1. Data We Collect

We collect your email address and name via Clerk authentication, and your learning progress (which words you've practiced, self-evaluation ratings, and study streaks) stored in Cloudflare D1.

2. How We Use Data

Your data is used solely to provide the SpeechFlow learning experience — tracking your progress, computing streaks, and recommending what to review next. We do not sell or share your data with third parties.

3. Recordings

Recordings you make during practice are processed entirely on your device and are never uploaded or stored on our servers.

4. Cookies

We use a single cookie (lang) to remember your language preference. Clerk may set additional cookies for authentication purposes.
