Morningside Privacy Policy
This page describes the intended privacy boundary for the Morningside Excel add-in project by NSC Labs. Morningside is not currently published to Office Online.
Overview
Morningside is a prepared Excel Office add-in project for local workbook history. It is intended to help users capture workbook moments, compare selected cells or ranges, and restore selected workbook states. Public Office Online distribution is planned but not live yet.
Workbook data
The intended Morningside design does not send workbook contents to an NSC Labs backend.
When deployed, captured workbook frames are intended to be stored inside the user’s workbook in a hidden worksheet named _morningside_ledger.
The intended workbook-history boundary is workbook-local unless the user chooses to share, export, upload, or sync the workbook through Microsoft Excel, OneDrive, SharePoint, email, or another service outside Morningside.
Hosted add-in files
Morningside is not currently published to Office Online. When deployed, the hosted Morningside page is intended to serve static add-in files, including HTML, JavaScript, CSS, and icons.
The hosted page would be used to load the Excel task pane. It is not intended to receive, store, or process workbook contents.
No workbook-data backend
Morningside is not intended to use a workbook-data backend, SQL database, LLM processing, or cloud workbook processing.
Local storage
When deployed, Morningside may use local browser or Office host storage as a cache or fallback when workbook sheet access is unavailable. The primary workbook history ledger is intended to be stored inside the workbook.
Server logs
Like most websites, the hosting provider may maintain standard server logs, such as IP address, requested files, timestamps, and user agent, for security and operational purposes.
Static file requests for Morningside pages may appear in ordinary server logs when pages, scripts, stylesheets, or icons are loaded. These logs do not contain workbook contents.
Analytics and advertising
Morningside is not intended to use advertising trackers or behavioral analytics scripts.
Data sharing
NSC Labs does not sell personal data. Morningside is not intended to transmit workbook contents to NSC Labs servers.
