We retain information only as long as reasonably necessary for the purposes described in this Policy, including legal compliance, dispute resolution, security review, and agreement enforcement.
Local gameplay data, such as settings, statistics, and challenge progress, may remain on your device and can usually be removed by uninstalling the app, subject to any platform-level backup behavior.
7. Data Security
We use reasonable administrative, technical, and organizational safeguards to protect information against unauthorized access, misuse, loss, or alteration. No system is completely secure, so absolute security cannot be guaranteed.
