How We Protect Student Data
Last updated: 24th June 2026
YoYo Technologies Ltd
Registered in the United Kingdom
What we collect
YoYo collects only what's needed: a student's first name and first initial of surname, a pseudonymised User_ID, and pronunciation scores. No voice recordings are stored. No emails, photos, or personal profiles are collected from students.
Pronunciation scoring
Pronunciation scoring is handled by SpeechSuper, processing exclusively on UK-based servers (Alibaba Cloud, London). No student data leaves the United Kingdom. Audio is deleted within seconds of scoring — nothing is retained.
Data controllers
YoYo and each partner school act as independent data controllers. We process student data under Legitimate Interests (Article 6(1)(f) UK GDPR), and our full Legitimate Interests Assessment is available to school DPOs on request.
Compliance documentation
Our compliance documentation — including our Privacy Policy, Data Sharing Agreement, Legitimate Interests Assessment, and Technical & Organisational Measures — is available for any school to review.
