Privacy Policy

This privacy policy discloses the privacy practices for The Physics Classroom website ( This privacy notice applies solely to information collected by this website. It will notify you of the following:

  1. What personally identifiable information is collected from you through the website, how it is used and with whom it may be shared.
  2. Why we occasionally ask for a student name or other information.
  3. Information about our Ad displays.
  4. How you can correct any inaccuracies in the information.

Information Collection, Use, and Sharing 
We are the sole owners and decision-makers regarding the policies of this website and the personal information that it requests and collects. We only have access to/collect information that you voluntarily give us via email or other direct contact from you. We will not sell or rent this information to anyone.

We will use your information to respond to you, regarding the reason you contacted us. We will not share your information with any third party outside of our organization, other than as necessary to fulfill your request, e.g. to ship an order.

Unless you ask us not to, we may contact you via email in the future to tell you about improvements, new products or services, or changes to this privacy policy. 

The Purpose of Asking for Personal Information 
As of this writing, there are two sections on our website where we ask a user to enter a name and/or student ID numbers. These sections are the Concept Builders section and the Minds On Physics Internet Modules section. In both instances, the information that the user enters never goes any further than the browser window. It is not sent to any database on our website or to any other database anywhere. We will never know what information that you have entered into the text entry field. That information remains 100% private. The only person who will ever view that data is the person who looks at the screen.

So why do we ask for a name and/or student ID number? That data is stored in the RAM of the device as the peson works on the activity. Upon completion of the activity it is then displayed on he screen with some form of completion indicator that can be shown to the student's teacher. This allows the teacher to validate that the person who completed the activity is the person whose name appears on the screen. That is the sole purpose for asking for a name. Nobody at The Physics Classroom or anywhere else will ever know what name was entered because it is never collected and stored.

In the case of the Minds On Physics Internet Modules, we ask for a student ID number instead of a name. The only person who ever needs to know that number is the teacher and the student. It can be any number that the teacher and/or student wishes it to be as long as it is 4-6 digits in length. It an have no personal significance whatsoever. We do not collect the ID number nor is it ever associated with any name or other identifying information. Once the Minds On Physics activity is completed, the number will be used by the program to create an encrypted completion code (known as a success code) and then published on the screen. The success code is written down by the student and handed to the teacher. The teacher is able to decrypt the success code in order to determine validate that the person with the entered ID number indded completed the assigned activity. All algorithms for creation of the success code are executed in the RAM of the device. Data is never transfered from the client computer to our servers in the process. If the student wishes, the success code can be saved as a cookie on that device for future collection. This is entirely optional and is only done if the student clicks on the Save Success Code button.

Ad Displays 
The Physics Classroom displays ads on most of its pages. The ads are part of the Google Adsense program. We make no individual decisions regarding what ads display on a particular page for a particular student. All such decisions are governed by Google.

We have a limited amount of control over which ads or what type of companies can display ads upon our website. We do exercise such control in an effort to prevent ads with objectionable content from displaying. There are entire categories of ads which should never appear on our screen because we have disabled such categories. For instance, advertisements for alcohol, tobacco products, lingerie, etc. should never appear on our pages since we have disabled these categories. We are also able to block ads that link to particular websites that might be considered objectionable and we do exercise such ablities to block ads. When we hear from teachers or parents about an objectionable ad, we use access to our Adsense account to locate the ads and block them. 

It is important that users of our website recognize the importance of the Adsense program to our ongoing operations. It is one of our main sources of revenue and without it we would never be able to support the work of programmers and content providers nor pay for servers, content management systems, and other costs incurred on an annual basis. The implementation of the Adsense program allows us to provide a FREE website that serves many millions of students every year. While the above practices do not guarantee the display of unobjectionable ad content, we pledge to be vigilant about the ad content that displays on our website in order to keep all content appropriate. We are always appreciative of reports from parents and teachers to help us remain faithful to this pledge.


If you feel that we are not abiding by this privacy policy, you should contact us immediately via email.
