Engineering Principles

Local-First Data Ownership

User projects, salon client formulas, and rehearsal timings are stored directly on the user's device using Apple's native data frameworks. Core instruments operate offline without mandatory cloud accounts.

Explicit Permission for Structured Parsing

Optional assistive import features execute only after explicit, granular user consent in accordance with Apple App Store Review Guidelines, using enterprise paid-tier inference with zero model training retention.

Transparent Subscription Licensing

Every application states full trial duration, renewal pricing, and one-tap cancellation paths upfront through Apple StoreKit 2 and authorized merchant-of-record billing partners.
