"Device characteristics and device software. What you're doing on your device, such as whether our app is in the foreground or if your mouse is moving (which can help tell humans from bots). Identifiers that tell your device apart from other users'. Device signals. Information that you've shared through your device settings (e.g. GPS location). Information about the network that you connect your device to."

Meta collects extensive device data including mouse movements, device signals, unique identifiers, GPS location, network information, and camera roll contents — far beyond what's needed for core social networking functionality.

"Information that you've shared through your device settings (e.g. GPS location). Location-related information. Information about the network that you connect your device to, including your IP address. Information from cookies and similar technologies."

Meta collects location data through multiple methods including GPS, IP address, and network information, and uses it across nearly every processing purpose listed in the policy — from ad personalization to analytics to research.

"We'll notify you before we make material changes to this Policy. You'll have the opportunity to review the revised Policy before you choose to continue using our products."

Meta frames continued use of products as acceptance of revised policy terms. Users must either accept new terms or stop using the service, with no mechanism to negotiate or reject specific changes.

"We share the information that we collect, infrastructure, systems and technology with the other Meta Companies. We also process information that we receive about you from other Meta Companies, according to their terms and policies and as permitted by applicable law. Here's more detail about who we share information with: Partners, Advertisers and Audience Network publishers, Partners who use our analytics services, Vendors, Service providers, External researchers, AI integrations, Other third parties."

Meta shares user data with a sprawling ecosystem of partners, advertisers, analytics partners, vendors, researchers, AI integrations, and across all Meta Companies (including WhatsApp), creating extensive third-party data exposure.

"We keep information for as long as we need it to provide our products, comply with legal obligations or to protect our or other's interests. We decide how long we need information on a case-by-case basis. In some instances and for specific reasons, we'll keep information for an extended period of time."

Meta provides no specific retention timelines, instead using vague 'case-by-case' criteria and reserving the right to keep data for 'extended periods,' giving users no certainty about when their data will be deleted.

"For some of these purposes, we use information across our Products and across your devices. When we show you ads through Meta Audience Network when you visit other apps, our systems automatically process the information that we've collected and stored about you and others to identify you as a Meta Product user and tailor the ads that you see."

Meta tracks users across all Meta products, across devices, and across third-party apps via the Audience Network, building unified profiles that follow users throughout their digital activity both on and off Meta platforms.
