How does CDCK collect data about me?

CDCK collects data about you:

  • when you browse a forum that CDCK hosts
  • when you create and use an account on a forum that CDCK hosts
  • when you post, send private messages, and otherwise participate in a forum that CDCK hosts

CDCK collects data when you use forums that Discourse hosts, whether you use the forums using a web browser on your own computer, or use CDCK’s Discourse apps for mobile devices.

What data does CDCK collect about me, and why?

CDCK collects data about visits to forums.

When you visit a forum that CDCK hosts, whether you have an account or not, the forum uses cookies, server logs, and other methods to collect data about what pages you visit and when.

CDCK uses data about how you use the website to:

  • optimize the forum, so that it’s quick and easy to use
  • diagnose and debug technical errors
  • defend the forum from abuse and technical attacks
  • compile statistics on forum and topic popularity
  • compile statistics on the kinds of software and computers visitors use

CDCK usually stores data about how you use the forum in identifiable form for just a few weeks. In special circumstances, like extended investigations about technical attacks, CDCK may preserve log data longer, for analysis. CDCK stores aggregate statistics about use of the forum for as long as CDCK hosts the forum, but those statistics don’t include data identifiable to you personally.

CDCK collects account data.

Many features of forums that CDCK hosts require a forum account. For example, most forums that CDCK hosts require an account to post and reply to topics.

To sign up for a forum account, Discourse requires your name, a user name, and an e-mail address.

CDCK uses your account data to identify you on the forum, and to create pages specific to you, like your profile page. If the forum is public, CDCK publishes your account data. If the forum is access-restricted, CDCK makes your account data available to everyone who can access the forum, according to the forum administrator’s configuration.

CDCK uses your e-mail address to:

  • notify you about posts and other activity on the forum
  • reset your password and help keep your account secure
  • contact you in special circumstances related to your account
  • contact you about legal requests, like DMCA takedown requests

You may provide additional data for your account, like a short biography, your location, or your birthday, on the profile settings page for your account. CDCK makes that data available to others who can access the forum. You don’t have to provide this additional information, and you can erase it at any time.

CDCK stores your account data as long as your account remains open.

CDCK collects data about posts and other activity on the forum.

CDCK collects the content of your posts, plus data about bookmarks, likes, and links you follow in order to share that data with others, through the forum. If the forum is public, CDCK publishes your activity. If the forum is access-restricted, or access restrictions apply to the specific post, CDCK makes your activity available only to users permitted to see it.

CDCK also collects data about private messages that you send through the forum. CDCK makes private messages available to senders and their recipients, and also to forum administrators.

CDCK stores your posts and other activity as long as your account remains open.

How can I make choices about data collection?

You can make choices about how data about you is used on the settings page for your account. When a forum uses access restrictions that vary by category, you can choose who will see your post by choosing the appropriate category.

CDCK does not respond to the Do Not Track HTTP header.

Where does CDCK store data about me?

Does CDCK comply with the EU General Data Protection Regulation?

CDCK respects privacy rights under Regulation (EU) 2016/679, the European Union’s General Data Protection Regulation (GDPR). Information that GDPR requires CDCK to give can be found throughout this privacy notice. So can information about specific rights, like access, rectification, erasure, data portability, and objection to automated decision-making.

Where can I access data about me?

You can see your account data at any time by visiting your account page on the forum. Your account page also lists your posts and other activity on the forum.

Your account activity page also includes a link to download all of your activity in standard comma-separated values format.

How can I change or erase data about me?

You can change your account data at any time by visiting the profile settings page for your account. The settings for a particular forum may also allow you to close your account, on the settings page for your account. Closing your account starts a process of erasing or anonymizing CDCK’s records of data you provided for your account. Forum administrators can also erase and anonymize accounts.

Depending on the settings for your particular forum, you may also be able to edit, anonymize, or erase your posts. When you edit posts, CDCK will keep all versions of your posts. Forum administrators can view old versions of posts, and optionally make them visible to other forum visitors.

Does CDCK make automated decisions based on data about me?

CDCK classifies posts as spam automatically.

CDCK uses data about your posts and other activity on many forums to make automated decisions about whether your posts to and most forums that CDCK hosts are spam. When Akismet decides that a post is likely spam, the forum refuses to accept the post.

If you think a post has been wrongly blocked or removed, contact an administrator of your forum. They can override the decision that a post was spam.

CDCK uses data about posts and activity to set trust levels automatically.

Depending on how administrators of your forum configure the forum, the forum may use data about your posts and activity to award you badges and calculate a trust level for your account. Your trust level may affect how you can participate in the forum, such as whether you can upload images, as well as give you access to moderation and management powers in the forum. Your trust level therefore reflects forum administrators’ confidence in you, and their willingness to delegate community management functions, like moderation.

If you think your trust level has been set incorrectly, contact an administrator of your forum. They can manually adjust the trust level of your account.

Does CDCK share data about me with others?

CDCK shares account data with others as [mentioned in the section about account data]

CDCK shares data about your posts and other forum activity with others as [mentioned in the section about account data]

Apart from making data available to the customer that pays CDCK to host a forum, CDCK does not sell or give information about you to other companies or services. However, CDCK does use services from other companies on some forums that it hosts. The companies behind those services may collect data about you on their own, for their own purposes. Some of these services may be used to collect information about your online activities across different websites. All of these services are based in the United States.

Other individuals and companies may also reuse data about you that CDCK publishes, such as your posts to public forums.
