* While all the keys and transaction detection happens on the client, the server can learn what blocks contain your shielded transactions.
* The server also learns other metadata about you like your ip address etc...
* Also remember that t-addresses don't provide any privacy protection.
### Note Management
Zecwallet-Lite does automatic note and utxo management, which means it doesn't allow you to manually select which address to send outgoing transactions from. It follows these principles:
* Defaults to sending shielded transactions, even if you're sending to a transparent address
* Sapling funds need at least 5 confirmations before they can be spent
* Can select funds from multiple shielded addresses in the same transaction
* Will automatically shield your transparent funds at the first opportunity
* When sending an outgoing transaction to a shielded address, Zecwallet-Lite can decide to use the transaction to additionally shield your transparent funds (i.e., send your transparent funds to your own shielded address in the same transaction)
