Fail-Open Safeguards & Privacy

How WS Checkout Control guarantees checkout uptime and handles buyer signals with zero IP storage.

WS Checkout Control is built with mission-critical reliability to ensure your store's checkout is never disrupted.

100% Checkout Continuity

Even if an invalid combination of hide rules is configured, the fail-open safeguard ensures at least one valid payment and shipping method remains visible so orders are never lost.

Fail-Open Guard Architecture#

Before any WASM function output is emitted to Shopify Checkout, the runtime evaluates whether the resulting payment and shipping list would be empty. If empty, the function suppresses the hide action and logs a safeguard diagnostic alert.

In-Memory IP & Privacy Classification#

Customer geo-location signals are evaluated strictly in-memory during WASM execution without writing IP addresses or persistent identifiers to disk, complying with global privacy laws.
