Handling of your Personal Data
Collection and storing of Personal Data
The vast majority of our users are regular visitors or subscribers. Very few are registered users. Depending on how you use the website, we handle your data in the following ways:
- Registered users (authors): We store the names and email addresses of the small number of individuals who write and publish content on the website. This is done with their explicit consent. They have approved this.
- Subscribers: If you wish to subscribe to updates, you only need to provide a valid email address. You do not need to provide your name, create an account, or log in, and we do not save any information other than your email address. You can unsubscribe, at which point your address will be deleted from our mailing list.
- Visitors: As a regular visitor, you do not need to log in or provide any personal data. We do, however, use cookies to collect visitor statistics and to ensure the website’s features function correctly (see information about cookies below).
The information mentioned above is stored on a web server physically located in the US. The server is maintained and regularly updated to ensure that software security issues are proactively managed.
Embedded content from other websites
Articles on this site may include embedded content (e.g. videos from YouTube). 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. See detailed list below of cookies.
Who we share your data with
Third parties, such as YouTube, may collect information about you as mentioned above. Apart from this, we do not send any information to third parties. YouTube can’t collect any information about you if you only accept necessary cookies (but also makes embedded videos not working).
What third parties we receive data from
We do not receive information about you as a visitor from any third parties.
What rights you have over your data?
For the average visitor, we do not save any personal information. If you subscribe to updates, we only store your email address, which is automatically removed if you choose to cancel your subscription. For any questions, please contact Ronny Gunnarsson.
Registered users (currently limited to a few authors) can request an exported file of their personal data or ask us to delete it. Please note that we cannot erase data we are legally required to keep for administrative or security purposes.
