Data Protection Impact Assessment

Template — Version 1.0 — May 2026

This pre-filled DPIA template helps your school's DPO assess Mustard Investments before deployment. Customise the school-specific sections and file with your records.

1. Project description

System name: Mustard Investments — Financial Education Platform
Purpose: To provide age-appropriate financial education to students aged 11–18 through interactive lessons, quizzes, paper trading, and gamified learning pathways.
Data controller: [Your school name — to be completed by school]
Data processor: Mustard Investments Ltd
DPO contact: dpo@mustardinvestments.com

2. Necessity and proportionality

Lawful basis: Legitimate interests of the school in delivering financial education (Article 6(1)(f) UK GDPR). For under-13s, parental consent (Article 8 UK GDPR / ICO AADC).
Data minimisation: Only data strictly necessary for the educational service is collected. No home addresses, photographs, biometric data, or special category data.
Alternatives considered: Offline alternatives (worksheets, textbooks) do not provide personalised learning, progress tracking, or the engagement benefits of gamification. The data processing is proportionate to the educational benefit.

3. Consultation

[To be completed by school] — Record any consultation with students, parents, staff, governors, or the ICO.

4. Risk assessment

Pre-filled with platform-specific risks. Add school-specific risks (e.g. shared devices, BYOD policies) as needed.
