1. Introduction: Your Privacy is Foundational

Welcome to Banza ("we," "our," "us"). At Banza, your privacy isn't just a feature; it's the foundation of everything we do. We are committed to empowering you to securely control, integrate, and benefit from your personal digital footprint. This Privacy Policy outlines how we handle your information with transparency and respect, leveraging advanced privacy-enhancing technologies like zero-knowledge proofs (including zkTLS for data attestation) and secure computation environments.

This policy explains how information is managed when you use our mobile application ("App") and associated services. By using our App, you agree to the practices described in this policy.

2. Information Under Your Control

Banza is designed so that you, the user, are in control of your data. We facilitate the secure integration and management of your information, rather than collecting it directly without your explicit action.

• User-Attested Data: Banza enables you to self-attest data from various third-party applications and sources you use (e.g., media consumption activity, wellness and fitness data, purchase histories, social interactions). This process uses technologies like zkTLS (Zero-Knowledge Transport Layer Security) to allow you to prove facts about your data from these sources in a private, encrypted, and verifiable manner, without revealing the underlying raw data to us or unnecessary parties.
• Decentralized Storage: All attested data and associated cryptographic proofs are stored in decentralized data vaults that are under your direct control.
• Profile Information: Basic information you provide for account setup and profile personalization (e.g., username, profile picture if chosen).
• Usage Data (Anonymized): We collect anonymized or aggregated data about how you interact with the Banza App itself (e.g., feature usage frequency, performance metrics) to improve the service. This does not include the content of your attested data.
• Contact List (Optional): We may request access to your device's contact list only if you choose to use specific features, such as our referral program. We will clearly ask for your permission before accessing your contacts.

We Do Not Collect: Banza is architected to respect your privacy boundaries. We do not collect, access, or store:

• Login credentials (usernames, passwords) for your third-party accounts.

• The content of your private messages or emails.

• Raw, detailed browsing history or precise, continuous location data.

3. How We Use Information (With Your Control)

Our use of information is centered around providing value back to you while rigorously protecting your privacy. We primarily use processed or anonymized data derived from your self-attested information:

• Powering Your AI Twin ("Maai"): Anonymized and securely processed data helps build and refine your personalized AI assistant, "Maai," enabling it to provide relevant insights and proactive assistance based on your integrated digital footprint.
• Personalized Insights, Recommendations & Rewards: We use patterns derived from your controlled data to power our universal recommendation engine and offer personalized insights, suggestions, and potential rewards (e.g., through our tokenized system) based on your preferences and activities, all while preserving privacy.
• Improving AI Models and Services: Aggregated and anonymized data helps us train and improve our core AI models (including the Super Agent and specialized sub-agents) and enhance the features, usability, and performance of the Banza App. This may include generating high-quality synthetic data for developers using our platform, derived from anonymized patterns.
