Can is usually used in standard spoken English when asking for permission. It is acceptable in most forms of written English, although in very formal writing, such as official instructions, may is often used instead: Persons under 14 unaccompanied by an adult may not enter.

You use can to indicate that someone has the ability or opportunity to do something. Don't worry yourself about me, I can take care of myself. I can't give you details because I don't actually have any details. The United States will do whatever it can to help Greece.

The present tense negative can not is usually contracted to cannot (more formal) or can’t (less formal). The use of can in asking permission is sometimes criticized as being impolite or incorrect by those who favour the more formal alternative “may I...?”.

Used to indicate possession of a specified power, right, or privilege. The president can veto congressional bills.

"Can" is one of the most commonly used modal verbs in English. It can be used to express ability or opportunity, to request or offer permission, and to show possibility or impossibility.
