When iCloud settings sync is enabled, API keys replicate through iCloud Keychain and eligible preferences, statistics, dictionary data, and voice history may sync through your private iCloud account. Voice history is capped at 300 entries and can be cleared from History or by resetting settings. Clipboard history remains device-local, is capped at 15 entries, has no fixed expiry, and remains when capture is turned off or settings are reset; use the separate confirmed clear action to delete it. Chinese and English typing-learning data stays local and can be cleared from typing settings without deleting the personal dictionary. Downloaded Mac speech models remain until you remove the model in the app or delete its local files.</p>
   <p><strong>Optional account</strong> — account profile, credit ledger, StoreKit audit records, and limited anti-abuse records are retained by the account service while the account is active. Account deletion removes the active profile and credentials; pseudonymous ledger, purchase-audit, and time-limited anti-abuse records may remain where required to prevent replay, fraud, or abuse.</p>
