Data handling
Updated November 9, 2026. Hex Edit is a local binary/document inspection workbench created by Brian Scardina / Scardina Cyber Consulting.
Local workspace
The desktop setup selects a source-folder boundary and stores retained investigations separately on the Mac. Originals, working edits, notes and exports may be retained until the user removes them. Plugin removal retains investigation data. Hex Edit’s core code does not add product analytics or a vendor-operated file-upload service.
Codex, ChatGPT and analysis tools
Selections, bytes, annotations and analysis results returned through connected tools can be processed by your host/model provider under its policies. Separate remote MCP deployments receive the data supplied to them. Optional REA/Ghidra and qpdf tools run locally in the desktop configuration. This does not mean that conversations or tool results stay entirely on the Mac.
Website and downloads
This site is hosted by OpenAI Sites. GitHub hosts source and release downloads. Those services may process access metadata and cookies under their own policies. The static site adds no custom analytics or contact form. Sending email to support shares the information you include; avoid sending private binaries, credentials or unredacted evidence.
Your choices and contact
Use authorized files, inspect host permissions, choose an appropriate workspace, and consult the setup/storage guides before deleting retained data. Contact brian@scardina.cc for product support, permissions or private security reports. This page describes current behavior; it is not a compliance certification.
