Match and training result data needed for ranking and history (for example: mode, counts, scores, winner, and play date/time).

Training performance metrics tied to your records, such as shot accuracy, receive reaction time, and T-zone recovery reaction time.
Your personal training records and a play-activity history (start, level completion, finish, ranking registration) shown on your My Page when signed in.
Country code data inferred from your public IP address (for example, KR, US) for leaderboard and match profile display.
Technical/session data required for operation, such as room IDs, connection status, browser session tokens, language preference, and Court View shot sequences stored in your browser.

When available, country code is stored together with match/training records for consistent history display.
If country cannot be inferred (for example, private/local network IP), the country code may be saved as empty.
Language, session tokens, and some client-side preferences — and Court View shot sequences you create — are stored in browser local storage.
Data is retained as long as needed for service operation unless deletion is requested or legally required.

We do not sell your personal data.
Data is shared only when required to run core service features (for example, online match synchronization).
