Our website address is: https://www.marimba.org.

What personal data we collect and why we collect it


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: https://automattic.com/privacy/. 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.

Contact forms

We obtain the data you provide us through the contact forms and emails.


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.


We use Jetpack and we may potentially use Google Analytics for the analytics purpose.

Who we share your data with

We will not sell or share our data with a third party.

Please note that we use data processors such as Spam processors and analytic processors. Your data may be sent to them for the purpose of processing but as they are not data controllers, they cannot use your data for any other purpose.

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.

Your contact information

Your contact information that you give to us will be used solely for the service that this site provides.

Additional information

How we protect your data

We are storing your data on the disk system and the database that only approved persons with cryptographic keys can access directly. We strive to maintain the site’s software up-to-date so as to minimize the exploit through a known bug.

The software we use for this site is WordPress and the underlying system is the LAMP stack. The mail server is also maintained by ourselves.

The data is backed up weekly so the data for a maximum period of a week may be lost.

What data breach procedures we have in place

When we become aware of the data breach, we will notify you to your registered email address.

What third parties we receive data from

Through your authorization, we may receive data from through OpenID Connect providers and other social login providers.

What automated decision making and/or profiling we do with user data

We use SPAM protection software. Depending on what you post, you may be automatically classified as a spammer and prevented from posting.

Industry regulatory disclosure requirements

While the server currently resides in the United States to minimize the latency, the service as a whole is being managed from Japan. Thus, regulatory reporting will be done according to the Japanese Personal Information Protection Act.
