I had to uninstall it
It looks nice and useful but has several cave outs: 1. The VPN is compulsory to use, otherwise it doesn’t work. Moreover it doesn’t hide your IP or location. 2. Some internet providers don’t allow the use of VPN, I found it out at a hotel in France. 3. It seems to me that the data consumption shown by the app is exaggerated. 4. When I offloaded the app, suddenly I was disconnected from my own WiFi even when all the other computers were connected. Airplane mode off-on, password reset, iPhone reset and so didn’t solve the problem. Then I uninstalled the app and suddenly the wifi connection was fixed!
