私is the standard, polite Japanese pronoun for I or me. It is used by both men and women in formal situations, and is the safest, most common first-person pronoun for beginners or when speaking respectfully to strangers or colleagues.
That is how Fuguro works. It brings 私 back for review right before you forget it, each time a little later, until it sticks for good. You hear it spoken aloud, and you meet it again in stories you can already read. The first five levels are free.
