As users can place pixels on the canvas, we log these changes. For each change we store the rgb-values, the x and y-position, timestamp, user id of the user that placed it and whether or not it was reverted. We store this with the goals that users can check who placed a pixel, know what color a pixel at a given position is, when a pixel was changed, to see who contributed on a drawing and to make timelapses. Moderators can revert changes of a user as a way to deal with griefing. This way, the data can be used as dataset to automatically detect griefing in the future.
Users can decide to mark an area. For an area we store the boundaries of the area, when it was marked and by whom. The user is also able to give it a title. The user who created the area marking, is able to freely delete it at any time.
Users can also leave comments on a marked area. For these comments, the id of the marking is stored, as well as the user id of the user who created the comment, timestamp and body of the comment such that other users can view them.
When a user purchases a custom color at the shop, we need to store the rgb values that the user has selected and relate them to the user’s id.
Nothing. We don't specifically share any data with third parties. We do however, consider the data as free for public use. For example, anyone is allowed to see the pixels that have been placed, and by whom.
