Start by installing the official Ninewin app and confirming the store listing and developer name. Use a unique password, enable two-factor authentication if offered, and avoid public Wi‑Fi for deposits or logins.

• Verify the domain and app updates before first login.
• Set a strong, memorable passphrase and store it in a password manager.
• Limit permissions: decline unnecessary access to contacts or location.
• Enable notifications so you spot unauthorized activity quickly.
• Log out after sessions and clear saved credentials on shared devices.

Routine checks of transaction history and withdrawal limits catch problems early. If anything looks suspicious, contact support immediately and change credentials. Keep the app updated and treat login emails with caution—phishing links often mimic casino messages.
