Privacy Policy

Last updated: November 14, 2026 • Effective immediately

1. Introduction

Welcome to United Crypto Alliance ("UCA", "we", "us", or "our"). We are committed to protecting your personal data, privacy, and sovereignty. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you access or use the United Crypto Alliance mobile application (the "App") and our official website (the "Service").

By downloading, registering for, or using the United Crypto Alliance application, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree with any terms of this policy, please do not use our services.

2. Information We Collect

We collect only the minimal information required to deliver fair, secure, and decentralized mobile mining functionality:

  • Account & Profile Information: When you sign in using Google Sign-In, we collect your basic profile details, including your email address, display name, and unique Google Account identifier.
  • Mining & Session Data: We record timestamp records of your 24-hour mining sessions (start time, expiry time, active status, mining rate, accumulated UCAT coin balances, claim history, and check-in streaks).
  • Referral & Alliance Network Data: To calculate referral bonuses and mutual concurrent mining boosts, we process your unique 6-digit alphanumeric invite code, the invite code you used when joining, and the network list of user identifiers whom you directly referred.
  • Non-Custodial Crypto Wallet Information: Your public wallet address generated inside the app for receiving UCAT and on-chain ecosystem tokens. We never access, store, or transmit your private cryptographic keys to our servers.
  • Device & Technical Identifiers: We collect non-personal device identifiers (e.g., Android Device ID, IP address, device model, operating system version, and app version). This technical data is strictly utilized for anti-fraud detection, Sybil attack prevention, and server synchronization.

3. How We Use Your Information

The information we collect is strictly utilized for the following operational purposes:

  • To initialize, verify, and authenticate your user account securely.
  • To accurately compute your cloud-based mining sessions and instantaneous referral speed multipliers.
  • To attribute mutual mining boosts when you and your direct referrals are actively mining simultaneously.
  • To enforce strict anti-abuse rules, ensuring only real human participants benefit and eliminating emulator farms, botnets, and duplicate accounts.
  • To deliver critical security and feature updates via Firebase Remote Config without requiring unnecessary full-database scans.
  • To respond to your user support inquiries, technical assistance requests, or feedback.

4. Third-Party Services & Infrastructure

We rely on trusted, industry-standard cloud and developer platforms to provide reliable infrastructure:

  • Google Firebase Authentication: For secure, one-tap identity verification without storing passwords on our servers.
  • Google Cloud Firestore & Cloud Functions: For real-time cloud database storage, session verification, and anti-cheat computation.
  • Google Firebase Remote Config: For instantaneous parameter updates and critical update notifications.
  • Google Play Services: For application distribution, licensing, and update distribution.

These third-party providers have their own independent privacy policies governing how they handle data. We do not sell, rent, or trade your personal data to any advertisers or marketing agencies.

5. Data Security

We deploy strict physical, electronic, and managerial safeguards to secure the information we collect. All communications between the mobile application and cloud servers are encrypted using modern Transport Layer Security (TLS 1.3) protocols. Data at rest is encrypted utilizing enterprise-grade AES-256 encryption.

6. Non-Custodial Decentralized Assets

United Crypto Alliance (UCAT) operates on decentralized principles. Users are solely responsible for maintaining the privacy and security of their devices. We will never ask for your private keys, passwords, or recovery seeds.

7. Account Deletion & Your Rights

In compliance with Google Play Store policies and global privacy regulations (including GDPR and CCPA), you have the right to request the complete deletion of your account and associated personal data at any time.

To request permanent deletion of your account, you can contact our data protection team directly by sending an email to support@unitedcryptoalliance.app with the subject line "Account Deletion Request" from the email address linked to your Google Account. Upon verification, your account record and associated data will be permanently wiped from our active databases within 30 business days.

8. Children's Privacy

Our services are not directed to individuals under the age of 13 (or under the age of 16 in certain jurisdictions). We do not knowingly collect personal identifiable information from children. If we discover that a child has provided us with personal data, we will take immediate steps to delete such data from our servers.

9. Changes to This Privacy Policy

We may update our Privacy Policy periodically to reflect changes in our legal obligations, features, or security practices. Any modifications will be posted directly on this page with an updated "Last Updated" date. We encourage you to review this Privacy Policy periodically.
