Your banking information, protected
Writing checks means handling sensitive information — your bank account, your routing number, your business details. Here's exactly how we protect it.
Secure sign-in
Sign in with Google, or with a password that's never stored in plain text — we hash every password with a per-account salt before it ever touches our database, so even we can't see it.
Encrypted in transit
Every page and request to Check Writer 123 runs over HTTPS. Your data is encrypted between your browser and our servers on every single request, with no exceptions.
Your card details never touch our servers
Payment is handled entirely by Square, a PCI-compliant payment processor. Your card number is sent directly from your browser to Square — it's never transmitted to or stored on our servers at any point.
Sessions you control
Signing out immediately ends your session. You can also cancel your subscription or close your account at any time, directly from your dashboard — no phone call required.
We don't sell your data
Your banking information, your checks, and your account details are yours. We don't sell, rent, or share them with third-party advertisers — ever.
