Privacy Policy

1. Introduction

Brainbox Technical Gym ("Brainbox," "we," "our," or "us") provides an interactive, concept-driven learning platform designed to help engineers master deep system engineering, distributed architecture, and problem-solving mechanisms.

We value your trust and are committed to safeguarding your privacy. This Privacy Policy details the types of personal and learning information we collect, how it is processed and secured, and your choices and rights regarding your personal data.

2. Information We Collect

To deliver adaptive technical workouts and track your mastery across topics, we collect the following categories of information:

• Learner Profile & Account Credentials: Your name, phone number, and unique authentication session tokens required to identify your learner account and synchronize progress across devices.
• Learning & Workout Telemetry: Records of your gym interactions, including boxes attempted, evidence selections, diagnostic multiple-choice answers, time per problem, and curriculum progression status.
• Glossary & Knowledge Capture: Technical terms you uncover, open, or add to your personalized glossary during workouts.
• Technical & Device Data: IP address, browser type, operating system, device identifiers, and timestamp logs used for platform diagnostics, rate limiting, and security monitoring.

3. How We Use Your Information

We use the data collected strictly for legitimate educational, operational, and development purposes:

• Generating adaptive problem steps tailored to your current mastery level and specific engineering discipline.
• Preserving your track progress, active sessions, and personal glossary history.
• Monitoring and improving platform stability, backend performance, and pedagogical quality.
• Preventing unauthorized access, service abuse, and fraudulent activity.

4. AI Processing & Third-Party Service Providers

Brainbox leverages state-of-the-art Large Language Models (LLMs) from trusted AI infrastructure providers (such as Anthropic and OpenAI) to dynamically construct technical problem boxes, generate explanations, and deliver contextual feedback.

When you interact with a workout, relevant context (such as the current engineering concept, problem prompt, and prior answers) may be transmitted to these AI APIs to compute the next instructional step.

5. Data Storage, Security & Retention

Your information is stored in secure database environments using encryption in transit (HTTPS/TLS) and encryption at rest. Access tokens stored in your browser are strictly scoped to authenticating your learner sessions.

We retain learner progress and profile data for as long as your account remains active so you can return to past workouts and review your curriculum. If you wish to delete your account and associated history, you may request deletion at any time.

6. Browser Storage & Cookies

Brainbox uses client-side browser storage (such as localStorage) to maintain your login session tokens, UI preferences, and local workout state. We do not employ intrusive third-party cross-site advertising trackers.

7. Learner Rights & Choices

Regardless of your jurisdiction, you have the right to:

• Request a copy of the personal and learning data associated with your phone number.
• Request corrections to any inaccurate profile information.
• Request the permanent deletion of your account, workout history, and glossary items.

8. Updates to this Policy

We may update this Privacy Policy periodically to reflect enhancements to the Gym or regulatory requirements. Any modifications will be posted directly to this page with an updated revision date.
