Installation and checksums
Android
Open the APK and allow installation for the downloader or file manager you use. Stop and contact us if signatures conflict; do not uninstall first.
macOS
Open the DMG, drag Nearvia.app into Applications, eject the image, then launch the installed app.
Windows
Extract the entire ZIP into a writable directory. Open Nearvia/sovkit.exe; keep its DLLs, data directory and license files.
Verification
Compare the full SHA-256. Source code ZIP/TAR archives are not installers. Stop and verify unexpected source, signature or file warnings; keep system protections enabled.

Connect and use

Install on both devices and connect to the same local network. Find the peer under Nearby, compare and confirm the security code on both devices, then send messages or files.

If a device is missing, check network access, app permissions and guest-network isolation. Delivery needs an available connection; continuous background operation or delivery is not guaranteed.

No service account is required. Contacts and conversations stay on your device; received files are outside database encryption.

Communication is provided by SovKit. Developer resources →
