Whirlpool is a coinjoin implementation, run by Samourai, which is accessible via Sparrow. You can read more about it here: https://sparrowwallet.com/docs/mixing-whirlpool.html. Essentially, you pay a small fee and then coordinate with other users to create transactions which send the same amount of bitcoin you put in back to you, but in a way which obfuscates which bitcoin actually belong to you. If you are interested in anonymizing your bitcoin so entities such as centralized exchanges and blockchain analysis companies cannot trace it, then you could look in to this. If you do plan to use Whirlpool, make sure you also connect to the coordinator via Tor (explained in the link I just shared).
