How the product behaves in practice
Common statuses decode locally in the browser. If the local decoder misses, the text passes through GreenLight's decoder API for a fallback explanation. GreenLight does not log or store that pasted text by default.
The receipt number stays local. If you create an account, only the general metadata needed for timeline continuity and alerts syncs to your account.
Once you intentionally log a status entry, that status text becomes part of your saved history and is stored so the timeline, digests, and alerts can work. This is a user action, not background collection.
GreenLight stores only anonymous milestone facts such as case type, milestone name, and elapsed days. No receipt number or user identifier is attached.
The privacy promise in one sentence
GreenLight is designed so the most sensitive identifier in your USCIS journey, your receipt number, never leaves your device, while the less sensitive metadata needed to make the tracker actually useful only syncs when you explicitly opt into an account.
