Report: 96% of School Apps Send Kids’ Personal Data to Potentially Harmful Third Parties

Internet Safety Labs Randomly Tested Apps Used in Every State by Almost Half a Million Students

In a new K–12 ed tech safety benchmark report, “School Mobile Apps Student Data Sharing Behavior,” Internet Safety Labs finds that 96% of all apps used in schools share children’s personal information with third parties without the knowledge or consent of the users or the schools.

The report, the first of four in the works, is based on research by ISL first published in May 2021. The data was gathered from a random sample of 13 schools in each of the 50 states and the District of Columbia for a total of 663 schools and 455,882 students.

According to ISL, 78% of the student data shared with third parties was shared with advertising and data analytics entities.

ISL tested 1,357 apps recommended or required by schools. Applying four safety score outcomes (high risk, some risk, do not use, and unable to test), it found that 78% of apps were scored “do not use” and 18% were “high risk.”

Key Findings Concerning Student Privacy and Safety

  • 74.9% of the apps tested were scored “very high risk” for having SDK components that were “likely to share data with high-risk entities,” ISL said.
  • Location information was accessed by 79% of the apps, based on permission analysis.
  • 52% of the apps tested accessed the students’ calendar and contacts information.
  • 72% of K–12 schools’ “top 25 recommended apps” and 56% of the top 25 mandatory apps were scored “do not use” by ISL.
  • 28% of apps tested were not specifically made for education, the report noted, “such as The New York Times, YouTube, or Spotify, effectively providing no limits or guardrails for children.”

The report also details child safety concerns about Google, noting that Google “dominates K–12 ed tech as the prime supplier of both hardware and software.” According to the report, 75% of schools provided Google Chromebooks or tablets to students, with Apple providing 34%. Of the apps sending out data, 68% of it went to Google and 36% to Apple.

ISL recommended that schools and local education agencies become more cautious about adopting new ed tech — adding that schools need more support and financial resources to understand and implement it.

The organization noted it had seen “no evidence that ed tech developers prioritize safety” and recommended that the industry “needs to join the conversation on software product safety for students.” The report said that changes are not out of reach because only “a handful of key developers provide most of these apps to schools across the US… [t]hey should be able to readily make the necessary safety improvements.”
