash flow changes relatively frequently. How does Centinel handle this?
Centinel is built for real life—where paychecks change, bills shift, and plans aren’t always predictable. Adjust a single paycheck, edit your recurring income, or add one-time expenses anytime. Centinel instantly updates your forecast so it stays current.
Can Centinel guarantee I’ll never overdraft?
No app can guarantee you’ll never overdraft—and Centinel won’t pretend to.

Overdrafts can still happen when unexpected transactions hit or when you ignore alerts. Centinel can’t see or control every real-world decision or unexpected transaction, but it can forecast your balance and flag risks ahead of time based on what it knows. Outcomes depend on data provided and user action. Think of Centinel as a tool, but you’re still the one in control of your money.
