In iOS 27, Siri has it’s own dedicated app, making it easy to hop back into past threads. And thanks to iCloud syncing, a conversation started on your iPhone sits waiting for you when you open your Mac.
If you take a look at your history, you’ll find a neatly archived and synced across your devices, a chronological list of your chats with Siri. Apple assumes you want to keep that paper trail forever.
Why forever is a problem
Under the old rules, Siri was ephemeral: ask a question, get an answer, done. iOS 27 flips that model. By saving everything by default, Apple turns Siri from a quick tool into a permanent digital diary.
The issue isn’t just about someone reading over your shoulder, it’s data bloat. Because these chats sync through iCloud across your devices, an indefinite log creates an avoidable footprint. Every health symptom you look up, draft message, and rabbit hole builds into a detailed map of your personal habits sitting in the cloud.
Convenience is great, but hoarding years of unfiltered search context is an unnecessary privacy liability when an auto-delete setting exists.
Auto delete Siri conversations on iPhone
Just like you can set all old messages to auto-delete, the new Siri app has a similar option to keep your experience clean and devoid of past baggage.
- Go to Settings and select Siri.
- Tap Keep Conversations.
- Select 30 Days or 1 Year instead of Forever. Remember that this feature applies retroactively, meaning if you select 30 Days, all current chats that are older than this will be permanently deleted now.
