## What is TintBook?

TintBook is the offline formula book for salon colorists.

Save every client’s color mix by zone — roots, mids, ends, toner — with brand, shade, grams and developer. When they return, start from the last mix in one tap. History stays on your phone.

Built for colourists who work behind the chair:
• Zone formula cards, not a bloated CRM
• One-tap “start from last mix”
• Client history you can search by name or shade
• Share a formula as text or export a JSON backup
• Fully offline — no account, no server

PRIVACY
TintBook has no account and no server. Formulas never leave your device.

TINTBOOK PRO
Free: 5 clients with full history. Pro: unlimited clients, clean export, offline forever.

TintBook Pro is an auto-renewing subscription: $4.99/month or $29.99/year (with a 7-day free trial on the annual plan). Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel in your Apple Account settings.
