  • International Data Protection Standards including global data subject rights and privacy-by-design engineering principles.

  • Practice response audio recordings for instructor verification.
  • Zero voice data monetization or behavioral ad profiling.

44. Federated Social Login (Google / Facebook) & Single Email Restriction

VoiceSkillUp supports federated single sign-on via Google OAuth 2.0 and Facebook Login. When utilizing social authentication:

  • Minimal Scopes: We strictly request read-only access to your public profile name, verified email address, profile picture, and unique provider subject identifier.
  • Zero Social Graph Access: We never request access to your friends lists, social feeds, private messages, or contacts.
  • Single Email Architecture: One email address cannot be registered across multiple disconnected accounts. Users with an existing local account linking a social login maintain a unified profile.
  • Role Switching: Apprentices can seamlessly transition to Instructor mode and vice-versa within their dashboard without duplicate account creation.

55. Pedagogical Voice AI & N-ATLaS Audio Safeguards

Voice is our primary pedagogical interface for vocational education in Hausa and English. Audio streams captured for speech-to-text (STT) and N-ATLaS AI tutoring are protected under strict commitments:

Voice Data Sovereignty Commitments:
  • No Commercial Monetization: Spoken audio recordings are NEVER sold, rented, leased, or licensed to third-party data brokers.
  • No Cross-Site Behavioral Tracking: Voice inputs are strictly bound to educational evaluation, trade safety instructions, and skill mastery.
  • Explicit Microphone Consent: Audio capture only activates upon explicit user initiation (tapping the microphone button).
  • Pseudonymized Transcripts: Training corpus logs decouple personal user identifiers from audio text transcripts.

66. Lawful Bases for Processing under NDPA 2023

  • Performance of Contract: Delivering vocational LMS features, grading voice assignments, and issuing verified trade certificates.
  • Explicit User Consent: Capturing microphone audio, accessing local device storage, and sending educational updates.
  • Legitimate Interests: Protecting platform safety, preventing hazardous electrical guidance errors, and mitigating credential fraud.
  • Legal Obligation: Complying with regulatory reporting, tax laws, and lawful law enforcement requests within Nigeria and the African Union.
