Four steps, in order — because order is the privacy model

1. 1

   OCR happens on the phone

   The photo is read on-device and deleted right after. It never touches a server.

2. 2

   Only text travels

   Registration-number patterns are masked on the phone before the Korean text is sent over HTTPS.

3. 3

   Analysis is schema-forced

   The AI runs in a read-only sandbox and must answer in a strict JSON schema — no freeform guessing.

4. 4

   Every claim is evidence-checked

   If an action's Korean quote isn't found in your notice, the server throws that action away. Reminders stay local on the phone.
