This is a list of simplex frequencies that are available for general usage in the Santa Clara Valley of California. As everyone knows, "repeaters are there to be used," but if you wish to conduct short-distance two-way communications using FM (frequency modulation) with other stations (friends, family), switching to simplex is "good amateur practice," allows others to use the repeater, and allows you to talk for as long as you want, without bothering others.
It is also "good amateur practice" to periodically leave long pauses between transmissions, in order to allow other stations to break into the conversation, if they have something to add, or if they have emergency traffic. And don't forget to identify your station every 10 minutes.
While nothing is exactly "private," your message will have less "exposure" on simplex than it will on a repeater. As always, if you don't want anybody to know what you're saying, don't say it on the radio!

Nothing in life is guaranteed.
These frequencies generally adhere to band plans set forth by regional and national organizations, but there are often local variations, so if you travel, check locally.
Some of these frequencies are used by local A.R.E.S. (Amateur Radio Emergency Services) and R.A.C.E.S. (Radio Amateur Civil Emergency Services) stations for weekly roll call and training sessions, and occasionally for emergency preparedness drills.
New hams should seriously consider getting involved in your city's A.R.E.S. emergency preparedness activities.
