Subprocessors

Third-party services that process data on behalf of SpellingJoy.

Last updated: November 8, 2026

SpellingJoy uses the following subprocessors. The first group serves the spelling practice service at spellingjoy.com, which is covered by our Student Data Privacy Agreement; each of those is bound by a Data Processing Agreement requiring data protections no less stringent than our own commitments under that agreement. The second group serves SpellingJoy ELA, our separate homeschool product, which is not part of any district agreement and processes no classroom or roster data.
