FAQ

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 Windows Credential Manager, the OS 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.

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?

Windows first. The engine is platform-agnostic, so both are future options, but there is no committed date.
