Privacy Policy

Student Accounts

Student accounts are created and managed through schools. We collect:

• First name and last name
• Username
• Password (securely managed and never stored in plain text)

Student email addresses are not collected or permitted.

Students log in using a username and password provided or managed by their school.

Teacher Accounts

Teacher accounts may optionally include an email address. We collect:

• First name and last name
• Username
• Password
• Optional email address (used for login and account recovery if provided)

Providing an email address is optional for teachers.

Parent Accounts

Parents and guardians can create an account by signing up with an email address or Google account. Parents can create student profiles for their children to access the platform. By creating a student profile, the parent provides direct verifiable parental consent (COPPA) for their child's data to be collected as described in this policy. We collect:

• Parent email address (used for login and account management)
• Parent name (first and last)
• Student profile first names (chosen by the parent)
• Payment-related metadata (Stripe customer ID, subscription status)

Credit card numbers and payment method details are handled entirely by Stripe and never touch Algebro's servers.

Stripe is used only for parent subscription billing. Students, teachers, and school-issued accounts do not interact with Stripe and no payment information is collected from them.

Learning & Progress Data

As students use Algebro, we collect educational data, including:

• Lesson progress and completion
• Quiz scores and attempts
• Practice attempts and results
• Student answers to questions
• Timestamps related to activity completion

This data is used to show students their learning progress, provide teachers insight into class performance, and support instructional feedback.

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 Vercel Analytics and Vercel Speed Insights to monitor platform performance. This may include page views, load times, error rates, and IP addresses.

This data is used solely for reliability, performance monitoring, and improving the educational experience. It does not involve student profiling or advertising. IP addresses are not stored beyond what is necessary for analytics processing.

Cookies

Algebro uses a small number of cookies that are strictly necessary for the platform to function. We do not use advertising cookies, tracking cookies, or third-party marketing cookies.

• Authentication cookies (set by Clerk): used to keep you signed in and maintain your session. These are essential for the platform to work.
• Active profile cookie (algebro-active-profile): used for parent accounts only. When a parent selects a student profile, this cookie stores the selected profile ID so the platform knows which child's data to display. It contains only an internal profile identifier—no names, emails, or other personal information. This cookie is HTTP-only, secure in production, and persists for up to 1 year.

By using Algebro, you consent to the use of these strictly necessary cookies. Because these cookies are required for the platform to operate, they cannot be disabled.

School Official Designation

Algebro operates as a “school official” with a “legitimate educational interest” in student education records under the FERPA school-official exception (34 CFR § 99.31(a)(1)). Algebro performs an institutional service or function for which the school would otherwise use its own employees — specifically, providing standards-aligned math instruction, practice, assessment, and progress reporting. In that role, Algebro:

• Is under the direct control of the school with respect to the use and maintenance of education records;
• Is subject to the requirements of 34 CFR § 99.33(a) governing the use and redisclosure of personally identifiable information from education records; and
• Uses education records only for the purposes authorized by the school or district.

Ownership and Use of Education Records

Education records remain the property of the school or district. Algebro does not sell, rent, or disclose education records to any third party except: (a) to subprocessors contractually bound to protect the data; (b) as directed by the school or district; (c) as required by law; or (d) in the event of a merger, acquisition, or other business transfer, in which case the receiving entity must agree to honor the commitments in this policy. Algebro does not use education records to build advertising profiles or to target advertising.

Parental Access Through the School

Under FERPA, parents and eligible students have the right to inspect and review education records. When Algebro is operating under a school agreement, these rights are exercised through the school or district. Parents should contact their child's school to request access, correction, or deletion of records; the school can then forward the request to Algebro, and we will respond in accordance with our agreement with the school.

School Consent Model

Student accounts are created through schools using class access codes provided by teachers. Under COPPA's school consent exception (16 CFR 312.5(c)(4)), schools may consent to the collection of student information on behalf of parents for educational purposes only. Schools are responsible for providing parents with notice of Algebro's data practices and obtaining any required parental consent before distributing class access codes to students.

Parent Direct Consent Model

For student profiles created by parents through their parent account, the parent provides direct verifiable parental consent by creating the account and student profile. This is not the school consent exception—parents are directly consenting to the collection of their child's educational data. Parents can review, delete, or manage their child's data at any time directly from their parent dashboard.

Parental Rights

Parents and guardians have the right to:

• Review the personal information collected from their child
• Request deletion of their child's personal information
• Refuse further collection or use of their child's information
• Agree to the collection and use of their child's information without consenting to its disclosure to third parties (except as required for the educational service)

To exercise these rights, contact us at jkorwin@algebro.ai or contact your child's school directly.

Data Minimization

We collect only the minimum data required for educational use. We do not collect student email addresses, phone numbers, physical addresses, or other contact information. We do not condition a student's participation on disclosing more personal information than is reasonably necessary.

Deletion on Request

Schools, districts, and parents may request deletion of student data at any time. On receipt of a verified request, Algebro will delete the covered student information within a reasonable time, subject to limited exceptions required by law (for example, records we must retain for tax or audit purposes).

Deletion After Student Unenrollment (School Use)

When Algebro is used under an agreement with a school or district, Algebro will delete a student's covered information within a reasonable time after we are notified that the student is no longer enrolled in or being served by the school, unless the school or parent directs otherwise or retention is required by law. Specific deletion timelines may be set in the district's data privacy agreement with Algebro.

Account Inactivity (Parent Direct Use)

For parent-created student profiles not operating under a school agreement, Algebro will delete or de-identify student data after a prolonged period of account inactivity, or earlier at the parent's request.

Parents and Guardians

Parents and guardians have the right to:

• Review the personal information Algebro has collected from their child
• Receive a copy of that information in a portable format (data export)
• Request correction of inaccurate data
• Request deletion of their child's data
• Refuse further collection or use of their child's information
• Withdraw any consent previously provided under COPPA

Parent-created student profiles can be managed directly from the parent dashboard. Parents can also submit requests by emailing jkorwin@algebro.ai. When Algebro is operating under a school agreement, requests should generally be submitted through the school; the school may forward the request to Algebro.

Students Age 13 and Older

Students who are 13 or older may request to review, correct, or delete their own data by contacting Algebro directly at jkorwin@algebro.ai, or by asking a parent, guardian, or teacher to submit the request on their behalf. When Algebro is used under a school agreement, access requests are generally coordinated through the school under FERPA. Students age 13 or older do not receive an expanded data collection footprint — we still collect the minimum information needed to operate the service.

California Residents (CCPA / CPRA)

California residents may have additional rights under the California Consumer Privacy Act (CCPA), as amended by the California Privacy Rights Act (CPRA), including the rights to know, delete, correct, and opt out of the “sale” or “sharing” of personal information. Algebro does not sell or share personal information as those terms are defined under CCPA/CPRA. California residents may submit requests at jkorwin@algebro.ai.

No Discrimination

Algebro will not discriminate against any user for exercising their privacy rights — for example, by denying service or charging a different price — except where the exercise of a right makes it impossible for us to provide the service (for example, if all student data is deleted, practice and progress tracking can no longer function).
