How privacy works
Your Hajj stays yours
Hajj Buzz keeps three things apart: your conversations, your private details, and your organizers' space. Tap each one to see what it holds.
Locked on your phone
Your private details
Your name, Hajj type, care needs and any contributions are locked on your phone, and can only be opened by your own group organizers.
Your private, secure guide
End-to-end confidential
Direct connection to your group organizers
Who can see what
The payment service knows an amount was paid, but never who paid it or what it was for.
