BTC15 ("we") provides research and trading tools for Kalshi Bitcoin 15-minute markets. This policy explains what we collect and why.
Your email and sign-in details, the profile you choose to show (name, photo, bio), your settings, trades recorded by the app, community posts, feedback, and subscription status from our payment processor. Card details are handled by the payment processor, never stored by us.
Keys you connect are encrypted and only used on our servers to read your balance and place orders you enable. They are never shown back to you or to other members.
Only your public profile, community posts, trades you choose to share, and settings you share with your accepted inner circle. Your orders, balance and keys stay private.
To run the service, improve models, prevent abuse and provide support. We don't sell personal data.
You can edit your profile, turn off community trade posting, disconnect Kalshi, or ask us to delete your account through the Feedback page.
