Your email address and, if you choose to add it, your phone number. Account details you provide (name, BAC stream, preferred language, study preferences). Study activity you generate on Nadjah: lesson progress, quiz results, flashcard reviews, and study-plan tasks. Basic product analytics events (e.g. signup, login, lesson completed) tied to your account, never sold or shared with advertisers.
We don't ask for more than we need to run the product. No payment card details are ever stored by Nadjah directly — payments are processed by Chargily, our Algerian payment provider, and we only store the resulting subscription status.
To run your account, show your personalized study plan and progress, generate AI study content, and improve the product. We never expose your study progress or quiz results publicly, and other students can never see your data.
We use Google (sign-in), Resend (email delivery), an SMS provider (phone verification), Replicate (AI content generation), the YouTube Data API (lesson videos), and Chargily (payments). Each only receives the minimum data needed to perform its function.
Your account and study data is stored on servers located in the United States (our database provider, Neon, runs on AWS us-east-2; our hosting provider, Vercel, runs on AWS infrastructure). By creating an account, you consent to this transfer and processing of your data outside Algeria. We only use providers who contractually commit to data security and breach notification, and we never sell or share your data with advertisers.
You can delete your account at any time from Profile → Security. This permanently removes your account and all associated study data. You can also sign out of all devices from the same page.
