Is Sogou Input Method safe?
If you install the official build from sogouinputmethod.com, everyday typing is generally fine. The real risks are fake download sites and the old, unmaintained Zhuyin build whose update server was reportedly poisoned in 2025.
Does it upload what I type?
Plain local typing stays on the device, but cloud input and suggestions send text to servers to improve accuracy. Turn off cloud input to reduce uploads, and on iPhone leaving Full Access off also limits connectivity.
Is typing bank passwords recorded?
The official build types locally, but to be safe, switch to the system keyboard for bank passwords and codes (long-press the globe key on iPhone) and avoid granting unnecessary permissions.

Does Sogou really monitor users?
The official app is a mainstream product; its cloud features upload some text for service, which differs from malicious monitoring. The confirmed attack targeted the abandoned old Zhuyin build, not the current app.
What does the privacy policy collect?
Sogou states it collects data needed to provide service, such as online-input data; see the current policy in-app or on the site, and turn off cloud input and personalization to reduce uploads.
Will data go to mainland servers overseas?
Cloud features send some input to Sogou servers; if concerned, turn off cloud input, skip login and skip Full Access. Taiwan users should avoid the old Zhuyin build and use only the official Pinyin build.
How do I minimize uploads?
Turn off cloud input for local candidates, skip iPhone Full Access, disable personalization and the improvement program, switch to the system keyboard for sensitive input, and install only from sogouinputmethod.com.

Are clipboard and input history safe?
Clipboard and input history are local, but cloud sync uploads some data for cross-device use; disable sync if not needed, avoid leaving sensitive content in the clipboard, and clear history regularly.
