What personal data we collect and why we collect it

Security Audit Log

We use a plugin to monitor changes and to find potential bugs: WP Security Audit Log, a real-time audit log & tracking for WordPress developed by the team at WP White Security.

We store your IP-Address, your username (Website Visitor) and your user agent (what browser version and operating system you are using). We store this information for up to 12 months, and we may look up your ISP for further investigations.


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.

Contact forms

We use a contact form plugin: Caldera Forms is a free WordPress form builder plugin developed by Josh Pollock and Caldera Labs. We store all the information you provided us for 6 months, but we don't use them for marketing purposes. We don't store your IP-Address when submitting a form. Verify Email for Caldera Forms is a form processor that sends a validation link to the submitters email address to verify the email entered is valid. Once the link is clicked, the form submission is completed. This can be used for both anti-spam and confirming the email address is correct before sending the form.


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 have an account and you log in to this site, 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 tracing 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.

Additional information

How we protect your data

We keep our website up-to-date with the latest updates and security features. We ensure a regular maintenance and cleanup to guarantee that your data isn't lost.

What data breach procedures we have in place

We use a security plugin to keep potential hackers out and to track their attempts: iThemes Security by iThemes works to lock down WordPress, fix common holes, stop automated attacks and strengthen user credentials.

  • WordPress Brute Force Protection: Limit the number of failed login attempts allowed per user with WordPress brute force protection. If someone is trying to guess your password, they'll get locked out after a few attempts.
  • File Change Detection: If someone manages to get into our site, they'll probably add, remove or change a file. We get email alerts showing any recent file changes so we know if we've been hacked.
  • 404 Detection: If a bot is scanning our site for vulnerabilities, it will generate a lot of 404 errors. iThemes Security will lock out that IP after the limit we set (20 errors in 5 minutes by default).
  • Strong Password Enforcement: Set which level of users on our site (admins, editors, users, etc.) need to have strong passwords. Strong password enforcement is one of the best ways to lock down WordPress.
  • Lock Out Bad Users: Keep bad users away from our site if they have too many failed login attempts, if they generate too many 404 errors, or if they're on a bot blacklist.
  • Hide Login & Admin: Change the default URL of your WordPress login area so attackers won't know where to look. This feature is also great to help clients remember their login link.

What third parties we receive data from

We don't receive data from third parties.

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

We don't support automated decision making and/or profiling with user data yet. If we plan to add this in the future, we'll inform you in time.
