Storing user information as RC4 - safe?

Hi, I'm coding a program where I wish to store user data in RC4 format for privacy.
Such info will be whatever the user wants, eg. web URLs, passwords, etc. Would RC4
suffice for that, assuming I force them to use a 10-character password as minimum,
with at least 1 x lowercase alpha, 1 x uppercase alpha, 1 x numeric digit, and
1 x other character?
