Who develops Sogou Input Method?
It is developed by Beijing Sogou Technology, with the iOS and Android package com.sohu.inputmethod.sogou. Sogou later joined Tencent, so it is now part of the Tencent group; the simplest check is the official domain and package.
Did Tencent acquire Sogou?
Yes. Sogou became part of Tencent in 2021, making Sogou Input Method a Tencent product. This does not affect daily use; just download the official build from sogouinputmethod.com.
How do I tell official from fake?
Trust the main domain sogouinputmethod.com and the package com.sohu.inputmethod.sogou; sites like app-sogou.cn or web-sogou.com with a high-speed downloader are fakes, and official statements follow the site.

How do I turn off all the ads?
On PC, right-click the icon, open Properties and disable hot-search, info and push items; on mobile, open More Settings from the S logo and turn off promotion and hot-novel toggles. Operate only in the official build.
How do I stop pushes and floating windows?
Turn off hot-search, message and floating-window pushes in Properties or Input Settings, and the matching toggles in mobile notification settings; how much you can disable varies by version.
Does it push you to pay?
Core typing is free, but some premium skins and extras show promotions. Turn off the related pushes in settings and buy only as needed; any pay-before-download or pay-to-type page is a fake site.
Can I turn off personalization and improvement?
Yes. Disable personalized recommendations and the user-experience improvement program in settings to reduce data use based on your input; these are optional and do not affect core typing.

Where do I see and verify official statements?
Follow the site sogouinputmethod.com and in-app notices, and for security events rely on vendors like Trend Micro and official statements; verify rumors against the site rather than third-party pages.
