Tivifyer is a player that includes no content, but Amazon's policy makes no distinction. That is why we offer direct installation, the same method thousands of apps use on Fire TV.
Yes. We sign the file ourselves with the same key as the Google Play version, and you can check the SHA-256 fingerprint on this page. Only download Tivifyer from tivifyer.com.
When we publish a new version, Tivifyer will tell you when you open it. Come back to this page, type the same code in Downloader and it installs over the old one without losing your playlists or settings.
The permission from step 2 is missing. Go to Settings → My Fire TV → Developer options → Install unknown apps and turn Downloader on. On older Fire OS versions the option is called "Apps from unknown sources".
None of this is needed there: Tivifyer is on Google Play.
