Questions people ask.

For transfer, yes; for storage and sync, no. Privatta has no server and stores nothing, so there is nothing to host. If what you need from Nextcloud is a shared library everyone syncs, Privatta does not replace it.

With Nextcloud, your server keeps a copy of every file in it, which is the point of a file server. With Privatta, files stay on the computers they are on, and nothing keeps a copy in between.

Yes. The file goes directly from one copy of Privatta to another, so it runs on both ends. The recipient uses the Windows app (Linux is to follow); the Android app is not available at the moment.

Yes. The file comes straight from your machine, so Privatta has to be running on your side while the other person takes it. If that is impractical for a particular job, a link-based service is the better fit for that job.

No. Over the internet, a small open-source relay introduces the two machines with a key that works once, then steps aside, and the file travels directly between them, encrypted. On a local network no outside server is involved at all. You can run your own copy of the relay.
