Local well data
The current tools read only files you select or text explicitly passed to the in-page API. They do not upload LAS contents or plot settings to a server. Working datasets are held in page memory; there is no application database, local-storage archive or automatic cross-page transfer. Reloading or closing a page discards its working session.
Ordinary website requests
Your browser requests site pages, scripts and images. Some existing pages load fonts from Google Fonts. Hosting and font providers receive ordinary request information under their own policies. This release adds no analytics tracker. The bundled synthetic example is public and is loaded only when you open an example link.
Downloads and sharing
PNG output includes plotted values, labels, well/file names and a shortened source fingerprint. JSON settings include a filename, full normalized-text SHA-256, row count, curve references and selected row indices where applicable. Review these before sharing. Downloads are created locally through the browser; the site does not publish them.
Browser extensions, your AI client and screen-sharing tools have their own access and data handling. This page describes the Petrophysics.io code in v4.
