Lately, many Google Gemini users are discovering that their chat history disappears without warning. Conversations that should have persisted—covering projects, reminders, or past prompts—are vanishing, leaving users frustrated and worried about losing important work.
Some users say they’ve lost up to four days’ worth of chats. The problem happens both in the browser and in the mobile app. It does not appear to affect everyone, but the risk seems significant enough that many are cautioning others to backup their conversations.
What Might Be Causing Chats to Disappear
Based on what users have observed:
-
Chats sometimes disappear from the “Recent” or “Pinned” views even though they still appear in Gemini’s activity logs.
-
If the “Keep Activity” or equivalent setting is turned off, chats may not be preserved in recent/pinned lists.
-
Bugs or delays in syncing between devices seem likely; closing the browser tab or app and reopening may show different results.
-
Auto-save or “history” features may not reliably capture every message, especially recent inputs or responses, when the app is closed or the session expires.
How You Can Protect Your Gemini Conversations
Until there’s an official fix, there are several simple precautions you can take:
-
Enable Activity / Keep Activity
Make sure your settings allow Gemini to “keep” your activity. That helps ensure your chats are logged and stored. (If you turn that off, you risk losing recent history or having chat drops.) -
Use Gemini Apps Activity / Equivalent Feature
Check whether your account has a way to view saved chat history via an activity log. If yes, regularly check it to verify your conversations are still being saved. -
Save Important Chats Manually
For threads you care about—projects, content, studies—copy the text into a document you control (e.g. Google Docs, a note app, or any cloud backup). That way you have a copy even if Gemini drops it. -
Use Different Devices or Interfaces
Sometimes browser vs app results differ. Checking chats on the web version occasionally can catch if a conversation disappeared in the app. -
Report Missing Chats
If portions of a chat actually disappear (in app or web), use Google’s support tools to report a bug. The more reports they receive, the likelier it is they’ll push a fix.
What Users Should Expect Next
-
A proper fix from Google is probably coming, especially given how many reports have piled up.
-
Google may improve syncing, bug fixes around saving recent messages, or changes in how the “Keep Activity” setting works.
-
Future updates might include auto-save improvements or warnings when chats might be at risk of not being saved.
