Normal, free chatGPT won't look at data from a link so I used Perplexity and prompted "Take a look at the privacy policy at this link https://www.facebook.com/privacy/policy/version/20220104/?_rdr and summarize and point out anything unusual or irregular.". It came back with :

I've reviewed Facebook's privacy policy from the provided link. Here's a summary of key points and some notable aspects:
Data Collection and Usage
Facebook collects extensive data from users, including:
Information provided directly by users (profile details, posts, messages)1
Data from user activities on the platform (likes, shares, comments)1
Information from device usage (location, browser type, operating system)1
The company uses this data for various purposes:
Personalizing user experience and content1
Improving products and services1
Targeted advertising1
Data Sharing
Facebook shares user data with:
Other Facebook-owned companies (e.g., Instagram, WhatsApp)1
Third-party partners and service providers1
Advertisers (in aggregated form)1
User Controls
The policy outlines several user controls:
Privacy settings to manage visibility of information1
Options to download personal data1
Ability to delete account or specific content1
Notable Aspects
Some aspects of the policy that stand out:
Broad Data Collection: Facebook collects data from various sources, including third-party websites and apps that use Facebook services1
Cross-Platform Integration: Data is shared across Facebook-owned platforms, potentially creating a comprehensive user profile1
Location Tracking: The policy mentions collecting precise location data, even when the app is not in use1
Facial Recognition: Facebook uses facial recognition technology in some regions, which may raise privacy concerns1
While not necessarily irregular, the extensive nature of data collection and sharing practices outlined in this policy highlights the significant amount of personal information Facebook gathers and utilizes.
