In Bitcoin parlance, an extended key, also known as a BIP32 or HD Wallet key, is a master key that can be used to derive multiple bitcoin addresses.
The public portion of the key will be stored and used by CoinOS to generate a separate receiving address for every payment to your account. This will preserve your and your customers' privacy by preventing people from seeing or tracking transactions to your account other than their own.
The private portion of the key will be generated here but we will not store it after you close this window. You will be responsible for saving it and making copies of it. If you lose access to it, any funds sent to your account will be unspendable. If someone other than you gains access to it, your funds could be stolen.
