Sign In Once on Your iPhone — Stay Protected Across Foreign Wi-Fi

No personal trip data, emails, or hotel names are ever displayed on the public web. Sign in once below to bind this iPhone for the duration of your trip—or use Tab 3 (Cultural & Chindōgu) and Tab 4 (Public Field Tools) right now without signing in.

Persistent Device Binding

Unlock Your Personal Japan Vault ("Sign In Once for Good")

Zero Passwords on Wi-Fi

Bind this phone once using your iPhone's hardware Secure Enclave (Face ID / Touch ID Passkey) or your Bureau invitation code. Once bound, this tab becomes your Personal Status & Vault tab and unlocks Tab 2 (My Dossier & Route) automatically every time you open the page.

How Your Log & Personal Information Are Secured on Foreign Wi-Fi

Security Architecture

When traveling across airport, Shinkansen, ryokan, and cafe Wi-Fi networks, you should know exactly what protects your connection and why raw personal emails never sit on a web server:

1. Hardware-Bound Token (Zero Wi-Fi Password Sniffing) Signing in once at home creates an encrypted session bound to your iPhone's Secure Enclave over strict TLS 1.3 (`HTTPS` + `HSTS`). You never type a password on public Japanese Wi-Fi.
2. In-Memory Fact Stripping (Zero Raw Email Storage) When the Japan email filter runs, it extracts only the stripped line "Where & When" (city, date window, venue). Raw email bodies and unrelated mail are discarded in memory immediately.
3. Locked to Strangers by Default Anyone opening `bureauofconsideredtravels.mom` without your device token sees zero names, zero hotels, and zero flights—only this sign-in screen and the public translation tools.
4. One-Tap Session & Vault Kill Switch Inside your Status tab, a single button revokes your device token and wipes all stored itinerary anchors from both device storage and the server immediately.

Your Phone’s On-Device AI & Offline Hardware Capabilities

Probing Device...

An iPhone from the last several years (iPhone 12, 13, 14, 15, or newer) carries Apple’s 16-core Neural Engine and Secure Enclave. We checked what your current device can run 100% locally on the phone without waiting on foreign cell towers:

1. Apple VisionKit "Live Text" Camera OCR (On-Device Kanji Reader):
Point your iPhone camera at any Japanese plaque, menu, or train sign to pull text directly off the chip.
Supported
2. On-Device Japanese Voice Synthesis (`ja-JP` Neural TTS):
Speaks polite Japanese aloud to artisans, dojo reception, and curators with zero network delay.
Checking...
3. Secure Enclave Passkey (`WebAuthn` Face ID / Touch ID):
Hardware-backed cryptographic login that cannot be phished on public Wi-Fi.
Checking...
4. Neural Engine / GPU Acceleration (`WebGPU` / `WebGL2`):
Runs local cosine-similarity vector checks and smooth map rendering on-device.

Personal Dossier & Route Vault Is Locked

To protect your itinerary and email extractions on public networks, Tab 2 stays locked until you sign in once on Tab 1 (or turn on Sample Preview Mode).

Cultural Observations & The Chindōgu Log

Kenji Kawakami coined the word Chindōgu (珍道具) for Japan’s habit of inventing hyper-specific, almost absurdly literal contraptions to solve one tiny everyday annoyance. Use this log whenever you spot something unmistakably Japanese—a mechanism, a ritual, a sign, or a piece of over-engineered civic design—and record your theory of why it exists.

4 Sightings Logged

Whether it is a rotating driveway turntable in a three-meter alley, a train conductor pointing and calling at an empty platform (shisa kanko), a bizarrely specific vending machine, or a zero-nail temple joint—snap a photo or jot down what you noticed and why no other culture on earth does it that way.

Tab Four · Stateless On-the-Ground Instruments (Works Logged Out)

Tabletop Voice Bridge · QR Web Reader · Live Text Lens

Public · Zero Personal Data Stored

These three tools require no login and store zero personal information—use them anywhere on the street, at a counter, or in a museum.

Tabletop Mode: Top half is rotated upside-down facing your Japanese counterpart; bottom half faces you. Tap the center bar—your iPhone speaks your question in polite Japanese, invites them in Japanese to reply directly, listens, and translates back into English.

この工房では、工程の途中で不良や異常をどのように見分けているのですか?そのまま日本語でお答えください。
"In this workshop, how do you detect defects mid-process? Please go ahead and reply in Japanese—I will translate into English."

"Translate: how do you detect defects or abnormalities mid-process in this workshop?"
Artisan's Reply (Translated from Japanese): "We listen to the ring of the hammer and watch the steel's heat color before quenching—if the tone shifts, we stop immediately."
