Write to us

The address is contact@bynajm.com. We answer in English or in French.

What to write about

A question about Serenity+, the notebooks or Najm Home.

A printed code that does not lead where it should: tell us the code and the notebook it comes from.

A mistake on this site, a press request, or a partnership with a mosque, a school or a teacher.

Orders and refunds

Products will be sold by the stores that carry them: Amazon for the notebooks and the objects, the App Store and Google Play for the app. For an order, a delivery or a refund, the store’s own customer service is the quickest route. Write to us if it does not settle the matter.

What not to send

Never send a password, a card number or an identity document by email. We will never ask for them.

Who you are writing to
