NTnS Laptop Monitor

Prepared November 12, 2026

Private operations tool

NTnS Laptop Monitor is an owner-operated tool for New Things n Stuff LLC. It helps the owner review inventory, sales signals, and fulfillment work. It is separate from the public storefront and is not offered as a public Gmail integration.

Optional read-only Gmail reader

The optional reader runs deterministically on the owner’s Windows laptop. After the owner authorizes the selected Google account, it checks that mailbox’s identity, finds Mercari alert messages using local filters, and processes supported authenticated sale and rating notices into minimized records. Unknown or ambiguous message templates stop the scan for review. Email signals alone do not establish complete order, payment, cancellation, or settlement coverage.

Permission and limits

The reader requests exactly https://www.googleapis.com/auth/gmail.readonly. Google’s permission covers the authorized mailbox; the Mercari sender restriction is a local application filter, not a Google-enforced sender-only permission. The runtime uses read requests for the profile, message lists, and selected full/raw messages. It does not send, modify, archive, or delete Gmail messages, change stock, buy products, ship orders, or perform financial transactions.

Private dashboard and notifications

Derived records can be synchronized to the owner’s private OpenAI Sites dashboard, hosted with Cloudflare Workers and D1. When the owner enables device notifications, limited alert content is delivered through the push service selected by that browser. Android Chrome uses Google’s Firebase Cloud Messaging (FCM) push service. Availability and display depend on the browser, operating system, permissions, connectivity, and service status. Enabling this app’s information pages does not connect a mailbox or enable notifications.
