These analytics do NOT include any personally identifiable information about you. IP addresses are redacted to protect your privacy. Ad tracking and ad personalization features are disabled.
We use this information to improve your experience on this site and improve the content on this site.
When you use the search bar on this site, the query and whether any results were clicked shows up in the backend metrics. However, no identifying information or location information is included in those statistics. I use the metrics to improve search performance and indexing.
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.
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 choose to use a contact form on this site, a record of your message will be kept in the password-protected backend of this site and also sent to an email address that uses Google Apps.
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.
Who we share your data with
Your data is kept confidential and not shared with anyone else.
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. We use Mailpoet‘s servers to deliver newsletters.
