Yes it does, under: Can I (customer) cancel or opt out of this agreement to arbitrate?
"If you want to opt out, go to the Legal Agreements and Disclosures section of your chase.com or jpmorganonline.com profile or on Chase Mobile or JP Morgan Mobile."
On the lower left side bar of the desktop/full site in small print is the legal agreements and disclosures link. That page has the link for the Arbitration opt-out
Oh and let's be clear - Chase is an absolute trash bank. I have no idea why anyone would waste time with their retail deposit or savings products.
However Chase does offer some of the best travel Credit Card products in the US, the only one directly competing with them is Amex and they are not a great worldwide traveling card, Capitol One is close but not quite. Chases' customer service is a mixed bag, but it's on par or better than most of the competition (say, Citi, ugh).
