1. Information We Collect
1.1 Account Information
When you create an account via Clerk, we receive your name, email address, and profile picture. Clerk handles credential storage and authentication — we do not store your passwords.
1.2 Profile Information
When you use our community features, you may provide additional profile information including a display name, bio, expertise areas, location, company, website URL, and social media links (LinkedIn, GitHub, Twitter). This information is publicly visible on your profile page.
1.3 User-Provided Content
We collect the system design prompts you submit, your responses to clarifying questions, chat messages within design sessions, discussion posts, and comments. Prompts and chat messages are sent to AI providers (Google Gemini) for processing.
1.4 Community Interactions
We collect data about your community interactions including follows, upvotes, comments, discussion participation, and activity feed events. This data is used to power features such as notifications, leaderboards, reputation scores, and personalized feeds.
1.5 Analytics & Usage Data
We use Mixpanel to collect usage analytics including:
- Page views and navigation patterns
- Feature usage events (e.g., session starts, mode selection)
- Session recordings (screen interactions within the app)
- Device type, browser, and general location (country/region)
Mixpanel data is stored in your browser's localStorage. Session replays mask password fields and elements marked with the "mp-mask" CSS class.
1.6 Automatically Collected Data
Our hosting provider (Vercel) automatically collects standard server logs including IP addresses, request timestamps, and HTTP headers.
