Where is v27 mobile phone privacy encryption?

Hello; usually it is in the security management, but I usually use Tencent Mobile Manager to encrypt privacy. It has a safe and reliable private protection space, and can add private photos, text messages, videos, etc. to private protection. The space is encrypted; the privacy protection problem of the mobile phone is also solved. At present, the vast majority of users are using the privacy space function of Tencent Mobile Manager to encrypt private information such as call records, photos, videos, text messages and files. It can also detect viruses, speed up mobile phones, etc. Thank you and hope to adopt
