Proof Privacy Policy

Last updated: August 2026

Proof ("we," "us," "our") respects your privacy. This policy explains what data we collect, how we use it, and your rights.

Information We Collect

• Account information: email address and authentication data when you sign up
• Photos: images you take to verify habit completion
• Usage data: habits created, streaks, app activity, and interactions with friends/social features
• Device information: basic technical data needed for app functionality

How We Use Your Data

• To verify habit completion using AI-based photo analysis
• To maintain your account, streaks, and progress history
• To enable optional social features (sharing proofs with friends,)
• To improve app performance and features

Photo Processing Photos you submit for habit verification are processed using AI vision technology to confirm they match the habit being logged. Photos may be stored to maintain your habit history and, if you choose to share them, shown to friends within the app. Photos are not sold or shared with third parties for advertising purposes.

Data Storage Your data is stored securely using industry-standard cloud infrastructure (Supabase). We take reasonable measures to protect your information from unauthorized access.

Third-Party Services We use third-party services to operate Proof, including:

• Supabase (database and authentication)
• OpenAI (photo verification processing)

These providers process data solely to support Proof's functionality and are bound by their own privacy and security standards.

Your Rights You may request access to, correction of, or deletion of your personal data at any time by contacting us at [email protected]. Deleting your account will remove your habit data, photos, and associated account information.
