Even if a user includes personal details within a chat, we cannot verify whether such statements are accurate or whether they are made by the actual person described. As a result, this information is not sufficient for us to properly identify an individual user. While identifiability is limited, personal data may still appear in chats provided by the users and is processed accordingly.

To achieve these goals, we need access to the complete information described in this policy, since aggregated data alone would not allow us to perform accurate analysis.
