Privacy Policy of this website

This Privacy Policy applies to the website operated by Raster Research, LLC. The purpose of this policy is to tell you how we use personal information we collect about you on this website.

What personal data we collect and why we collect it

Contact form

The personal data collected from the contact form on this website is your name, email address, and message entered on the form. These data are used to respond to your message. And we retain these data for customer service purposes, but we do not use these data for marketing purposes.

Log Data

When you use our website our servers automatically record information about your browser. This information called Log Data includes your computer’s IP address, the date and time of your visit, your web request, status code for your request, the web address that you were visiting before accessing our website, and your browser type and version information.

Google reCAPTCHA

We use Google reCAPTCHA on our website. This service is provided by Google. Google reCAPTCHA is used to check whether the data entered on our websites (such as on a contact form) has been entered by a human or by an automated program. The service includes sending data required to do this to Google. For more information about Google reCAPTCHA, please visit Google’s privacy policy at .


When visitors leave comments on the site 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: After approval of your comment, your profile picture 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 visit our contact page, Google reCAPTCHA embedded in the page sets some cookies required for the reCAPTCHA service. Additional information about Google reCAPTCHA is available at Google’s privacy policy.

And if you use the contact form, some cookies will be set that are necessary for the form to work. These cookies are discarded when you close your browser.

If you leave a comment on our site you may opt-in to saving your name, email address and website in cookies. These are for your convenience so that you do not have to fill in your details again when you leave another comment. These cookies will last for one year.

If you visit our login page, we will set a temporary cookie to determine if your browser accepts cookies. This cookie contains no personal data and is discarded when you close your browser.

When you log in, we will also set up several cookies to save your login information and your screen display choices. Login cookies last for two days, and screen options cookies last for a year. If you select “Remember Me”, your login will persist for two weeks. If you log out of your account, the login cookies will be removed.

If you edit or publish an article, an additional cookie will be saved in your browser. This cookie includes no personal data and simply indicates the post ID of the article you just edited. It expires after 1 day.

Embedded content from other websites

Articles on this site may include embedded content (e.g. videos, images, articles, etc.). Embedded content from other websites behaves in the exact same way as if the visitor has visited the other website.

These websites may collect data about you, use cookies, embed additional third-party tracking, and monitor your interaction with that embedded content, including tracking your interaction with the embedded content if you have an account and are logged in to that website.

How long we retain your data

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.

For users that register on our website (if any), we also store the personal information they provide in their user profile. All users can see, edit, or delete their personal information at any time (except they cannot change their username). Website administrators can also see and edit that information.

What rights you have over your data

If you have an account on this site, or have left comments, you can request to receive an exported file of the personal data we hold about you, including any data you have provided to us. You can also request that we erase any personal data we hold about you. This does not include any data we are obliged to keep for administrative, legal, or security purposes.

Where we send your data

Visitor comments may be checked through an automated spam detection service.
