Hanlexon helps students learn Mandarin Chinese. We take the privacy of your students seriously. This page explains how we protect student data, what we commit to, and what your district needs for procurement — all self-serve, no NDA required.
Hanlexon signs the SDPC National Data Privacy Agreement state-by-state on request from any LEA.
We comply with FERPA, COPPA, SOPPA, UK GDPR, and the Australian Privacy Principles — full details in our Privacy Policy §11 and Terms of Service §7.
Purpose-driven. AI is invisible infrastructure that helps a student learn Mandarin — not a feature for its own sake.
Privacy-focused. Student-submitted content (writing, voice recordings, chat) is never used to train AI models. We configure commercial-API settings to disable training where supported.
Transparent. The human teacher remains in control. AI-generated content is labeled as such where relevant.
Reliable. Fair-use limits prevent abuse and maintain quality for all students.
Configurable. Schools can opt out of AI features per class or globally.
We publish our privacy and contractual artifacts so your district's procurement team can self-serve. No NDA, no signup, no email capture.
For UK GDPR, EU GDPR, AU APP, and any institution outside US K-12. Includes Article 28 clauses, Standard Contractual Clauses, and UK IDTA.
View / print HTML versionFor US K-12 districts. Hanlexon signs the SDPC NDPA v2.2 STANDARD with Exhibit E (General Offer of Privacy Terms) — one signed agreement covers all 50 states. Other districts in any state countersign Exhibit E to adopt the same terms; their state-specific Exhibit G is auto-attached by SDPC.
