Privacy Policy
1. Introduction
Matcha ("we", "our", or "us") is an iOS and Android application that uses artificial intelligence to help you discover clothing colors and combinations that complement your skin tone. This Privacy Policy explains what information we collect, how we use it, and your rights regarding your data.
By using Matcha, you agree to the collection and use of information as described in this policy. If you do not agree, please discontinue use of the app.
2. Information We Collect
Account Information
When you create an account, we collect:
- Email address — used to identify your account and send account-related communications
- Display name — the name shown on your profile within the app
- Authentication provider — whether you signed in via email/password, Apple Sign In, or Google Sign In
Photos and Images
When you scan a clothing item or outfit, the image is transmitted securely to our backend (a Supabase Edge Function) which forwards it to OpenAI's GPT-4 Vision API for color analysis. The image is used solely for that analysis and is not permanently stored on our servers or OpenAI's servers after analysis is complete.
Skin Tone Preference
If you select a skin tone within the app, this preference is stored in our database to personalise your color recommendations. You can update or remove it at any time from your Profile settings.
Saved Looks and Scan History
Analysis results you choose to save (your "looks") are stored in our database and associated with your account. This includes color recommendations, outfit descriptions, and metadata such as the date of the scan.
Usage Data
We collect your daily scan count and scan event logs to enforce free-tier limits and to understand how the app is being used. This data is associated with your account.
3. How We Use Your Information
- To provide and operate the Matcha service
- To generate personalised color analysis and recommendations
- To enforce daily scan limits for free-tier users
- To save and retrieve your look history across sessions and devices
- To communicate with you about your account if necessary
- To improve the app based on aggregate, anonymised usage patterns
4. Third-Party Services
Supabase
We use Supabase for authentication and database storage. Your account data and saved looks are stored on Supabase infrastructure. Supabase is SOC 2 compliant. See their Privacy Policy.
OpenAI
Images you submit for analysis are sent to OpenAI's API. Per OpenAI's API data usage policy, data submitted via the API is not used to train their models and is not retained after the request is fulfilled. See OpenAI's API Data Usage Policy.
Apple Sign In
If you choose to sign in with Apple, Apple may share your name and email address with us as part of the authentication flow. See Apple's Privacy Policy.
Google Sign In
If you choose to sign in with Google, Google authenticates your identity via OAuth. We receive only your email address and basic profile info from Google. See Google's Privacy Policy.
5. No Sale of Data
We do not sell, rent, or trade your personal information to any third party for marketing or commercial purposes. Ever.
6. Data Storage and Retention
Your account data is retained for as long as your account exists. If you delete your account, your personal data and saved looks will be permanently deleted from our database within 30 days.
To request account deletion, email us at matandaphiri64@gmail.com with the subject line "Delete My Account".
7. Your Rights
You have the right to:
- Access — request a copy of the personal data we hold about you
- Correction — update your display name directly in the app; contact us to correct other data
- Deletion — request permanent deletion of your account and all associated data
- Portability — request an export of your saved looks data
To exercise any of these rights, contact us at matandaphiri64@gmail.com.
8. Children's Privacy
Matcha is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe a child has provided us with personal information, please contact us and we will delete it promptly.
9. Security
We implement industry-standard security measures including encrypted data transmission (HTTPS/TLS), secure authentication via Supabase Auth, and row-level security on our database so users can only access their own data. No method of transmission over the internet is 100% secure, and we cannot guarantee absolute security.
10. Changes to This Policy
We may update this Privacy Policy from time to time. When we do, we will update the effective date at the top of this page. Continued use of the app after changes constitutes acceptance of the updated policy. For significant changes, we will notify you within the app.
