How to disable ALL (absolutely all) markers. (Assassin's Creed: Unity)

Gentlemen, tell me how to cut down all the clues in the game. In the menu I disable (All HUD off) but the markers you "Follow" (follow) still remain.
And the 2nd question, WHERE can I read the "in-game library" outside the game (Character biographies, etc.) I want to read on my smartphone, for example, while in line or in the subway.
