It’s already a year since it was on playstore. I don’t use the app since I don’t need it yet so Captain Nemo or Sammy can best answer your question. Just message them here in the forum or email and if they have the time, they will reply to you.
There are also other free VPN apps on google playstore or i store (if using an apple device) which may be useful or effective for you. You can choose, download and try them out.
