Question & Answer

• Why not manually install flags?
  • Manually installing flags is time consuming. When Roblox updates, you must remember to install the flag file manually again, while Roblox Client Optimizer will handle this operation automatically.
  • If a major bug is found within the flag file, there is no way for us to notify you to update it, therefore we've implemented measures to automatically update our flag list if such a problem arose.
• Will the software slow down my computer?
  • No, the software is very lightweight and only checks for updates to our flag list and updates to itself. Additionally, we use a content delivery network powered by Cloudflare and Fastly to optimize the bandwidth usage and file size of any flag file or downloads that the software makes.
• Will I get banned for using this?
  • No, our operations are fully compliant with the Roblox Terms of Use, and we use a method that Roblox themselves intentionally added to the client to modify flags. Roblox Client Optimizer remains operational regardless of anti-cheat measures, as we do not inject a DLL nor modify live client memory - our software is not an exploit, or a tool used to aid in exploiting.
• What are flags?
  • The Roblox engine uses a system called fast flags as part of the deployment process. When code is shipped, not all of it is active by default. Rather, the changes are enabled and disabled dynamically via FFlags, even after the code is live in production. We welcome you to read more about flags here and here.

Disclaimers

• Do we collect and store user data?
  • No, the program itself does not collect ANY data, telemetry, or analytics from our users. The only possible data transferred is due to your use of Roblox Client Optimizer, where the IP address of your devices is required to connect to the internet and therefore update Roblox Client Optimizer and the flag list, however our content delivery providers have an agreement with us called a Data Processing Addendum, which restricts them from using your data (just your IP address) outside of delivering the files to you that Roblox Client Optimizer requests.
• What happens to time wasting issues and pull requests?
  • Posting time wasting issues and pull requests may result in your account being blocked from the repository. Please ensure all contributions are meaningful and correct. Before posting an issue, try to make sure there is not already one regarding your issue, if there is, we welcome you to comment on it.
