  • Privacy policies do indicate a version or effective date.
  • Unclear whether data are sold or rented to third parties.
  • Data are not shared for advertising or marketing.
  • Behavioral or contextual advertising is not displayed.
  • Unclear whether this product allows data collection by third-party advertising or tracking services.
  • Unclear whether this product uses data to track and target advertisements on other third-party websites or services.
  • Unclear whether this product allows third parties to use data to create ad profiles, data enhancement, and/or targeted advertisements.
The criteria for "Use with Caution" are narrowly focused around data uses related to creating profiles that aren't related to any educational purpose, and using data to target ads. We include both first party (ie, the vendor that builds the service) and third party (any company given access by the vendor) data use. It's worth highlighting that using data to profile students violates multiple state laws, and in some cases also violates federal law.

A service can be designated "Use with Caution" for either a lack of transparency around data use -- which creates the potential for profiling and behavioral targeting -- or for clearly stating that they use data to target advertisements and/or create profiles. As with any application being considered for use within schools, school and/or district staff should review the privacy policies and terms of service to ensure that they meet the legal and practical requirements of their state laws and school policies.

As with the "Not Recommended" criteria, a "Use with Caution" designation is NOT a sign that a vendor is necessarily doing anything unethical or illegal. It is a sign that, based on publicly available policies,  we do not have adequate guarantees that data will not be used by first or third parties to create non-educational profiles or to target behavioral ads.

About Privacy Evaluations

The privacy evaluations have been designed with the help and support of a consortium of schools and districts across the United States. These evaluations are designed to streamline making an informed decision about the potential privacy implications of educational technology used to support teaching and learning.

Our core evaluation criteria are freely available and will remain freely available. People are encouraged to read the questions we use and the information security primer we released. Vendors are encouraged to use our questions and the information security primer to self-evaluate. You can also learn more about our evaluation process.
