Privacy Policy

Your privacy is very important. It is the policy of How To Study Blockchain to respect your privacy regarding any information we may collect. We don’t ask you for personal information unless we truly need it and we don’t share your personal information with anyone except to comply with the law, improve our content, or protect our rights.

Website Visitors

Like most websites, How To Study Blockchain 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. The purpose for collecting this non-personally-identifying information is to better understand how visitors use the website.

How To Study Blockchain also collects potentially personally-identifying information like Internet Protocol (IP) addresses for users leaving comments. How To Study Blockchain only discloses commenter IP addresses under the same circumstances that it uses and discloses personally-identifying information as described below.

Gathering of Personally-Identifying Information

Certain visitors to How To Study Blockchain choose to interact with the website in ways that require personally-identifying information to be gathered. The amount and type of information that is gathered depends on the nature of the interaction.

For example, How To Study Blockchain asks visitors who choose to leave comments to provide a name, email address, and website (optional). We collect the data shown in the comments form, and also the visitor’s IP address and browser user agent string to help spam detection. An anonymized string created from your email address (also called a hash) may be provided to the Gravatar service to see if you are using it. The Gravatar service privacy policy is available here: Visitor comments may be checked through an automated spam detection service. After approval of your comment, your profile picture (if you chose to upload one) is visible to the public in the context of your comment. If you upload images to the website, you should avoid uploading images with embedded location data (EXIF GPS) included. Visitors to the website can download and extract any location data from images on the website. If you leave a comment, the comment and its metadata are retained indefinitely. This is so we can recognize and approve any follow-up comments automatically instead of holding them in a moderation queue.

Similarly, visitors to the website who choose to complete the contact form are asked to provide a name and email address. In each case, How To Study Blockchain collects such information only insofar as is necessary or appropriate to fulfill the purpose of the visitor’s interaction with the website. How To Study Blockchain 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.
