Meta Portal

Meta receives data on its users from "third parties incl. advertisers and third-party data providers who have the rights to provide us with your information", whether users have Facebook account or not:
"Advertisers, app developers, and publishers can send us information through Meta Business Tools they use, including our social plug-ins (such as the Like button), Facebook Login, our APIs and SDKs, or the Meta pixel. These partners provide information about your activities off of our Products—including information about your device, websites you visit, purchases you make, the ads you see, and how you use their services—whether or not you have an account or are logged into our Products. For example, a game developer could use our API to tell us what games you play, or a business could tell us about a purchase you made in its store.We also receive information about your online and offline actions and purchases from third-party data providers who have the rights to provide us with your information."

Video call content is not used for advertisement: "Facebook does not listen to, view or keep the contents of your Portal video calls. This means nothing you say on a Portal video call is accessed by Facebook or used for advertising."

Lots of other data collected when using the Portal can be used for Facebook advertisement though: "Portal is integrated with some of your Messenger and Facebook experiences. When you use Portal, we process the same kinds of information as when you use Facebook products on your other devices. Some of this information, including the fact that you logged into your account or how often you use a feature or app, may be used to inform the ads you see across Facebook."

While Facebook is not sharing ads on Portal, third-party apps are. "We don’t show Facebook ads on Portal. However, you may see ads from some third-party apps on Portal (e.g., music partners) in the same way you’ll see ads from these services on other devices."

Facebook says it does not sell any of your information to anyone, and never will. However, it shares data with numerous third parties such as partners who use their analytics services, advertisers, measurement partners, partners offering goods and services in Facebook products, vendors and service providers, researchers and academics, law enforcement, and legal requests.

Facebook is using data to help third parties provide and measure advertisement: "We use the information we have (including your activity off our Products, such as the websites you visit and ads you see) to help advertisers and other partners measure the effectiveness and distribution of their ads and services, and understand the types of people who use their services and how people interact with their websites, apps, and services. Learn how we share information with these partners. "

Facebook says that it does not use voice data for targeted ads. However, the metadata about your Portal usage – how often you make video calls or use in-call apps or features – can be used to target you with advertisements across the Facebook advertisement network..

In addition, Facebook collects personal data from its partners. These partners provide information about your activities off Facebook — including information about your device, websites you visit, purchases you make, the ads you see, and how you use their services—whether or not you have a Facebook account or are logged into Facebook.

Facebook shares information it collects on Portal with independent apps and services that integrate with Portal. This may include information about a user’s Portal device, such as device name, IP address, and zip code, as well as other information to help them provide the services requested by the user (for example, the text and subject of their voice commands to the app, service or integration through “Hey Portal”). The information collected by these independent apps, services, or integrations is subject to their own terms and policies.

It is unclear if all users regardless of location can get their data deleted. Facebook mentions GDPR and CCPA right to delete data.

"We store data until it is no longer necessary to provide our services and Meta Products, or until your account is deleted - whichever comes first. This is a case-by-case determination that depends on things like the nature of the data, why it is collected and processed, and relevant legal or operational retention needs. For example, when you search for something on Facebook, you can access and delete that query from within your search history at any time, but the log of that search is deleted after 6 months. If you submit a copy of your government-issued ID for account verification purposes, we delete that copy 30 days after review, unless otherwise stated. Learn more about deletion of content you have shared and cookie data obtained through social plugins.

When you delete your account, we delete things you have posted, such as your photos and status updates, and you won't be able to recover that information later. Information that others have shared about you isn't part of your account and won't be deleted. If you don't want to delete your account but want to temporarily stop using the Products, you can deactivate your account instead. To delete your account at any time, please visit the Facebook Settings and Instagram Settings. "

Facebook Assistant activates when it hears “Hey Portal” and gives you a visual confirmation at the bottom of the screen. When your Portal hears the wake word, it will start to record your voice interaction and send it to Facebook servers in real-time to respond to your request. When you turn Portal’s microphone off, Portal won’t listen for the wake word, and voice control will be disabled.
