Unique client ID (UUID) is generated on user's machine and stored at global configuration file. It assigned to each Legacy Launcher installation.

Generally, we collect data to analytics server, Sentry and Pasta.

Analytics server is aimed to collect data that helps us understand trends within the players community. It is also used to evaluate our ads performance. Currently the user can't opt out of sending their data to the analytics server, but they can disable ads in the launcher.

We collect the following data (“General user info”) on each data submission:

• Unique client ID (UUID), that is generated on user's machine and is assigned to each Legacy Launcher installation
• User's country, that is determined from user's IP address that is used to communicate with our statistics endpoint)
• Locale name, that is provided by user's OS.
• Launcher version and brand

When launcher is not closed, periodically it sends (“beacon”) the following data:

• General user info

We collect the following data when you launch the game:

• General user info
• Account type (mojang, minecraft, ely, plain, mcleaks, etc)
• Minecraft version ID
• Server ID, that is supplied when you click on an advertisement in the launcher
• Promotion status, that equals to: “success” if the launcher managed to add promoted servers into servers.dat, or “disabled” if the user disabled this feature, or “error” otherwise.

Sentry is the error-tracking software that helps us fix bugs and enhance application stability.

When various parts of Legacy Launcher enter an unexpected or unwanted state, they may submit an automated report that contain user's Unique client ID, an error message, a stack trace and other data that may help us to troubleshoot an issue. Sometimes this data may contain sensitive information (like passwords), but it is never enclosed to the third parties and is not retained for a long time.

When the user encounters an error, they might be asked to “send us the logs”. This is where Pasta comes in. Logs privacy policy is described here.

The launcher also might use Pasta to send the data as part of Sentry's automated reports. For example, if we suspect that the file's content has been corrupted, we upload this file to Pasta, exchange the file's ID, and then include it into the Sentry report. This way we can ignore the limits on Sentry's report size.
