Privacy Policy

Your privacy is critically important to us. At Kepler we have a few fundamental principles:

  • We don’t ask you for personal information unless we truly need it. (We can’t stand services that ask you for things like your gender or income level for no apparent reason.)
  • We don’t share your personal information with anyone except to comply with the law, develop our classes or services, or protect our rights.
  • We don’t store personal information on our servers unless required for the on-going operation of one of our services.
  • In our community, we aim to make it as simple as possible for you to control what’s visible to the public, seen by search engines, kept private, and permanently deleted.

Below is our privacy policy which incorporates these goals:

Website Visitors

Like most website operators, Kepler collects non-personally-identifying information of the sort that web browsers and servers typically make available, such as the browser type, language preference, referring site, and the date and time of each visitor request. Keplers purpose in collecting non-personally identifying information is to better understand how Keplers visitors use its website. From time to time, Kepler may release non-personally-identifying information in the aggregate, e.g., by publishing a report on trends in the usage of its website.

Kepler also collects potentially personally-identifying information like Internet Protocol (IP) addresses for logged in users and for users leaving comments on its website. Kepler only discloses logged in user and commenter IP addresses under the same circumstances that it uses and discloses personally-identifying information as described below, except that comment IP addresses may be visible and disclosed to the administrators of the article where the comment was left.

Gathering of Personally-Identifying Information

Certain visitors to Kepler's websites choose to interact with Kepler in ways that require Kepler to gather personally-identifying information. The amount and type of information that Kepler gathers depends on the nature of the interaction. For example, we ask visitors who subscribe to our newsletters or attend a free webinar to provide at least a username and email address. Those who engage in transactions with Kepler – by signing up for a class or purchasing an item are asked to provide additional information, including as necessary the personal and financial information required to process those transactions. In each case, Kepler collects such information only insofar as is necessary or appropriate to fulfill the purpose of the your interaction with Kepler. Kepler does not disclose personally-identifying information other than as described below. And visitors can always refuse to supply personally-identifying information, with the caveat that it may prevent them from engaging in certain website-related activities.

Aggregated Statistics

Kepler may collect statistics about the behavior of visitors to its websites. For instance, Kepler may monitor the most popular blogs. Kepler may display this information publicly or provide it to others. However, Kepler does not disclose personally-identifying information other than as described below.

Protection of Certain Personally-Identifying Information

Kepler discloses potentially personally-identifying and personally-identifying information only to those of its employees, contractors and affiliated organizations that (i) need to know that information in order to process it on Kepler's behalf or to provide services available at Kepler's websites, and (ii) that have agreed not to disclose it to others. Some of those employees, contractors and affiliated organizations may be located outside of your home country; by using Kepler's websites, you consent to the transfer of such information to them. Kepler will not rent or sell potentially personally-identifying and personally-identifying information to anyone. Other than to its employees, contractors and affiliated organizations, as described above, Kepler discloses potentially personally-identifying and personally-identifying information only in response to a subpoena, court order or other governmental request, or when Kepler believes in good faith that disclosure is reasonably necessary to protect the property or rights of Kepler, third parties or the public at large. If you are a registered user of the Kepler website and have supplied your email address, Kepler may occasionally send you an email to tell you about new features, solicit your feedback, or just keep you up to date with what’s going on with Kepler. We primarily use our newsletter and website to communicate this type of information, so we expect to keep this type of email to a minimum. If you send us a request (for example via a support email or via one of our feedback mechanisms), we reserve the right to publish it in order to help us clarify or respond to your request or to help us support other users. Kepler takes all measures reasonably necessary to protect against the unauthorized access, use, alteration or destruction of potentially personally-identifying and personally-identifying information.


A cookie is a string of information that a website stores on a visitor’s computer, and that the visitor’s browser provides to the website each time the visitor returns. Kepler's course site uses cookies as well as the main website to help Kepler identify and track visitors, their usage of the website, and their website access preferences. Kepler visitors who do not wish to have cookies placed on their computers should set their browsers to refuse cookies before using Kepler's website, with the drawback that certain features of Kepler's websites may not function properly without the aid of cookies.

Business Transfers

If Kepler, or substantially all of its assets, were acquired, or in the unlikely event that Kepler goes out of business or enters bankruptcy, user information would be one of the assets that is transferred or acquired by a third party. You acknowledge that such transfers may occur, and that any acquirer of Kepler may continue to use your personal information as set forth in this policy.


In general, as a non-profit corporation, Kepler does not have advertising on its website. However, in those cases where there is an ad that may be delivered to users by advertising partners, these partners may set cookies. These cookies allow the ad server to recognize your computer each time they send you an online advertisement to compile information about you or others who use your computer. This information allows ad networks to, among other things, deliver targeted advertisements that they believe will be of most interest to you. This Privacy Policy covers the use of cookies by Kepler and does not cover the use of cookies by any advertisers.


Comments and other content submitted as part of your community interaction are saved on our servers unless they were deleted because they were spam, off topic or offensive, in which case we store them long enough to ensure it won't happen again.

Privacy Policy Changes

Although most changes are likely to be minor, Kepler may change its Privacy Policy from time to time, and in Kepler's sole discretion. Kepler encourages visitors to frequently check this page for any changes to its Privacy Policy. If you are registered on the site, you should also check for alerts to these changes. Your continued use of this site after any change in this Privacy Policy will constitute your acceptance of such change.
