Security
Prodigy has a history of security issues that they have failed to patch regarding obtaining in-game items, in-game rewards, etc, but not largely around user data. The first Prodigy Math Game exploits were developed in early 2019 by ProdigyMathGameHacking, a GitHub repository dedicated to introducing the security problems that Prodigy has into the public. The exploits did not become well known until early 2020, and the first unsuccessful patch was made in May of 2020  and was unpatched by ProdigyMathGameHacking a few days later. Many patches were made after this, but all were unpatched within a matter of days.
