TL;DR
Apple is adding a new privacy feature to Siri in iOS 27, allowing users to set chat histories to delete automatically after 30 days, one year, or forever. This marks a shift from other AI chatbots that typically retain conversations temporarily.
Apple’s upcoming iOS 27 will include a revamped Siri capable of auto-deleting chat histories, a move that emphasizes user privacy and distinguishes it from competitors.
According to Bloomberg’s Mark Gurman, the new Siri will allow users to choose how long their chat histories are retained, with options for 30 days, one year, or permanent storage. This feature is a significant departure from other major AI chat services, which typically only offer temporary or incognito chats.
Apple’s approach appears to prioritize privacy by limiting how long conversation data can be stored, even as it incorporates Google’s Gemini technology into its AI systems. The company aims to make privacy a key differentiator in its AI offerings, potentially appealing to users concerned about data security and AI misuse.
Why It Matters
This development matters because it signals a shift in how major tech companies are handling user data in AI interactions. Apple’s focus on auto-deletion could set a new industry standard for privacy, influencing user expectations and regulatory discussions around data retention and AI transparency.
For consumers, this could mean greater control over personal data and increased trust in AI assistants, especially as concerns about data privacy and AI misuse grow globally.

Background
In recent years, AI chatbots have relied heavily on storing conversation histories to improve responses and personalization. Apple has historically been more privacy-conscious than competitors like Google and Microsoft, but it has integrated Google’s Gemini tech into its AI systems. The move to auto-deletion in iOS 27 aligns with Apple’s broader strategy to differentiate itself through privacy, even as it enhances AI capabilities.
This feature was first reported by Bloomberg’s Mark Gurman, who noted that Apple’s limits on data retention are part of its effort to turn perceived weaknesses into strengths in the AI space.
