The 2019 Ranking Digital Rights Corporate Accountability Index evaluated 24 of the world's most powerful internet, mobile and telecommunications companies on their disclosed commitments and policies affecting freedom of expression and privacy of internet users across the world.

Now in its fourth iteration, the RDR Index has continued to expand each year. Beginning in 2015, RDR evaluated 16 internet and telecommunications companies using 31 indicators. Then in 2017, RDR evaluated 22 telecommunications, mobile and internet companies using a revised methodology made up of 35 indicators. Now the fourth edition of the RDR Index has grown to include two more companies, for a total of 24, and RDR is planning to once again revise its methodology and add companies for the next edition of the ranking, scheduled for 2021. 

As a note: with the revision of Ranking Digitial Rights' methodology in 2017, the 2015 scores are not easily comparable to the second, third and fourth rankings. 

The Privacy category contains 18 indicators that measure corporate commitments and disclosure of policies affecting users' privacy. Indicators in this category evaluate whether the company's policies and commitments demonstrate concrete ways in which it respects the right to privacy of users, as articulated in the Universal Declaration of Human Rights, the International Covenant on Civil and Political Rights, and other international human rights instruments. The company's disclosed policies should demonstrate how it works to avoid contributing to actions that may interfere with users' privacy, except where such actions are lawful, proportionate, and for a justifiable purpose. They must also demonstrate a strong commitment to protect and defend users' digital security. Companies that perform well on these indicators demonstrate a strong public commitment to transparency not only in terms of how they respond to government and private requests for user information, but also how they determine, communicate, and enforce private rules and commercial practices that affect users' privacy.
