Math Fact Expedition is operated by Advant Education LLC, a New Mexico limited liability company ("Advant Education," "we," "us," or "our"). This Privacy Policy explains what information we collect through the Math Fact Expedition website (mathfactexpedition.com) and web application (the "Service"), how we use it, and the choices you have.
We built Math Fact Expedition for children in grades 1–8, which means we take children's privacy seriously. This policy is written to comply with the Children's Online Privacy Protection Act (COPPA), the Family Educational Rights and Privacy Act (FERPA), and applicable state student privacy laws. We have tried to write it in plain language. If anything is unclear, email us at hello@mathfactexpedition.com.
This policy applies to:
Math Fact Expedition is intended for use in the United States. If you use the Service from outside the U.S., your information will be processed in the U.S.
When you create an account or purchase a plan, we collect:
We use this information to create and secure your account, process your purchase, deliver the Service, send you progress reports and service notices, respond to your questions, and (if you opt in) send you product updates.
Students access the Service only through a profile that an Adult has created. We collect only the following from or about a Student:
We do not collect from Students: last names, email addresses, phone numbers, home addresses, photos, video, audio, precise geolocation, biometric identifiers, government identifiers, social media handles, or any information about other people. The Service has no chat, messaging, social, or public-posting features. Students cannot communicate with other users through the Service.
We do not use persistent identifiers from Students for behavioral advertising, cross-site tracking, or building marketing profiles. Any persistent identifiers (such as a session token) are used solely to support the internal operations of the Service — specifically, to keep the Student signed in during a practice session, to save their progress, and to maintain security.
Math Fact Expedition is designed for children, including children under 13. We comply with COPPA as follows.
Parent and guardian accounts. When a parent or guardian creates a Family account and adds a student profile, the parent is providing verifiable consent to the collection and use of that child's information as described in this policy. We confirm the parent's email address before the account becomes active, and the parent holds the credentials that control the child's profile.
Educator accounts. When a teacher or school creates a Classroom account and adds student profiles, the school is providing consent on behalf of parents for educational purposes, consistent with Federal Trade Commission guidance permitting schools to authorize the collection of student information for the use and benefit of the school. By creating student profiles, the educator represents that they have the authority to do so under their school's or district's policies.
An Adult may, at any time:
Parents whose child uses the Service through a school account should contact the school first; the school controls the account. We will also honor requests directly from a parent once we've confirmed the child's identity with the school.
We do not disclose Students' personal information to any third party for that third party's own use. The only parties that ever process Student data are the service providers in Section 6, who act on our instructions and are contractually prohibited from using the data for anything else. Because we make no other disclosures, no separate consent for third-party disclosure is required or requested.
To make sign-in easy for young children, Students sign in by entering a group code (one code per family or classroom) and then tapping their own first name and avatar from a list. Anyone who enters a valid group code will see the list of first names and avatars in that group. No other information is shown — not last names, not progress, not PINs.
This is the same approach used by widely adopted classroom tools. To reduce risk:
We use the following providers to run the Service. Each processes data only on our behalf and under a contract that restricts its use to providing the service to us.
| Provider | What it does | Data it handles |
|---|---|---|
| Supabase, Inc. | Database hosting and account authentication | All account data, student profiles, and practice data. Stored in the United States. |
| Vercel, Inc. | Website and application hosting; performance monitoring | Technical request data and anonymized page-performance metrics (Vercel Speed Insights). No student names or progress data are sent to Speed Insights. |
| Stripe, Inc. | Payment processing | Adult name, email, billing address, and payment card details. Stripe's own privacy policy governs card data. |
| Kit (ConvertKit) | Email delivery to Adults | Adult name and email address, plan type, and email engagement (opens/clicks). Kit never receives any Student information. |
We may add or replace providers as the Service evolves. If we do, we will update this table. If any change would involve disclosing Students' personal information to a new category of recipient, we will obtain fresh consent before doing so.
We do not sell personal information. We do not share personal information with data brokers, advertisers, or analytics companies for their own purposes. We do not use third-party advertising or tracking technologies anywhere in the Service.
We may disclose information if required by law, subpoena, or court order; to protect the rights, property, or safety of users or the public; or in connection with a merger, acquisition, or sale of assets, in which case the successor will be bound by this policy for data already collected.
When an educator or school uses Math Fact Expedition, we act as a "school official" with a legitimate educational interest under FERPA, and as a service provider / operator under applicable state student privacy laws. In that role:
Schools and districts that require a signed Data Privacy Agreement may contact us at hello@mathfactexpedition.com. We offer the Student Data Privacy Consortium's National Data Privacy Agreement (NDPA) as our standard form, and we will honor an existing NDPA on file in your state's SDPC alliance where applicable.
Under COPPA we are required to publish how long we keep children's personal information. Here is our schedule.
| Data | Retained until | Then |
|---|---|---|
| Student profile and practice data (active account) | While the Adult's account is active and the profile has not been deleted | Deleted on request or on account closure |
| Student profile and practice data (Adult deletes the profile) | Immediately removed from the live database | Purged from encrypted backups within 30 days |
| Student profile and practice data (Adult account inactive) | 24 months after the Adult's last sign-in, after two email reminders | Deleted, then purged from backups within 30 days |
| Student profile and practice data (subscription expired, not renewed) | 90 days after expiration, so a family can renew without losing progress | Deleted, then purged from backups within 30 days |
| Adult account information | While the account is active, plus 24 months of inactivity | Deleted, except records we must keep for tax, accounting, or legal purposes (Section 8, below) |
| Purchase and payment records | 7 years, as required for tax and accounting | Deleted |
| Sign-in and security logs | 90 days | Deleted |
| Support emails | 2 years | Deleted |
We retain children's personal information only as long as reasonably necessary to fulfill the purpose for which it was collected. We do not keep it indefinitely.
To delete a profile or account yourself, use the Adult dashboard. To request deletion by email, write to hello@mathfactexpedition.com from the email address on the account.
We maintain a written information security program appropriate to the sensitivity of the data we hold and the size of our operation. It includes:
No system is perfectly secure. If we learn of a breach affecting personal information, we will notify affected Adults (and affected schools) by email without unreasonable delay and as required by applicable law, and we will describe what happened and what we're doing about it.
Access, correction, and deletion. Adults can manage their own information and their Students' information from the dashboard, or by emailing us. We respond to verified requests within 30 days.
Email preferences. We send three kinds of email: (1) transactional messages you can't opt out of while you have an account (receipts, password resets, security notices); (2) progress reports about your Students, which you can turn off in the dashboard; and (3) product updates and tips, which you can unsubscribe from using the link in any such email. We never email Students.
State privacy rights. Residents of certain states (including California, Colorado, Connecticut, Virginia, and others) have rights to access, delete, correct, and port their personal information, and to opt out of sales or targeted advertising. We do not sell personal information or engage in targeted advertising, so there is nothing to opt out of. We honor access, deletion, correction, and portability requests from residents of any state, whether or not a specific law requires us to. We will not discriminate against you for exercising these rights.
California minors. If you are a California resident under 18 and have posted content on the Service, you may request its removal. The Service currently has no user-posting features, but this right applies if that changes.
We use only the technologies needed to make the Service work:
We do not use advertising cookies, social media pixels, or third-party analytics trackers. Because we do not track users across other websites, we do not respond differently to "Do Not Track" signals — there is no cross-site tracking to turn off.
If we make material changes — especially any change to how we collect, use, or disclose Students' information — we will notify Adults by email before the change takes effect and, where COPPA requires it, obtain new consent. Minor clarifications may be posted without notice. The "Last updated" date at the top tells you when this policy last changed.
