Hi, welcome to Spider ID. 🙂 This looks like a False Black Widow (Steatoda grossa).

They’re not aggressive and are unlikely to bite except in self defense if pressed up against the skin. My understanding is that their venom is similar to but much less potent to that of a Black Widow. You likely wouldn’t suffer any serious side effects but everyone’s immune system is different.
