They released the source for their Android and their IOS app.
E2EE doesn’t mean servers are not used for storage, it only means servers can’t see message contents.
Note that this doesn’t mean that Olvid uses no servers (it does). It means that you do not have to trust them: your privacy is ensured by cryptographic protocols running on the client-side (i.e., on your device), and these protocols assume that the servers were compromised from day one. Even then, your privacy is ensured blush.
