HB Wallet does not store any information of our users. It includes private key and passphrase. Therefore, even if our server is hacked, information of our users is still safe.
Also, other people can use your passphrase and private key to access your account. Therefore, DO NOT SHOW ANYONE YOUR PASSPHRASE AND YOUR PRIVATE KEY! It is best to write them down and keep at a safe place, so you can restore your wallet if anything happens in the future!
