The definition of log file (logs) can be found on Wikipedia. Everything we might consider significant in debugging is written into the logs. For example: current time, executable location, user name in the system, configuration of the launcher and Minecraft, output of launched applications, etc.
We send into the «Pasta» service (https://pasta.llaun.ch). This is private service. Nobody, except Legacy Launcher staff and their helpers, is authorized to read logs.
We don't share logs with third parties. Logs are stored only seven days after upload, but this period may be extended by administrator. You can ask us to delete your logs, if you want.
If you have any question regarding our privacy policy, or just want your data removed, please contact us: privacy@llaun.ch
