If you visit Google's Web History page, you can see every single Google search you've run, while signed into your Google account, for years. And it's not limited to text searches -- you can also see your history of Google image searches, Google video searches, Google Maps searches and so on. This data is stored by default; users must activate Web History to access it.

Need to track what web pages have been visited - even if that was done in Safe Browsing mode or the browsing History was deleted?

Local Shared Objects (LSOs), otherwise known as “Flash cookies”, are so-named because they are a function of Adobe’s Flash. These cookies don’t even show up in your cookie or other privacy settings - they are buried deep within your Adobe Flash settings.  They are accessible only (or at least only easily) by visiting a special page at Adobe.
