Passcodes and Passwords
Some smartphone creators, like OnePlus, really do collect your passcodes or passwords and have even gotten in trouble for it. Their excuse is that they want to collect data on how customers behave, like how often they are unlocking their phones or how often they are setting passwords. As excuses go, it’s not great, and customers were understandably displeased.
While Apple doesn’t mention if it uses your passcode activity or not, the company does make it clear that it neither collects nor stores biometric info like your face or fingerprint, and even iOS can’t technically access that data once it’s created.
