-snip- except maybe user created labels could be gone from your addresses/transactions, if you didn't create backup for that.
In that case, he can use "
Label Sync" plugin which also works in electrum-ravencoin although it's using the same server as Electrum.
Ref:

henrythebest If you want to use the plugin, simply enable it in "
Tools->Plugins->LabelSync".
Your labels should be safe and privately stored in the server since it's is encrypted with the hashes of your master public key and the master public key isn't sent to the server as well.
So it has no idea of your labels and xpub key.
