Install the APK
Android calls this "installing from unknown sources". It is safe when the file comes from the official release page and the checksum matches.
Go to github.com/viroaryan/arivna-browser-releases/releases. Under the newest release, open Assets and tap the .apk file to download it.
Recommended. Compare the file's SHA-256 with the one printed in the release notes. How to check it.
Open the downloaded file. Android will ask you to allow installs from the app you used to open it. Tap Settings, turn on Allow from this source, then go back. The exact words vary by phone maker.
Tap Install. Google Play Protect may offer to scan the app or show a warning, because Arivna is not on Google Play yet. You can let it scan.
To open every link in Arivna: Android Settings → Apps → Default apps → Browser app, then pick Arivna. You can turn "Allow from this source" off again afterwards.
Verify the download
A checksum is a fingerprint of the file. If the one you calculate matches the one on the release page exactly, your APK is the file we published, unchanged.
Expected SHA-256 for version 1.0.0
050c18063aa6c916107d18bf508152f76a42e7ae4e13ce725474c180ab5819b5The commands below use the file name of version 1.0.0; change it if you downloaded another version. The result is 64 letters and digits; compare all of them with the SHA-256 in the release notes. Capital or small letters do not matter.

If the checksum does not match, do not install the file. Delete it, download it again from the official releases page, and if it still does not match, write to us at contactus@arivna.com.
Updates
Shield downloads fresh lists once a day, so blocking stays current without a new app version.
To hear about new versions, follow the releases page (on GitHub: Watch → Custom → Releases) or read the changelog. Install the newer APK over the old one; your tabs, bookmarks and settings stay.
Android only installs an update over an app signed with the same key. If the Play version is signed differently from your APK, Android will ask you to uninstall the APK first, which removes Arivna's data on the phone. We will say on the changelog when this applies.
Arivna is open source. You can read the code and build it yourself from github.com/viroaryan/arivna-browser; the build steps are in its README.
The FAQ covers permissions, data and what Arivna does not do.
