Most of us don’t – and that means privacy policies are missing the mark.
One of the fundamental purposes of privacy policies is to enable people to make informed decisions. But privacy policies are surprisingly ineffective at informing consumers, as Rebecca Balebako, Lorrie Cranor and I analyse in our research.
With our research, we propose a better way that would make privacy notices clearer and easier to follow. We aim to share our research and insights with other people and organisations working on innovative approaches to online transparency, and are happy for our work to be a part of the TTC Labs.
A 2008 study by Lorrie Cranor and Aleecia McDonald estimated that it would take 244 hours a year for the typical American internet user to read the privacy policies of all websites he or she visits – and that was before everyone carried smartphones with dozens of apps, before cloud services, and before Internet of Things technologies.
Even people who read privacy policies struggle to understand them, because they often require college-level reading skills. Privacy policies frequently cover multiple services offered by a company, resulting in vague statements that make it difficult to find concrete information about which personal information is collected and how it is used.
Out of context
Privacy policies are increasingly separated from users’ actual interactions with a system. Websites link to policies at the bottom of pages, mobile apps link to them in the app store and the policy of your smart speaker or fitness tracker is likely posted somewhere on the company’s website.
Few privacy policies provide consumers with any choices besides not using the service at all. Companies may also change their privacy policies anytime. Not accepting the updated policy – if consumers are even asked to acknowledge the change – may stop your gadget from working or result in termination of the account.
Academics, regulators and governments have called for more usable privacy notices and solutions. Europe’s General Data Protection Regulation, which takes effect in May 2018, imposes strict requirements on privacy notices. Notices must be in 'concise, transparent, intelligible and easily accessible form, using clear and plain language.' Most privacy notices today do not meet these requirements. How can we change that?
Towards a better way: Refocusing on the consumer
Privacy policies serve different functions for consumers, companies and regulators – and to be effective, they have to reconcile all three. Companies use privacy policies to demonstrate compliance with legal and regulatory notice requirements, and to limit liability. Regulators use them to investigate and enforce compliance with regulations. People should be able to rely on them for meaningful information about their privacy choices. But at the moment, people’s needs are getting lost.

Privacy information and choices in context
A casual browser certainly needs some information, like how the site handles their IP address, whether their browsing activity will be shared with advertisers and whether they can opt out of interest-based ads.
But a user who engages more deeply with a site needs more information to make meaningful choices, like whether or not she wants her email address to be shared with outside marketing companies. An additional short privacy notice could provide the relevant information when entering her email address and then offer the option of checking a box at the relevant point.

Notices can be made simpler by focusing particularly on unexpected or surprising types of data collection or sharing.
In another study, we learned that most people know their fitness tracker counts steps – so they didn’t really need a privacy notice to tell them that. But they did not expect their data to be collected, aggregated and shared with third parties. Customers should be asked for permission to do this, and allowed to restrict sharing or opt out entirely when information leaves the original context of collection.

Most importantly, companies should test new privacy notices with users, to ensure final versions are understandable and not misleading, and that choices are meaningful.
Augmenting privacy policies
Conversational Privacy Interface | Dublin Design Jam | November 2017
Systems like this give people usable information and real choices. And they encourage app developers to communicate better with users about privacy. If we can expand this model, everyone could have privacy policies that are clear, easy to understand and really meaningful for both users and software designers.
