Privacy Policy

Winbannu ("we," "our," "us") explains in this Privacy Policy what information we collect when you use the Winbannu app and website (winbannu.com), and how we use it.

Information We Collect

• Phone number — required at signup to create and identify your account. We use this to prevent duplicate accounts (e.g., re-registering to reset a trial). We do not currently verify phone numbers via OTP/SMS.
• Account and usage data — trading activity within the simulation (paper trades, watchlists, alerts you set), stored to provide the app's core features.
• Payment reference information — if you subscribe to Pro, your payment is processed via a UPI payment link (GPay for Business). We may receive a payment confirmation/reference but do not store your card, bank, or UPI PIN details — these are handled entirely by the UPI/payment provider.

How We Use Your Information

• To create and secure your account
• To provide and improve app features (charts, alerts, portfolio tracking)
• To manage your subscription/trial status
• To respond to support requests

We do not sell your personal information to third parties.

Where Your Data Is Stored

Account and app data is stored using Supabase (our backend data provider). Payment processing is handled by our UPI/payment provider; we do not store your financial account details ourselves.

Your Choices

You can contact us at adi.shiv999@gmail.com to:

• Request a copy of the data we hold about your account
• Request deletion of your account and associated data

Children's Privacy

Winbannu is not directed at children under 18. We do not knowingly collect data from minors.

Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date.
