AwesomeOrange89 is correct.

The only exception to this rule is if you host a wiki that is victim to abnormal spam and vandalism to a degree that makes locking the wiki you have created to only allowed users, however this is extremely rare and only used in seriously egregious circumstances regarding extreme vandalism.

Beyond that, anyone is allowed to access you wiki, anyone is allowed to edit your wiki, and anyone is allowed to report/quote/post links to your wiki. While you can ban users for posting on or editing your wiki, this can come with serious ramifications, especially if you come across a particularly vicious troll who takes it as a challenge to do his/her best to damage the heck out of your wiki. Furthermore, it can place you in somewhat of a bad light and make users or the general public call it some kind of personal club nobody is allowed to touch but yourself. I'm not saying that that is your intent, but remember, everyone will interpret it as they see it. What is just a personal website to one person can be seen by another as an attempt to 'show off' or something of similar design. You can't have it taken down for that, but, like I said before, trolls will see it as a challenge and individuals who take it (not be allowed to the site) personally will pester you.

Finally, even if you do get some kind of "Secret" website, remember there's little that you can do to stop Google from displaying it, and even less to stop other search engines that entirely skip over 'secret' designations to websites and display them anyways.

Also, remember that anything and everything you post on a wiki becomes part of a Creative Commons license, so if your goal is to create a wiki around something personal to yourself, you do give permission to anyone to use it under the CC license. For more information, I would take a look over on the Privacy Policy, Terms of Service, and do some legal checking on the CC License as it stands currently today and all of its provisions.

If your goal is to test some features or something, then Awesome Orange has the best idea for a test wiki. Another option are wiki's solely designated for allowing users to test their coding or functions, and are created by other users.

If you want a website that others can't edit and nobody can see it, I would just do it all offline on your own computer. It saves you the trouble of having to shop around for a site, and saves you from having to pay for one.
