Blocking Steamcloud Uploads 
What happens when data no longer belongs to oneself, shows a report from Oracle , which was blown up in August 2022 when Oracle was catched by selling data of 5 billion people for a price of 42.4 billion.
Valve provides players a simple view of the uploaded content in Steam.
You can reach the page in the Steam client via Help » Steam Support » My Account » Data of your Steam Account » Steam Cloud
After login alternatively under the link: https://store.steampowered.com/account/remotestorage
For the example, data from Dead Cells is used.
The "Folder" should actually show the location where the storage structure can be found, but Steam has its own labels or they are missing as here, completely and apart from downloads per file players have no possibility to delete. Also a function to mark all files to load everything in one go... missing.
Content uploaded via the Steam chat will be sent to Google as well as Akamai at the same time. The structure of Akamai Technologies, represents the primary platform of Steam. The upload itself runs via the steamwebhelper.exe.
Addressed servers differ according to the player location. The entries can be copied if necessary and transferred directly to your hosts or list for a used DNS resolver.
Recently, data is also uploaded directly to an Ipv4 address, so that host entries no longer count. In this case, the Ipv4 must be blocked via a firewall
The upload of user-generated content such as images in the chat, screenshots, avatars, photos or other things must be considered separately, because Valve has implemented an external filter and analysis system for external content over time. Google Vision AI and Amazon Recognition are used for this purpose.
In the case of Amazon, data security is not guaranteed in any way, because an article from 2018 shows that they sell data to authorities . At the time, the Amazon Ring surveillance systems were not even considered.
Uploading personal data should generally be avoided.

Are entries missing? Send them by contact form so that the list can be completed.
The settings provided to us in Steam itself are marginal at best and do not include the cloud information for uploading user-generated content such as screenshots or videos that are uploaded e.g. in chat or in general. Also missing information are which providers get our data, because the "Steamcloud" consists of different servers that are located all over the world.
What services are used for the Steamcloud?
- Google Cloud Storage by Google, LLC
- Microsoft Azure Blob Storage by Microsoft Corporation
- Amazon Simple Storage Service by Amazon.com, Inc.
- Oracle Cloud by Oracle

Blocking of Steam Cloud
In addition to the official settings for switching off the cloud in the Steam client, there is the possibility to control the behavior via your own filter entries. This has the advantage that
- Servers are to be controlled individually
- New users can directly switch off the behavior before starting the client
- Users have more control
- Valve does not get any user settings made in the Steam client
Addressed servers differ according to the player location. The entries can be copied if necessary and transferred directly to your hosts or list for a used DNS resolver.

Upload of data despite deactivated user settings
Finally, something that was briefly mentioned at the beginning. Despite deactivated settings, the Steam Client repeatedly uploads data and consults with various cloud servers.
The result is that the settings in the client are useless and the program behaves differently than it wants to believe.

Steam uses various connections to offer the basic functionality of Steam. Any active connections you see are part of the processing and fulfillment of whatever feature(s) you are using at that time.
As you know, the Steam Cloud can be toggled for individual games, or as a global Steam setting for all games.
When Steam Cloud functionality of a game is disabled, all progress that would normally be saved via the cloud will only be saved locally on the machine where the progress was made.
