"Device characteristics and device software. What you're doing on your device, like 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 you've shared through your device settings (like GPS location). Information about the network you connect your device to."

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

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

Meta collects location data through GPS, IP address, and network information, and uses it across multiple purposes including ad personalization, analytics, and sharing with third parties.

"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."

While Meta says they'll notify users of material changes, the framing implies continued use constitutes acceptance of new terms, with no mechanism for consenting to specific changes.

"Here's more detail about who we share information with: Partners — Advertisers and Audience Network publishers, Partners who use our analytics services, Partners who offer goods or services on our Products and commerce services platform, Integrated partners. Vendors — Measurement vendors, Marketing vendors, Service providers. Third parties — External researchers, AI integrations, Other third parties."

Meta shares user data with a very broad set of third parties including advertisers, analytics partners, measurement vendors, marketing vendors, external researchers, and AI integrations.

"We keep information as long as we need it to provide our Products, comply with legal obligations or protect our or other's interests. We decide how long we need information on a case-by-case basis. Here's what we consider when we decide: If we need it to operate or provide our Products... How long we need to retain the information to comply with certain legal obligations... In some instances and for specific reasons, we'll keep information for an extended period of time."

Meta provides no specific deletion timelines, decides retention on a case-by-case basis, and reserves the right to keep data for extended periods, effectively allowing indefinite retention.

"For some of these purposes, we use information across our Products and across your devices. The information we use for these purposes is automatically processed by our systems. Sharing of information across the Meta Companies: To provide a seamless, consistent and richer, innovative experience across the Meta Company Products to enable cross app interactions, sharing, viewing and engaging with content."

Meta tracks users across all Meta products (Facebook, Instagram, WhatsApp, etc.), across devices, and uses device identifiers and cookies to build unified profiles for ad targeting and personalization.
