Privacy Policy

Effective as of 2026-09-25

This privacy policy applies to the Rack Star (also distributed as Rack Star Training) app for mobile devices and web browsers, together with any related services operated by Shynnergy, LLC (collectively, the "Application"). Shynnergy, LLC is hereby referred to as the "Service Provider".

Information Collection and Use

The Application collects information when you download and use it. This information may include details such as:

  • Your device's Internet Protocol (IP) address
  • Your device type, operating system version, and system locale
  • The screens and drill features you interact with, including the dates, times, and duration of your practice sessions
  • Training progress metrics such as drill completion counts, speed, accuracy statistics, and practice streaks

Account Information & Authentication

When you create an account or sign in to sync your training progress across devices (for example, via Google Sign-In), we collect your name, email address, unique authentication identifier, and avatar URL provided by the identity provider. This information is stored securely on our backend servers solely to manage your account, authenticate your sessions, and synchronize your practice data and drill history.

Profile Photos & Camera / Photo Library Access

If you choose to upload or customize a profile picture within the Application, we may request permission to access your device camera or photo library. We store and process your selected photo solely to display your avatar in the app interface. We do not use your photos for facial recognition or biometric identification, nor do we sell or disclose them to third-party advertising networks.

Cookies and Tracking Technologies

The Application or its third-party SDKs may utilize cookies, tokens, device identifiers, and similar technologies to support authentication, offline caching, and feature telemetry. Where required by applicable law, the Service Provider will seek your prior consent for non-essential tracking.

Your Rights

You may request access to, correction of, or deletion of your personal data held by the Service Provider. To exercise these rights, or to withdraw consent where processing is based on consent, contact the Service Provider at shynnergy@gmail.com.

Your California Privacy Rights (CCPA/CPRA)

If you are a California resident, you have the right to know what personal information is collected, the right to request deletion of personal information, the right to opt out of any sale or sharing of personal information, and the right to non-discrimination for exercising these rights. The Service Provider does not sell personal information. To exercise your CCPA/CPRA rights, contact the Service Provider at shynnergy@gmail.com.

Third-Party Services

Only aggregated, anonymized data is periodically transmitted to external services to aid the Service Provider in improving the Application. Below are the third-party service providers utilized by the Application for authentication, analytics, or store fulfillment:

The Service Provider may disclose collected information:

  • as required by law, such as to comply with a subpoena or court order;
  • when believed in good faith that disclosure is necessary to protect rights, protect user safety, investigate fraud, or respond to valid government inquiries;
  • with trusted infrastructure vendors who perform hosting and database services on behalf of the Service Provider under strict confidentiality obligations.

Opt-Out Rights & Account Deletion

You can stop all data collection by the Application by uninstalling it from your device. You may also request complete deletion of your account and associated training records at any time by contacting shynnergy@gmail.com. We will process your deletion request promptly in accordance with applicable laws.

Data Retention Policy

The Service Provider retains personal information as long as your account remains active or as needed to provide you with training services:

  • User Profile and Drill History: Retained during active use plus 12 months following account inactivity, unless earlier deletion is requested
  • Server Logs & Operational Telemetry: Retained for up to 90 days for troubleshooting and security auditing
  • Aggregated, Anonymized Data: Retained indefinitely for statistical analysis and machine learning evaluation

Children's Privacy

The Application is intended for general audiences and is not directed to children under 13 years of age. The Service Provider does not knowingly collect personally identifiable information from children under 13. If you become aware that a child has provided us with personal data, please contact shynnergy@gmail.com so we can immediately delete such data.

Security

We provide administrative, technical, and physical safeguards—including encrypted HTTPS/TLS communications, authenticated API tokens, and restricted database access—to protect your personal information from unauthorized access, alteration, or disclosure.

Changes to this Privacy Policy

The Service Provider may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated effective date. Continued use of the Application after changes are published constitutes acceptance of the revised policy.
