Who we are
Chacha (“the app”) is a matcha check-in and discovery app operated by Scott Martin, Mexico City. Contact: support@matchacha.app.
Data we collect
- Account data: email address, display name, username (via Supabase Auth; Apple Sign-In users may use Apple's private relay email).
- Content you create: check-ins, ratings, taste profiles, reviews, comments, photos, saved places, shelf items, and place–matcha identifications.
- Location: used while the app is open to find matcha places near you. We store only the coordinates of places you interact with — never a trail of your movements.
- Push token: if you enable notifications, an Expo push token is stored to deliver like/comment/follow notifications.
What we don't do
No advertising SDKs, no sale of personal data, no background location tracking.
Sharing & visibility
- Public check-ins, ratings, and your profile (name, username, avatar) are visible to other users. Private check-ins are visible only to you.
- Infrastructure providers process data on our behalf: Supabase (authentication, database, photo storage), Railway (API hosting), Google Maps Platform (maps and place search), Expo (push notifications), Vercel (this website).
- Place photos and reviews labeled “via Google” are provided by Google Maps and remain Google's content; we do not store them.
Affiliate links
Some “where to buy” links may be affiliate links, meaning Chacha can earn a commission on qualifying purchases at no extra cost to you. This never affects scores or rankings — those come only from community check-ins.
Your rights
- Delete your account any time in the app: Profile → Settings → Delete Account. This permanently removes your account and all associated data, including from our authentication provider.
- Report content and block users directly in the app; reports are reviewed promptly.
- For data questions or export requests, email support@matchacha.app.
