Account Information

When you create an account, we collect your username, email address, and a securely hashed version of your password (using bcrypt). We never store your password in plain text.

Usage Data

We collect information about how you use NexusAI, including the AI model selected, message count, timestamps, and general usage patterns. This helps us improve the service and enforce fair-use limits.

Your conversation messages are stored in Cloudflare's D1 database, associated with your account, in order to provide chat history functionality. You can delete your chat history at any time from within the application.

Device & Technical Data

We automatically collect standard web server logs including IP addresses, browser type, device type, and referring URLs for security and performance monitoring purposes.
