Payments
Payments are processed by Google Play, the Apple App Store or Stripe. Zebrovia never receives or stores your card details; we only store the purchase status (e.g. "Premium active until…").
Purpose and legal basis
Providing the service you signed up for (GDPR art. 6.1.b); legal invoicing duties (art. 6.1.c); news emails only with your consent (art. 6.1.a), which you can withdraw at any time.
Daily AI class
If you use the voice teacher, your voice is streamed live to xAI to produce the answer. We do not keep recordings; we only count the minutes used.
AI features
If you use the AI tutor (chat), the weekly-exam guidance or the voice teacher, the text or voice needed is sent to xAI to produce the answer; we only log the cost and date of each use to enforce spending limits.
Support staff access
Authorised Zebrovia support/admin staff can access your account data (name, e-mail, licence, purchases and access status, progress, results and AI usage) only to help you, manage payments and access, prevent fraud and run the service. This access requires a verified sign-in, is limited to admin accounts, and access changes are logged.
