Roll AI ("we", "us", "our") is a BJJ training log and AI video analysis app. This policy explains what information we collect, how we use it, and your rights over it.

1. Information we collect

Account information

When you create an account we collect your email address. If you sign in with Apple, we receive a name and an anonymised relay email from Apple.

Profile information

Information you voluntarily enter in the app: belt rank, stripes, training frequency, gym name, weight, height, date of birth, training style preferences, and goals.

Training data

Roll logs you create: date, duration, notes, energy levels, techniques, outcomes, and journal entries. This data is stored on your account and never shared with third parties.

Video clips

When you use the AI video analysis feature, your video clip is transmitted securely to our servers and immediately forwarded to Google's Gemini AI service for analysis.

Your video is permanently deleted from our servers within seconds of the analysis completing. We do not store, retain, or review your video clips.

Usage data
