3. Why We Collect This Data

We collect this data solely to provide and improve the Hadaf app:

4. AI Chat Data

When you use the Hadaf AI feature ("Ask Imam / Hadi"), the messages you send are:

  • Transmitted to OpenAI's API in real time to generate a response
  • Stored in your Firebase Firestore account so you can view and continue your chat history at any time

Please do not share sensitive personal information in the AI chat. You can delete all your chats at any time directly from within the app without deleting your account.
