When you use Siri and Dictation, Apple processes what you say to improve Siri's understanding and to provide personalized suggestions. Voice recordings may be retained for a period of time to improve Apple's products and services.
Voice data can inadvertently capture sensitive conversations, third-party speech, and private information; its retention by a technology company for product improvement purposes raises significant privacy concerns, particularly if users are unaware of how long recordings are kept.
Apple collects a broad range of personal data including location, health and fitness information, financial data, voice recordings, and browsing and search history across its entire ecosystem of devices and services, and shares this information with Apple subsidiaries worldwide, app developers, business partners, and advertisers. While Apple publicly commits to not selling personal data, the policy permits extensive intra-group sharing and third-party disclosures that may not be fully transparent to average consumers. You can review, download, correct, or delete your personal data by visiting privacy.apple.com and signing in with your Apple ID.
