Shared DeepSeek chats are being indexed by Google and could become accessible to anyone through search. Following his unexpected discovery, the researcher expressed frustration that this potentially dangerous mechanism has still not been addressed.
The issue was discovered by chance by Peec AI GEO researcher David Konitzny while testing DeepSeek over the weekend.
According to him, Google is currently indexing pages from DeepSeek’s /share/ directory (chat.deepseek.com/share), where the platform stores chats that users have chosen to share. Using the site: search operator, these pages can be easily found through Google.
“This is exactly the kind of leak many of us believed the industry had learned to prevent after the incidents of 2024. Apparently not,” Konitzny wrote in a LinkedIn post.
What is particularly concerning is that the issue appears to have existed for quite some time. Discussions about it can be found on Reddit dating back to 2025.
DeepSeek allows users to create public links to chats using the Share button in the conversation interface.
Before generating a link, users can choose which prompts and responses to include. DeepSeek then displays a notice stating that the conversation can be viewed by “anyone with the link.”
However, as Konitzny points out, the warning makes no mention that the link itself may be indexed by search engines.
“In practice, this means that ‘anyone’ may include not only the people you intentionally shared the link with, but also anyone who discovers it through a search engine,” he explained.
Users can delete shared links at any time through the platform’s settings. However, the researcher believes that few people ever return to those settings after sharing a conversation once.
When searching Google for site:chat.deepseek.com/share, the search engine reports that it is displaying only the most relevant results because many similar pages have also been indexed.
The researcher then repeated the search and asked Google to display the omitted results. According to him, the expanded search revealed a significant number of publicly accessible shared chat pages.
After examining the browser’s developer tools, Konitzny also found that fields such as inserted_at reveal when a conversation was created. Other metadata provides insight into how DeepSeek processed individual prompts. This adds to the list of potentially sensitive information from shared chats that could end up directly in Google’s search results.
Although the issue may seem minor at first glance, the researcher warns that this unintended data exposure poses real privacy risks.
Even when users deliberately create public links, they may not expect those pages to be indexed by search engines.
As a result, a conversation originally shared only with a colleague or friend could later become accessible to anyone searching for related terms or browsing indexed pages.
Depending on the content of those chats, they may contain personal information, business plans, source code, confidential documents, or internal discussions.
If your shared chats have appeared in search results, the best course of action is to delete the shared links.
To do this in DeepSeek:
Open Settings.
Go to Data.
Select Shared Links → Manage.
Delete any shared links you no longer need.
