Haven't used it but reading what it cleans...your concerns are often stored as cookies and in other caches. It's a bit of bother to put user names and passwords back in weekly but there's no cleaner that judiciously selects what you wish to keep and what not. Different cleaners have shown me where to go to do manual cleaning so I don't have to have an extra program. I delete all cookies and caches.
A good cleaner should allow the option to store deleted stuff and "undo" the cleaning if needed.
Ultimately, it forces people to keep a good list of user names-passwords.
Note: this one and others clean "not used for awhile" which I think can be dangerous. Check each entry before deleting.
