FAQ

When is the release?

Soon. The first public build is in the final stretch, and the fastest way to know the moment it ships is the notification list: one email on release day, nothing else.

Where can I ask questions or follow development?

The Varv Discord is where development updates land first and questions get answered. Bug reports and feature ideas are welcome there too, before and after release.

Is it free?

The core client is free: every provider, the transfer queue, search, zip browsing and the S3 management editors. A paid Pro tier with power workflows (folder sync, copying between accounts, CLI) is planned; see pricing.

Does it phone home?

No. There is no telemetry and no account system. The app talks to your storage endpoints and nothing else.

Where are my credentials stored?

In your operating system’s keychain: Windows Credential Manager or the macOS Keychain. They are never written to plaintext config files.

What happens if the app crashes mid-transfer?

The transfer queue is journaled to SQLite. On restart the queue restores and resumes where it stopped, including partially uploaded multipart files. Finished parts are not re-uploaded.

Which providers work?

Amazon S3 and any S3 compatible service (Cloudflare R2, MinIO, Backblaze B2, Wasabi, DigitalOcean Spaces, Hetzner, Scaleway, Storj, Tigris, custom endpoints), plus FTP, FTPS and SFTP. Web server directory listings (Apache, nginx, IIS, lighttpd, Caddy) can be browsed read only too.

Can my storage provider read my files?

With normal uploads, technically yes: the provider stores exactly what you send. If you would rather they could not, turn on encryption for the connection. Files and names are then scrambled on your machine before upload, in the same format rclone crypt uses, so nothing readable ever leaves your computer.

Can it really browse zip files without downloading them?

Yes. Zip archives on any backend open in place, including nested archives. Extracting a single file streams just that file’s bytes.

macOS or Linux?

Both Windows and macOS, from the first release. Linux is a future option with no committed date. Progress lands first in the Discord.
