What happened

Google acknowledged a technical glitch in its Gemini AI platform that caused chat histories to disappear unexpectedly for users worldwide.

The problem affected Gemini's mobile app, website, and the Gemini applications page within Google accounts. One user reported the issue lasted four consecutive days, while another user's chats disappeared on 19 February and returned automatically after three days.

Reported impact

The deletion affected the chat history feature, which users rely on to return to previous conversations and search archived exchanges for information and answers.

One paid Google AI Pro subscriber expressed hope that the company would compensate users for the service disruption period.

Governance controls

Google published a statement on its official blog confirming awareness of the problem affecting a limited number of users and committed to restoring all deleted conversations through an upcoming update.

Google acknowledged that the experience may be disruptive but stated its teams were working to restore the service to normal as quickly as possible.
