Who we are

We are a group of companies, based in the Netherlands, Hungary and Spain. We help our customers get their code run fast by optimizing the computations and using accelerators. We do this since 2010.


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 anonymised 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: https://automattic.com/privacy/. After approval of your comment, your profile picture is visible to the public in the context of your comment.


Form-data is sent to self-hosted software and is not read by any third-party party.


We use anonymized tracking to find out:

  • Which pages are visited how often
  • Which subjects are popular
  • Which pages are clicked through
  • From which countries or states the visitors are

During a visit/session, you get a random ID.


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.

Tracking cookies last for 24 hours.

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.

Who we share your data with

None of the data is shared with any third party. Marketing reports don’t contain any personal data.

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.

Anonymous tracking data is not thrown away, to find trends over the years.

What rights you have over your data

If you 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 your data is sent

Visitor comments and forms are checked through an automated spam detection service, ReCAPTCHA and Akismet.

Reporting problems

We are not in the business of monetizing user data, and believe in finding new customers through content.

As software and plugins change after updates, we are sometimes surprised that more is collected than we configured.

If anything is incorrect or not legal, please email to privacy@streamhpc.com. If you have generic questions, go to the contact page or email to info@streamhpc.com.
