No. Toolhast performs permanent vector burn-in compliant with ISO 32000 standards. Unlike cosmetic viewer highlights that merely place a transparent overlay, Toolhast draws solid, opaque vector blocks directly into the page stream and strips metadata. The obscured content cannot be copied, selected, or recovered by any standard PDF software.

Black-Out applies a solid black block over text, making it explicitly clear that confidential information has been excised, which is the legal standard for court filings. White-Out applies a clean white mask that blends invisibly with white paper backgrounds, which is ideal for redacting signatures or corporate letterheads.

This prevents accidental data leaks where sensitive organizational details or drafting usernames might otherwise remain hidden inside the PDF file trailer.

No. Toolhast operates under a strict client-side zero-upload privacy architecture. All coordinate mapping, vector rectangle drawing, and document recompilation execute entirely within your local browser memory sandbox.
