Tap "Download the app" on your phone. If Chrome asks whether to keep the file, tap Download anyway.
Open the downloaded file (Safubi-Android.apk). Android asks to allow installs from this source - tap Settings, switch on Allow from this source, then go back.
Tap Install. If Google Play Protect says the app is unknown, tap More details → Install anyway. This shows for apps installed outside Google Play; Safubi will be on Google Play soon.
Open Safubi, create your account or sign in, and tap the big button. Allow the VPN connection when Android asks.
