What the vulnerability does

01Description

HelloTalk through 3.4.1 stores full-precision GPS coordinates even when the user had intended to share only a country or city. Furthermore, these coordinates are placed into a database on the client of other users. (The client side was changed in 2019 to encrypt that database.)
