Can you please allow to setup Brave Reward also on an android device without google services? I cannot see a reason why it should need it and please don´t say security. Also you could allow to download apk on your webside.
APK is available on GitHub.
The exact URL for the latest stable version for Android is https://github.com/brave/brave-browser/releases/tag/v1.10.99
Please note, you may need to manually update it. Check brave.com/latest for the information about the latest version.
And when the new version is available, you just need to edit the version number from the first link above –
v1.10.99 – to the new version.
For now, Brave use Google’s SafetyNet API to test device integrity. It may change in the future.
