SalafiMatch

Once the family has run out of names to suggest, the search for a spouse moves to a phone full of swiping apps. SalafiMatch's terms admit only Muslims who follow the Salafi or Ahle Hadith way. Its profiles ask about the scholars someone learns from and whether they pray five times a day.

Someone on the team reads each profile before it goes live, within two to eight hours by the terms. Sisters appear as an illustration from a library, and a brother's photo stays hidden until he shows it to one member. Members must be at least 18, and an optional government ID check adds a trust badge to a profile.

Each sister names her wali, the male guardian who takes part in a Muslim marriage, and his WhatsApp number gets a message when a conversation with her starts. A member who unlocks a sister's contact details sees only the wali's, according to the privacy policy, and never her own number or email.

Two web tools work without an account: a biodata maker that saves a marriage profile as a PDF, and a mahr estimator for the marriage gift. The biodata page says nothing typed into it leaves the device. Inside the app, members can log their Istikhara prayers, the prayer for guidance before a big decision, with notes on each match.
