What is the Legal and Brand Engine suite in DeckMedic?

The Legal and Brand Engine is Station 6 of DeckMedic — three specialized tools for making PowerPoint decks legally and brand-policy compliant before external distribution: Contrast Validator (WCAG 2.1 AA accessibility check and auto-fix), Confidentiality Watermarker (injects a locked diagonal CONFIDENTIAL shape into the Slide Master), and Reviewer Reset (permanently deletes all comments and reviewer author records). All tools run free, in-browser, with zero upload.

What is WCAG 2.1 AA contrast compliance and why does it matter for PowerPoint?

WCAG 2.1 AA requires a contrast ratio of at least 4.5:1 between text color and background color for normal text. PowerPoint presentations used in ADA-regulated contexts — government agencies, publicly traded companies, universities receiving federal funding, and any organization covered by Section 508 — must meet this requirement. The Contrast Validator scans every text run in your PPTX and auto-darkens any color that fails the threshold.

Why should I watermark a PowerPoint via the Slide Master instead of adding text boxes to individual slides?

The Slide Master is the single parent XML file from which all slide layouts inherit. Injecting a CONFIDENTIAL shape into the Slide Master means every slide — current and future — automatically displays the watermark. Per-slide injection would require editing every slide individually and would miss slides added by reviewers after watermarking.

Are all three tools in the Legal and Brand Engine free?

Yes. All three tools are free with no account required. PPTX files are processed locally in your browser using Web Workers. No data is uploaded to any server.

DeckMedic · Legal & Brand Compliance Suite

Legal & Brand Engine
PPTX Accessibility, Protection & Cleanup

Three legal and brand compliance risks live in every deck distributed externally: text that fails WCAG 2.1 AA contrast (an ADA violation), no confidentiality marking on pre-signature materials, and reviewer names and internal commentary embedded in the ZIP. This suite fixes all three — in your browser, with zero server contact.

The Problem

✗ Light gray text on white backgrounds fails WCAG 2.1 AA (4.5:1 ratio) — ADA Title III and Section 508 liability on every external deck
✗ Pre-NDA decks sent without confidentiality markings — no legal protection if slides leak before signature
✗ Reviewer names, timestamps, and internal comments sit inside the PPTX ZIP — GDPR Article 4 personal data sent to every recipient

The Fix

✓ Contrast Validator scans every text/background pair and flags each failure with exact WCAG ratios — before you send
✓ Confidentiality Watermarker stamps every slide in a single pass — no manual work, no missed slide
✓ Reviewer Reset strips all comment XML from the file — names, timestamps, and annotations gone permanently
