  • Demo usage does not earn BroCoins
  • Demo activity is not associated with any student account

Virtual Currency (BroCoins)

Students may earn BroCoins by completing lessons, quizzes, and practice sessions. We track BroCoin balances, earning events, and spending on virtual items (themes and cosmetic features).

BroCoins:

  • Have no real-world monetary value
  • Cannot be purchased or exchanged for money
  • Do not affect academic grades or evaluations

Automatically Collected Data

We use basic infrastructure analytics to monitor platform performance. This includes page views, load times, and error rates.

These analytics are used solely for reliability and performance monitoring and do not involve student tracking or profiling.

How We Use Data

We use collected data to:

  • Operate and maintain the Algebro platform
  • Provide educational functionality
  • Track and display student progress
  • Give teachers insight into student learning
  • Power AI-assisted instructional feedback
  • Maintain platform security

We do not use student data for advertising, marketing, profiling, or non-educational purposes.

AI Features

Algebro uses AI (powered by OpenAI) to assist students through the Bro learning guide and to generate feedback on quiz answers.

What is sent to AI services:

  • Math problems
  • Student answers
  • Lesson context

What is NOT sent:

  • Student names
  • Usernames
  • Email addresses
  • Any personally identifiable information

AI interactions are processed in real time and stored only temporarily in the user's browser session. They are not saved to Algebro's database and are not retained as educational records.

  • Input validation on user-submitted data

Children's Privacy

Algebro is designed for middle school students, including children under 13. Student accounts are created through schools using class access codes. This operates under the school consent model, where schools authorize the use of educational technology on behalf of students.

We collect only the minimum data required for educational use and do not collect student email addresses or contact information.

Data Retention & Deletion

  • Request deletion of data
  • Withdraw consent for platform use

Requests may be submitted through the school or by contacting us directly.
