Security question

Hello everyone!

I have a question about security of using Nextcloud and android app.

Does Nextcloud/android app transfers any data to external servers?
Or nextcloud android app connects only with my Nextcloud server? Therefore data transfers only within my network?

How can I check that?

Thanks for your answer!

it’s source is on github

As far as I know ( I don’t know much ) it doesn’t connect to other servers.

You can eighter read the source or grab tcp/ip package on you’re network to investigate.

It maybe connect to other servers to get the community info under settings.
