Privacy Policy — Math Battle

Math Battle ("we," "us," or "our") is a math education platform designed for classroom use by teachers and students. This Privacy Policy explains what information we collect, how we use it, and how we protect it. We are committed to handling all user data — especially student data — with care and in compliance with applicable law.

        Plain-language summary: Teachers create accounts and manage their classrooms. Students play games using only a first name — no email or account required. We do not sell any data to anyone. We do not serve ads.

We do not use student data for advertising, behavioral profiling, or any purpose other than providing the educational service to the teacher and their students.

4. Data Sharing & Third Parties

We do not sell, rent, or trade any user data. We share data only with the following service providers as necessary to operate Math Battle:

Google Firebase (Google LLC) — Authentication, real-time database, and hosting. Firebase Privacy
Stripe — Payment processing for teacher subscriptions. Stripe handles all payment card data; we never see or store card numbers. Stripe Privacy
Cloudflare — CDN, DNS, and webhook infrastructure. Cloudflare Privacy

We may disclose information if required by law, court order, or to protect the rights and safety of our users.

5. Student Data & FERPA / COPPA

Math Battle is designed to support compliance with the Family Educational Rights and Privacy Act (FERPA) and the Children's Online Privacy Protection Act (COPPA).

Student data (names, scores, session history) is collected at the direction of and under the control of the subscribing teacher and their institution. The teacher is the responsible party.
We do not knowingly collect personal information directly from children under 13. Students do not create accounts; they participate only within teacher-created sessions.
Student data is used solely to provide the educational service. It is never used for advertising, sold to third parties, or disclosed except as described in this policy.
Teachers are responsible for obtaining any required parental or institutional consent before directing students to use Math Battle.
Upon written request to andy@joinmathbattle.com, we will delete all data associated with a teacher's account, including student records, within 30 days.

6. Google Drive & Google Slides Integration

Math Battle offers an optional feature allowing teachers to connect their Google account to import slides from Google Slides into warmup presentations. This feature uses the read-only Google Drive scope (https://www.googleapis.com/auth/drive.readonly).

What we access: When a teacher connects their Google account, we request permission to read files from their Google Drive — specifically to retrieve Google Slides presentations they choose to import. We access only files the teacher explicitly selects.

What we do with it:

Selected slides are exported as static images (PNG) for display in the Math Battle presenter.
Slide images are used only within the active session and are not permanently stored on our servers.
We do not index, scan, or process any Drive files other than the presentation the teacher selects.
We do not share Google user data with any third party.
Google user data is never used for advertising or to train AI/ML models.

Revoking access: Teachers can disconnect Google Drive at any time from the Teacher Dashboard. Access can also be revoked directly from Google Account permissions. Revoking access does not affect your Math Battle account or subscription.

Our use of Google APIs complies with the Google API Services User Data Policy, including the Limited Use requirements.

7. Data Storage & Security

All data is stored in Google Firebase Realtime Database, which is hosted in the United States. Firebase employs industry-standard security measures including encryption in transit (TLS) and at rest.

While we take reasonable technical and organizational measures to protect your data, no system is completely secure. We cannot guarantee the absolute security of information transmitted over the internet.

8. Data Retention

Teacher accounts: Retained while the account is active. Deleted upon request.
Student session data: Retained as part of the teacher's gradebook for as long as the teacher's account is active.
Google Drive tokens: Stored only while the teacher has connected Google Drive. Deleted immediately upon disconnection or account deletion.
Payment data: Managed by Stripe. We do not store payment card details.

9. Your Rights

Depending on your location, you may have rights to access, correct, or delete your personal data. To exercise any of these rights, contact us at andy@joinmathbattle.com. We will respond within 30 days.

Teachers may delete their account and all associated student data at any time by contacting us. Students do not have accounts; their data can be deleted by requesting it through their teacher or by the teacher contacting us directly.

10. Cookies & Tracking

Math Battle uses only functional cookies and browser storage (localStorage, sessionStorage) necessary for the application to work — for example, storing your active session and class preferences. We do not use advertising cookies, cross-site tracking, or analytics cookies that report to third parties.

11. Changes to This Policy

We may update this Privacy Policy from time to time. When we make material changes, we will update the "Last updated" date at the top of this page. Continued use of Math Battle after changes are posted constitutes acceptance of the revised policy. We encourage teachers to review this page periodically.
