Prodigy Math is used by 50 million students worldwide. We reviewed its privacy certifications, data collection practices, and the in-app purchase controversy so parents and teachers can make an informed decision.
Prodigy Math is one of the most widely used educational games in North American schools, with over 50 million students and 1.5 million teachers on the platform. When a game is that popular with kids, the first question every parent asks is: is it safe?
The short answer is yes — Prodigy holds some of the strongest privacy certifications in edtech. It has been independently audited and certified by iKeepSafe for COPPA, FERPA, and CSPC (California Student Privacy Certification), meaning a third party has verified its compliance with both federal and state student privacy laws. Prodigy also earned a 92% Common Sense Privacy score, one of the highest among education apps, and holds the 1EdTech TrustEd App Certification.
On the data collection side, Prodigy collects only what it needs to run the game: account info (username, grade level), performance data (questions answered, skills practiced), and standard technical data (IP address, browser type). It does not serve targeted advertising to students, does not sell student data to third parties, and restricts in-game messaging to preset phrases so children cannot share personal information.
The main concern parents raise is not privacy but in-app purchases. While Prodigy is free for teachers, the family version aggressively promotes premium memberships ($59–$180/year) through persistent in-game prompts. In 2021, the Campaign for a Commercial-Free Childhood filed an FTC complaint alleging manipulative upselling tactics. Prodigy remains free to use for math practice, but parents should be aware of the upgrade pressure children will encounter.
We evaluated Prodigy alongside 7 other safe math and education alternatives based on formal privacy certifications, independent audits, data minimization, advertising practices, and in-app purchase transparency.

Yes. Prodigy holds iKeepSafe COPPA, FERPA, and California Student Privacy (CSPC) certifications and earned a 92% Common Sense Privacy score. It does not serve targeted advertising to students, does not sell student data, and limits in-game messaging to preset phrases. However, parents should be aware of persistent prompts for premium membership upgrades within the free version.
Prodigy has been certified by iKeepSafe for COPPA (Children's Online Privacy Protection Act), FERPA (Family Educational Rights and Privacy Act), and CSPC (California Student Privacy Certification). It also holds the 1EdTech TrustEd App Certification and is a member of the Student Data Privacy Consortium (SDPC).
Yes. Prodigy is free for teachers and students to use for math practice, but it offers premium family memberships ranging from $59 to $180 per year. The free version includes persistent prompts encouraging children to ask parents for a membership upgrade. In 2021, child advocacy groups filed an FTC complaint alleging manipulative upselling tactics in the free version.
Prodigy collects account information (username, grade level, school), performance data (questions answered, skills practiced, progress), and technical data (IP address, browser type, device information). It does not collect biometric data, precise location, or photos from students. Student data is used only to provide and improve the service, not for advertising.
Yes. Prodigy Math is completely free for teachers and schools. Teachers can create class accounts, assign curriculum-aligned content, track student progress, and view performance reports at no cost. The premium membership is an optional family purchase that unlocks cosmetic rewards and additional game features.
Yes. Prodigy has been independently audited and certified as compliant with both COPPA and FERPA through iKeepSafe, an FTC-approved COPPA Safe Harbor program. This means a third party has verified that Prodigy meets federal privacy requirements for collecting data from children under 13 and handling student education records.
No. Prodigy does not sell student data to third parties and does not permit any third-party or behaviorally-targeted advertising in its products. Student information is used only to deliver the math game experience, adapt difficulty, and provide progress reports to parents and teachers.
The most common parent concern is the aggressive premium membership marketing within the free version. Child advocacy groups have criticized the disparity between free and premium experiences, noting it can create a "haves and have-nots" dynamic in classrooms. Parents also note the app is better for practice than instruction, offering limited feedback when students answer incorrectly.
Prodigy Math is safe for kids from a privacy standpoint. Its iKeepSafe COPPA, FERPA, and CSPC certifications plus a 92% Common Sense Privacy score place it among the most thoroughly vetted education apps available. Student data is not sold, not used for advertising, and not shared with third parties.
The real concern is the in-app purchase model, not data privacy. Free users encounter frequent upgrade prompts, and the premium experience offers significantly more game features than the free version. Parents who want to avoid purchase pressure entirely should consider Khan Academy Kids or Starfall, both nonprofit and completely free with no upselling.
For schools, Prodigy remains an excellent choice: the teacher version is 100% free, the privacy certifications satisfy most district vetting requirements, and the game-based format keeps students engaged with curriculum-aligned math practice across grades 1–8.
If you need a KidSAFE-certified alternative, IXL and ABCmouse both hold that seal. For a completely free, zero-data-collection option, Starfall collects no personal information from children whatsoever.
