Colorado Gov. Jared Polis signed the state's privacy bill into law on Wednesday, according to a spokeswoman.
The signing, which comes after the state legislature passed the bill overwhelmingly last month, makes Colorado the third state with a digital privacy law on the books, after California and Virginia.
The law ups the stakes for companies hoping, despite little movement in Congress, that federal lawmakers will lay down a single set of standards and overrule a developing patchwork of divergent regulations.
The new law grants consumers rights "to opt out of the processing of their personal data," to obtain a copy they can bring to a rival service and to "access, correct, or delete the data," according to the legislature. It also bans data controllers from processing data in a way that would violate state or federal anti-discrimination laws.
