How secure is My algo wallet?

More technical answer the better..... Lot's of crypto malware floating around and have been seeing a lot of people losing funds after accessing and downloading malicious software and/or clicking on inappropriate links. With myalgo wallet is the information ever stored on your computer to access your private keys/25 word passphrase? Also even if someone was watching my computer and had my password to sign transactions it wouldn't help because that is a local authorization for sending transactions? correct? Lastly in my mind the only way they could access my account is if I stored my private key on my computer or they were watching my screen as i either input 25 word phrase or I am viewing it. Is that assumption correct? Thanks for any and all input.
