When Google first unveiled its Allo messaging app, the company said it would not keep a log of chats you have with people when in incognito mode. The company released Allo for iOS and Android users last night, and it seems it is reneging on some of those promises. The Verge reports:The version of Allo rolling out today will store all non-incognito messages by default -- a clear change from Google's earlier statements that the app would only store messages transiently and in non-identifiable form. The records will now persist until the user actively deletes them, giving Google default access to a full history of conversations in the app. Users can also avoid the logging by using Alo's Incognito Mode, which is still fully end-to-end encrypted and unchanged from the initial announcement. Like Hangouts and Gmail, Allo messages will still be encrypted between the device and Google servers, and stored on servers using encryption that leaves the messages accessible to Google's algorithms. According to Google, the change was made to improve the Allo assistant's smart reply feature, which generates suggested responses to a given conversation. Like most machine learning systems, the smart replies work better with more data. As the Allo team tested those replies, they decided the performance boost from permanently stored messages was worth giving up privacy benefits of transient storage.
