Kalshi retains: your address, phone, encrypted SSN, and email. Kalshi retains these for required audit and regulatory purposes.
Kalshi releases: The image of your ID gets sent to a third-party partner that provides KYC services, so Kalshi does not receive or store your ID image or the information on the ID.
Kalshi’s bank connection is powered by Aeropay, which means your bank information is stored and maintained by them.
