Google is rolling out Gemini app updates that personalize responses using past conversations and add Temporary Chats for short-lived, non-saved interactions. The features start today on Gemini 2.5 Pro in select countries, with expansion to additional models and regions in the coming weeks. Google detailed the updates in a blog post.

Key Details
Personalization from past chats
Gemini can now reference earlier conversations to recall details and preferences in future replies. The setting is on by default and can be turned off at any time.
- Launch starts on Gemini 2.5 Pro. Expansion to 2.5 Flash and other models will follow in the coming weeks.
- Toggle path: Settings > Personal context > Your past chats with Gemini.
- On by default - can be turned off anytime.
Temporary Chats and privacy controls
Temporary Chats let you start conversations that do not influence future responses. Google says these chats have limited retention and are excluded from training.
- Temporary Chats do not appear in recent chats.
- They are not used to personalize or train models.
- Content from Temporary Chats is retained for up to 72 hours.
- Rollout starts today and will expand over the coming weeks.
Keep Activity setting
- Gemini Apps Activity will be renamed to Keep Activity in the coming weeks.
- When Keep Activity is on, a sample of future uploads - such as files and photos - may be used to improve Google services.
- If Gemini Apps Activity is currently off, Keep Activity will remain off after the rename.
- Keep Activity can be turned off at any time. Temporary Chats offer an option for unsaved conversations.
Background Context
Gemini Apps Activity has controlled whether prompts and responses are saved to a Google Account. Google says the rename to Keep Activity will not change existing off states, and sampling of uploads applies only when the setting is on. Personalization from past chats debuts on Gemini 2.5 Pro, with a phased rollout to additional models and regions. Temporary Chats are introduced alongside these updates.
