Data retention

Roduko keeps data only for as long as reasonably needed to provide the game, support reconnects, show results, maintain profiles, prevent abuse, respond to support requests, and operate the service. Active room and gameplay data may be kept for a limited period after a game ends so results, reconnects, and reliability features can work. Profile, challenge, social, and notification data may be kept while your Roduko profile remains active. Technical logs are kept for a limited period for debugging, security, and reliability. Deleted data may remain in backups for a limited time until those backups expire or are overwritten.
