The Rosary is a private devotion and it is not required or mandated in any way by the church.
The only exception would be if you joined an order or confraternity which required you to pray it, but that would be explained to you before hand.
The way the Church has proposed the rosary is arguably exceptional.
“The Rosary is a powerful weapon to put the demons to flight and to keep oneself from sin…If you desire peace in your hearts, in your homes, and in your country, assemble each evening to recite the Rosary. Let not even one day pass without saying it, no matter how burdened you may be with many cares and labors.” – Pope Pius XI
The Rosary is the most excellent form of prayer and the most efficacious means of attaining eternal life. It is the remedy for all our evils, the root of all our blessings. There is no more excellent way of praying.” Pope Leo XIII
The Rosary is the most beautiful and the most rich in graces of all prayers; it is the prayer that touches most the Heart of the Mother of God…and if you wish peace to reign in your homes, recite the family Rosary.~Pope Saint Pius X
There is no surer means of calling down God’s blessings upon the family… than the daily recitation of the Rosary.~Pope Pius XII
"Since, therefore, it is clearly evident that this form of prayer is particularly pleasing to the Blessed Virgin, and that it is especially suitable as a means of defence for the Church and all Christians, it is in no way wonderful that several others of Our Predecessors have made it their aim to favour and increase its spread by their high recommendations. Thus Urban IV, testified that “every day the Rosary obtained fresh boon for Christianity.” Sixtus IV declared that this method of prayer “redounded to the honour of God and the Blessed Virgin, and was well suited to obviate impending dangers;” Leo X that “it was instituted to oppose pernicious heresiarchs and heresies;” while Julius III called it “the glory of the Church.” So also St. Pius V., that “with the spread of this devotion the meditations of the faithful have begun to be more inflamed, their prayers more fervent, and they have suddenly become different men; the darkness of heresy has been dissipated, and the light of Catholic faith has broken forth again.” Lastly Gregory XIII in his turn pronounced that “the Rosary had been instituted by St. Dominic to appease the anger of God and to implore the intercession of the Blessed Virgin Mary.” (Supremi Apostolatus Officio, Pope Leo XIII, 5)
