D1 AI (“we,” “us,” or “our”) operates the D1 AI mobile application (the “App”). This Privacy Policy explains how we collect, use, and protect information when you use the App.
This Privacy Policy applies to D1 AI, developed by Molly Webb.
By using the App, you agree to the data practices described below.
We collect only the minimum information necessary to provide athletic form analysis and improve app performance.
Training Videos
When you choose to record or upload a training video, the App uses that video to provide AI-powered athletic form feedback.
Videos may be securely transmitted to trusted processing services for analysis. Uploaded videos are discarded immediately after analysis and are not permanently stored by D1 AI.
Sports Preferences
We collect the sport or training options you select to personalize your experience.
Support Contact Information
If you email support, we may collect your email address so we can respond.
Device and Diagnostic Information
We may collect basic device details such as device model, operating system version, and crash reports to help maintain app stability.
Anonymous Usage Analytics
We may collect anonymized information such as feature usage and performance data to improve the App. This data is not used to identify you.
If you choose to purchase a premium subscription, Apple processes all payments securely through your Apple ID. We do not receive or store your credit card or billing information.
We may receive limited purchase and subscription information from Apple and our subscription service provider, such as:
• Subscription status (active, expired, canceled)
• Transaction and receipt identifiers
• Subscription plan type (monthly or yearly)
• Purchase and renewal dates
This information is used only to provide premium features, restore purchases, and manage your subscription.
We use collected information only to:
• Analyze training videos and provide athletic feedback
• Generate personalized workout recommendations
• Improve app features and performance
• Fix bugs and maintain reliability
• Provide customer support
• Verify subscription status and provide premium features
We do not sell or rent your personal information.
Video Data
Videos are processed only to generate feedback and are discarded after analysis. D1 AI does not retain uploaded video files.
Analysis Results
Feedback results may be stored locally on your device. You may delete this information at any time.
Analytics and Diagnostic Data
Anonymous analytics and crash data may be retained for up to 24 months to improve the App.
D1 AI offers optional auto-renewing monthly and yearly subscriptions that unlock premium features.
Payments are processed by Apple through the App Store. D1 AI does not collect or store payment card information.
When you purchase a subscription:
• Apple shares limited transaction data with us
• We use this data to unlock premium features
• We use trusted services such as RevenueCat to validate receipts and manage subscription status
Subscription data is used solely to:
• Activate and maintain premium access
• Restore purchases across devices
• Provide customer support
• Prevent fraud and abuse
Subscriptions automatically renew unless canceled at least 24 hours before the end of the billing period. You can manage or cancel subscriptions in your Apple ID account settings.
To provide core functionality, D1 AI may use trusted third-party providers, including:
• OpenAI – AI video analysis
• RevenueCat – subscription management and receipt validation
• Supabase – secure backend infrastructure
• Analytics and crash-reporting tools
These providers may process information only to provide services for the App and are required to protect user data.
Uploaded videos are used only to generate athletic feedback and are not used to train third-party AI models.
We take reasonable steps to protect your information, including:
• Encryption of data transmissions (TLS/SSL)
• Secure processing infrastructure
• Limited access controls
No method of transmission is completely secure, but we work to safeguard your data.
