I'm a Monero dilettante, but my understanding is that this is not the case - your private key (or some derivative of it) is needed in order to unmask transactions on the blockchain that involve you, so others can't see what you've been up to. See below:

"When you send funds to someone’s public address, what happens is that you actually send the funds to a randomly created brand new one-time destination address. This means that the public record does not contain any mention that funds were received to the recipient’s public address.

For the same reason, the funds that you are sending were not associated with your own public address either in the public record. Therefore, when you send these funds, the public record will not show that the funds originated from your public address and will not show that the funds were sent to the recipient’s public address."
