• Title: Privacy Policies Across the Ages: Content and Readability of Privacy Policies 1996--2021
• Authors: Isabel Wagner
• Abstract summary: We analyze the 25-year history of privacy policies using methods from transparency research, machine learning, and natural language processing. We collect a large-scale longitudinal corpus of privacy policies from 1996 to 2021. Our results show that policies are getting longer and harder to read, especially after new regulations take effect.

• Abstract: It is well-known that most users do not read privacy policies, but almost all users tick the box to agree with them. In this paper, we analyze the 25-year history of privacy policies using methods from transparency research, machine learning, and natural language processing. Specifically, we collect a large-scale longitudinal corpus of privacy policies from 1996 to 2021 and analyze the length and readability of privacy policies as well as their content in terms of the data practices they describe, the rights they grant to users, and the rights they reserve for their organizations. We pay particular attention to changes in response to recent privacy regulations such as the GDPR and CCPA. Our results show that policies are getting longer and harder to read, especially after new regulations take effect, and we find a range of concerning data practices. Our results allow us to speculate why privacy policies are rarely read and propose changes that would make privacy policies serve their readers instead of their writers.

• The Privacy Policy Permission Model: A Unified View of Privacy Policies [0.5371337604556311]
  A privacy policy is a set of statements that specifies how an organization gathers, uses, discloses, and maintains a client's data. Most privacy policies lack a clear, complete explanation of how data providers' information is used. We propose a modeling methodology, called the Privacy Policy Permission Model (PPPM), that provides a uniform, easy-to-understand representation of privacy policies.

We also collect a large corpus of privacy policies to enable privacy policy domain-specific language model pre-training. We demonstrate that domain-specific continual pre-training offers performance improvements across all tasks.

  We consider partial differential privacy (DP), which allows quantifying the privacy guarantee on a per-attribute basis. In this work, we study several basic data analysis and learning tasks, and design algorithms whose per-attribute privacy parameter is smaller that the best possible privacy parameter for the entire record of a person.

  Privacy policies are often written in extensive legal jargon that is difficult to understand. We aim to bridge that gap by providing a framework that analyzes privacy policies in light of various data protection laws. By using such a tool, users would be better equipped to understand how their personal data is managed.

Our data indicate that self-regulation for first-party websites has stagnated, while self-regulation for third parties has increased but is dominated by online advertising trade associations.
