YazidiBooks is an educational app for exploring Yazidi culture through books, quizzes and vocabulary. This policy describes, in plain language, what information the app collects, how it is used, and the choices you have. The policy is currently available in English only.
Information we collect
Account details: your email address, full name and account role, provided when you register or sign in with Google. Learning activity: reading progress and reading sessions, quiz submissions and scores, vocabulary review progress, points, achievements and reading streaks. Class membership: if you join a class with a class code, your teacher can see your name and your progress on class assignments. Device settings: your language preference and, if you enable notifications, a push notification token. Diagnostics: crash reports and basic technical information (device model, operating system version) used to find and fix bugs.
How we use your information
We use this information only to run the app: to save your reading and learning progress across devices, to power class features between teachers and students, to award points and achievements, to deliver notifications you have enabled, and to keep the app stable. We do not sell your information, show ads, or use your data for marketing.
Where your data is stored
Your data is stored with Supabase on servers located in the European Union (Ireland). A small number of service providers process data on our behalf: Google (sign-in), Expo (push notification delivery) and Sentry (crash reporting). Each provider receives only the minimum needed for its task.
Children's privacy
Student accounts are managed by teachers. For students we collect only what classroom features need: name, learning progress and quiz results. Student data is never used for marketing and is visible only to the student and their teacher.
Data retention and deletion
Your data is kept for as long as your account exists. You can delete your account at any time from Profile, using Delete Account. Deletion is immediate and permanent: your profile, reading progress, quiz submissions, vocabulary progress, points and achievements are all removed.
Your rights
Under the GDPR you have the right to access, correct or delete your personal data, and the right to object to or restrict its processing. Most of this you can do directly in the app; for anything else, contact us using the address below.
Changes to this policy
If this policy changes, we will update the date at the top of this page. For significant changes we will let you know in the app.
