Last updated: June 21, 2026
SUP ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the SUP mobile application and website (collectively, the "Service"). Please read this policy carefully.
1. Information We Collect
Information You Provide Directly
- Account information: Email address, display name, username, and password when you register.
- Profile information: Profile photo, bio, city, and other optional details you choose to add.

Information Collected Automatically
- Device information: Device type, operating system version (Android), and unique device identifiers.
- Usage data: Features used, pages viewed, listing interactions, and session durations.

- Push notification tokens: Expo push tokens to deliver in-app notifications.

2. How We Use Your Information
We use the information we collect to:
- Create and manage your account and authenticate your identity
- Enable you to post listings and communicate with other users
- Send transactional emails (OTP verification, password reset) via Resend
- Send push notifications about messages, offers, and saved search matches
- Display your public profile and listings to potential buyers or sellers
- Improve our platform, fix bugs, and develop new features
- Detect and prevent fraud, abuse, and violations of our Terms of Service

3. How We Share Your Information
We do not sell your personal information. We share data only in these circumstances:
- With other users: Your public profile (display name, city, average rating) and active listings are visible to all users. Messages are visible only to participants in that conversation.
- Service providers:
- Railway (hosting infrastructure — PostgreSQL database and API server)
- Cloudinary (image storage and optimization for listing photos and avatars)
- Resend (transactional email delivery for OTPs and notifications)
- Legal requirements: We may disclose information when required by law, court order, or government authority under Indian law.
- Business transfers: In connection with a merger, acquisition, or sale of assets, your information may be transferred with appropriate notice.
4. Data Security
We implement appropriate technical and organizational measures to protect your data:
- Passwords are hashed using bcrypt with salt rounds — never stored in plaintext
- Authentication tokens use RS256 JWT with short expiry (15 minutes for access tokens)
- All data in transit is encrypted via HTTPS/TLS
- Sensitive credentials are stored using Android's Secure Enclave via Expo SecureStore
- Database access is restricted to our Railway internal network
No method of transmission over the internet or electronic storage is 100% secure. We encourage you to use a strong, unique password and enable biometric authentication within the app.
