Privacy Policy

Effective Date: January 1, 2026 • Operated by Nexa Frontier dba IsoFluent

1. 100% Client-Side Processing Architecture

IsoFluent Payment Workbench (https://isofluent.com) is engineered as a 100% client-side software engineering and payment protocol diagnostic suite. All ISO 8583 message parsing, EMV BER-TLV decoding, cryptographic key calculations, PIN block translations, and WebGPU Local AI Copilot analyses execute strictly inside your local web browser memory.

Zero Payload Transmission: We do not transmit, collect, inspect, store, or log any hex dumps, ISO 8583 messages, EMV tags, test PANs, cryptographic keys, or logs entered into our workbench tools.

2. Information We Collect

  • Workbench Inputs: None. All tool inputs remain strictly local to your browser tab and are cleared when the session closes.
  • Local Browser Storage: We use standard browser localStorage solely to remember UI preferences (such as sidebar accordion navigation state) and optional browser Cache Storage when you explicitly opt in to downloading the client-side WebGPU AI model weights.
  • Newsletter Subscriptions: If you voluntarily subscribe to The First Byte engineering newsletter via our embedded Beehiiv form, your email address is processed by Beehiiv in accordance with their privacy policy solely to deliver technical articles. You may unsubscribe at any time with one click.
  • Consulting Inquiries: If you contact us via email for consulting services, we retain your business contact details solely to respond to your inquiry.

3. PCI DSS & Enterprise Security Posture

Although IsoFluent Payment Workbench never transmits tool inputs over the network, enterprise users must adhere to internal organization security policies and PCI DSS guidelines by only inputting sanitized logs, non-production sandbox test vectors, and dummy cryptographic keys. Our built-in PCI Log Sanitizer is provided to assist engineers in masking sensitive fields locally before sharing logs internally.
