## What is Glyphsieve?

Glyphsieve: Unicode Lab is a focused, fully on-device app. A Unicode inspection and text-security studio for code points, graphemes, normalization, scripts, bidirectional controls, confusables, encodings, and reversible transformations.

KEY FEATURES
- Inspect scalars, grapheme clusters, scripts, and categories
- Compare NFC, NFD, NFKC, and NFKD transformations
- Reveal bidirectional and zero-width control characters
- Screen mixed-script and confusable identifiers
- Decode UTF-8, UTF-16, escapes, and byte sequences
- Complete bundled sample and local comparison workflow
- Local PDF report and Apple system share export
- Original offline technical reference library

ONE-TIME AND PRIVATE
- One paid download; no subscription or in-app purchase
- No account, advertising, analytics, tracking, or developer-operated backend
- Core features and bundled content work offline
- Work remains on device unless you deliberately share or export it through an Apple system interface

Screening aid only. A visual similarity warning does not prove malicious intent; apply a documented identifier and internationalization policy.
