What stays on this device
My Corridor stores Taiwan base, U.S. base, and direction in twnusa:corridor:v1. Move Plan stores checked items and custom tasks in twnusa:move-plan:v1. The daily FX response may be cached in twnusa:usd-twd:v2.

TWNUSA is designed to work without an account or behavioral profile. This page explains what stays in your browser, what makes a network request, and what you can erase or export.

Ask questions
Ask TWNUSA v1 processes the question in browser memory. The question is not written to localStorage, added to the URL, or sent to an AI service. A Money question can trigger the same fixed /api/fx request the Money tool already uses; the question text is not part of that request.
Network requests
Cloudflare serves the site and can process ordinary request metadata as the hosting/CDN provider. The application also calls its own /api/fx endpoint for the public USD/TWD reference. External government/source links only receive a request when you choose to open them.
What TWNUSA does not build
There is no TWNUSA login, advertising profile, cross-site tracking pixel, server-side Move Plan history, or server-side copy of My Corridor. The site does not need your name or email to use its core tools.
Your controls
Inspect. Export. Restore. Erase.
The Local Data Vault shows the documented TWNUSA browser state, exports My Corridor + Move Plan as JSON, validates imports, and lets you clear each local data category independently.
Privacy model last reviewed: September 10, 2026. If TWNUSA later adds optional cloud sync, accounts, analytics, or an AI service that receives user text, this page should be updated before that feature is presented as production-ready.
