Privacy and browser-local calculations
How the inventory lab, curve inputs, downloads, hosting requests and external links handle information.
The lab performs calculations in the current browser page. It does not transmit curve inputs or search text to an analysis service, and it does not create a user account or store an input history.
Inputs and exported files
The inventory selector reads a fixed public dataset from this site. The curve worksheet evaluates numbers entered on the page. Both keep their state in page memory; the release uses no application cookies, localStorage or remote input database. Reloading the page resets the example. Downloads are generated when requested and become files under the user’s control.
The worksheet requires no trading credentials, API keys, personal identifiers or confidential portfolio data. Browser extensions, device software and downloaded-file handling have their own behaviour outside this application. Use nonconfidential assumptions for an educational exercise.
Hosting and navigation
Cloudflare serves the website, data and scripts and can process ordinary connection information to deliver and protect them. Local calculation does not mean that a website visit leaves no hosting records. This edition includes no analytics tracker or advertising pixel. Search filters a static index in the browser after that index loads.
Following an external source or inquiry link takes the reader to another service with its own policies. Featured links use fixed referral parameters naming this publication and campaign; those parameters contain no worksheet input or search phrase. The site starts no scheduled data refresh, monitoring job or background process on the reader’s computer.
Questions and changes
This notice describes the initial edition dated October 16, 2026. A later feature that sends or stores inputs would require a changed implementation and notice. Report a concern through the contact identified on the About page, with only the information needed to explain the issue.
Source notes
Source dates and scope matter. Historical inventory observations are retained snapshots; forecasts and synthetic curve assumptions are labelled separately. No investment outcome or product coverage is implied.
