In this report, we analyze the Windows, Android, and iOS versions of Tencent’s Sogou Input Method, the most popular Chinese-language input method in China. Our analysis found serious vulnerabilities in the app’s custom encryption system and how it encrypts sensitive data. These vulnerabilities could allow a network eavesdropper to decrypt sensitive communications sent by the app, including revealing all keystrokes being typed by the user. Following our disclosure of these vulnerabilities, Sogou released updated versions of the app that identified all of the issues we disclosed.
Vulnerabilities in Sogou Keyboard encryption expose keypresses to network eavesdropping.
It probably doesn’t though. Obviously it’s closed source making it harder to tell what’s actually happening, but there’s nothing stopping security analysts from looking at network usage and such. I would imagine that Google doesn’t install a keylogger on every Android phone, not out of the goodness of their hearts, but because they don’t want the bad publicity and lawsuits when it would inevitably be discovered.
they do collect usage stats by default though.
which include typed sentences passed through their ai model and words usage counts.
it can all be turned off and gboard seems to respect these options. it doesn’t access online services unless requested with these options off.
If you mean by “collect usage stats” train their AI model on-device and send the training result to Google, then yes. If you mean that the actual words get sent to Google’s servers, then no. There was a study shared recently that looked into this. Only metadata about what’s typed is sent. That’s not nothing of course, but it’s not what Tencent does at all.
Thank you for this. This is much more reasonable of a privacy critique than falsely claiming Google is using a keylogger. I heard Grammarly was doing something similar and deleted my account. I’m changed the settings, but will continue using Gboard because I like the combined emojis.

E: Found it.
