Can employees use WhatsApp for work only on company phones?
You can allow or block WhatsApp for a group, or allow it only during set hours using a schedule window. Skie cannot separate work chats from personal chats inside WhatsApp, because it does not read messages. A separate approved messaging app for work is the cleaner choice.
WhatsApp is how many teams in India actually talk: dispatch groups, customer follow-ups, photos of delivered goods. Banning it often means staff use it on their personal phones instead, where you have no control at all.
In Skie, WhatsApp is just an app on the list. Add it to the group's list and it works. Leave it off and it does not. You can also allow it in certain windows: a schedule with days, start, end and an allowed app set means WhatsApp can be on during shift hours and off at night. Hostel night mode style rules exist for exactly this kind of switch.
What Skie cannot do is look inside the app. It does not read private messages, call logs or record audio or video, and it has no hidden mode. So it cannot tell whether a given chat is about work. If you want that kind of separation, the answer is policy and tool choice: ask staff to use a business messaging app, or a WhatsApp account used only for work, on the company phone.
Optional switches help at the edges. SMS and outgoing calls can be disabled. Screenshots can be disabled. USB file transfer is off by default, and cloud backup can be turned off, so chat content does not flow to a personal cloud account.
A practical tip: put the rule in your acceptable-use note, along with a plain line that the company does not read employee chats and cannot.
