A modern smartphone has a trove of incredibly sensitive information—from photos of your children to a list of all your daily activities to the websites you love to visit. The only reason we can entrust this data to smartphones is because they are built to be secure.

But a misguided California bill could jeopardize that basic security we’ve come to rely on.

A.B. 1681 would require all manufacturers and operating system providers to be able to decrypt smartphones sold in California or risk being fined. By impacting every smartphone user in the state, this bill would affect tens of millions of people who have done nothing wrong.

Please sign our petition against this terrible bill. We’ll deliver this petition to lawmakers in the state with your name and address.
