Please read these Terms of Use ("Terms") carefully before downloading or using the Matcha mobile application, developed by Creative Adventures Lab SASU ("we", "us", "our") (available on the App Store and Google Play, also referred to as "Matcha", the "App", or "Service"). By installing or using the App, you agree to be bound by these Terms. If you do not agree, do not install or use the App.

Our Privacy Policy explains what the App does with your information — in short, it stays on your device. It forms part of these Terms, so please read it as well.

1. Description and Scope

Matcha is a personal matcha tasting journal, brew timer, and ritual tracker for iOS and Android devices. The App allows you to:

• Maintain a cellar of matcha tins, with brand, name, origin, harvest year, grade, weight, price, status (sealed / open / finished), an optional photograph, and free-text notes;
• Run a brew timer for the four built-in prep styles (usucha, koicha, matcha latte, iced matcha), with optional per-phase timing overrides and an adjustable matcha-grams dose;
• Record a tasting journal for every brew, including six taste-axis sliders (umami, sweet, body, finish, astringent, vegetal), an auto-derived overall rating on a 0–10 scale, and free-text notes;
• See a session detail view with a radar visualisation, brew parameters, and a link to the originating tin;
• Track a ritual of daily check-ins at 60 minutes and 180 minutes after a brew, capturing focus, mood, energy, and an optional note;
• Watch your freshness clock on each open tin, with a coloured tier badge (peak / fading / use soon / past peak) and two follow-up reminders scaled to the tin's configured freshness window (one at approximately 77 % of the window, one at the window end);
• Browse an editorial recipes library of variations on the four basic prep styles;
• Manage custom prep profiles (saved brew configurations) and export your entire journal as CSV or a versioned JSON backup.

The App stores all of your personal data locally on your device in a sandboxed SQLite database and in AsyncStorage. There is no Matcha account, no sign-in screen, no email/password registration, no Sign in with Apple, and no Sign in with Google. We operate no server-side database of your journal or personal content. The only backend interactions are (a) subscription verification handled by Apple's StoreKit 2 or Google Play Billing on our behalf and, (b) a small European service that receives Apple's server-to-server notifications, including a guardian's grant or withdrawal of consent where the operating-system age-assurance flow is active. Your device never contacts it, and it keeps no database: only a short-lived operational log, with no identity and none of your journal content (see the Privacy Policy, Section 2.7).

The App is offered as a freemium service:

• Free (no subscription required): up to 3 tins in the cellar and 10 sessions in the journal, all four prep styles (usucha, koicha, matcha latte, iced matcha), the streak and 7-day dot strip, the freshness clock, the ritual check-in flow, taste rating (the six taste-axis sliders and overall score), and full CSV / JSON export of your journal. This tier is available indefinitely.
• Matcha Pro (paid subscription): an unlimited cellar and journal, plus the insight layer on top of the free experience — the taste radar visualisation, the caffeine tracker (including logging teas you drank elsewhere), the weekly focus curve, smart insights and pattern cards, custom prep profiles, and the full recipe library (the everyday usucha recipe stays free). Expiry or cancellation returns you to the free experience above (capped at 3 tins / 10 sessions going forward), not to a blocked state; tins, sessions, and exports already on your device remain fully available and exportable even past the cap.

New users are offered a one-time seven (7) day free trial of Matcha Pro when they access the paywall — either via Settings → Upgrade to Pro or when they tap a Pro feature (such as opening the taste radar or the caffeine tracker). The trial is optional — the App may be used on the free tier without ever subscribing.

These Terms govern your use of the App on any device. They do not govern any third-party services (such as the Apple App Store or Google Play Store) whose own terms apply separately.
