How Does Facebook Use My Data in the Facebook App? Complete 2026 Guide
Millions of people open the Facebook app every day without fully understanding the volume of information it gathers or how that information shapes their experience. Meta’s privacy policy, last substantially updated on July 23, 2026, makes clear that data collection powers personalization, advertising, product improvement, safety systems, and increasingly Meta AI features. This guide breaks down exactly what the Facebook app collects, how Meta uses that data, recent changes in 2025–2026, and the concrete steps you can take to limit what is shared.
What Information Does the Facebook App Collect?
Meta’s official Privacy Policy (effective July 23, 2026) organizes the data it collects into several categories. The amount and type of data depend on how you use the app, the permissions you grant on your device, and the settings you choose inside Facebook and the Accounts Center.
1. Information You Provide and Activity on Meta Products
This is the most obvious category. It includes:
- Account details you enter when you sign up or update your profile (name, email, phone number, date of birth, gender).
- Everything you post, comment, like, share, or react to.
- Photos, videos, Stories, Reels, and the metadata attached to them (time, location if available, device information).
- Messages you send and receive (content and metadata). Note that some messaging products offer end-to-end encryption; when encryption is active, Meta cannot read the content of those messages.
- Interactions with Meta AI, including prompts, responses, and any details you share in one-to-one chats that Meta AI is allowed to remember for personalization.
- Search history, Marketplace activity, Events RSVPs, Groups membership, Gaming behavior, and Dating preferences where applicable.
Even if you never post publicly, your clicks, dwell time, and navigation patterns inside the app are logged.
2. Device, App, and Browser Information
The Facebook app collects technical data from the phone or tablet it runs on:
- Device type, operating system version, hardware characteristics, and unique identifiers.
- App version and performance diagnostics (crashes, battery usage, network conditions).
- IP address and network connection information.
- Whether the app is in the foreground or background, and certain device signals such as mouse or touch movement patterns (used partly for bot detection).
- Location-related information. This can come from GPS if you grant the permission, from IP address, from Wi-Fi or cell tower data, or from location tags and photo metadata you upload.
On both iOS and Android the app typically requests access to camera, microphone, contacts, photos, and location. These permissions are not required for basic use of the feed, but many features (posting photos, video calls, voice search, contact suggestions) will not work without them. Granting “Always” location access or full photo library access significantly expands what Meta can observe.
3. Information from Partners and Off-Platform Activity
This is one of the most significant and least visible sources of data. Businesses and websites that use Meta’s business tools (Meta Pixel, Conversions API, App Events, Facebook Login, Audience Network) send information about your activity on their sites and apps back to Meta. Examples include:
- Pages you visit and products you view or add to a cart.
- Purchases and offline conversions (for example, in-store purchases matched via loyalty programs or hashed contact data).
- Apps you open or actions you take inside apps that integrate Meta SDKs.
In mid-2026 Meta consolidated controls around this data. The older “Your activity off Meta technologies” disconnect option is being phased out in many regions and replaced by a broader “Activity from other businesses” setting. Turning this off limits how Meta uses partner-shared data for personalization of ads, feeds, and AI responses, but it does not stop partners from sending the data in the first place.
4. Camera Roll and Cloud Processing Features
In 2025 and 2026 Meta tested and rolled out optional features that can analyze photos and videos stored on your device. When enabled, the Facebook app may upload media from your camera roll to Meta’s cloud so Meta AI can generate suggestions such as collages, recaps, restyled images, or “moments you might want to share.” Meta states that this processing is opt-in, that the media is used only to generate suggestions for you, and that it is not used for advertising or to train general AI models unless you later publish or share the content. Nevertheless, continuous or frequent scanning of a personal photo library is a substantial expansion of access compared with simply uploading selected images.
How Meta Uses the Data It Collects
According to the July 2026 Privacy Policy, Meta uses the information it holds for several stated purposes. Understanding these purposes helps explain why certain data points matter.
Personalizing Your Experience
The primary use of your activity data is to rank and recommend content in the Facebook Feed, Reels, Stories, Groups, and Marketplace. In 2026 Meta expanded the use of off-platform activity for this purpose. For example, if a partner reports that you recently purchased camping gear, Meta may surface more camping-related Reels or Groups even if you never searched for them inside Facebook. The same signals can influence Meta AI responses when you ask for recommendations.
Meta AI also builds a limited form of memory from details you share in one-to-one chats (subject to your settings). This memory is used to make future answers more relevant. You can delete individual memories or turn the feature off in many regions.
Advertising and Measurement
Meta’s core business remains advertising. Data is used to decide which ads to show you, to measure whether ads lead to conversions, and to help advertisers build and refine audiences. Meta repeatedly states that it does not sell your personal information. Instead it uses the data internally and provides advertisers with aggregated or hashed targeting and measurement tools. Advertisers can still upload their own customer lists (hashed) and use Custom Audiences or lookalike modeling.
As of late 2025 and into 2026, interactions with Meta AI can also inform ad personalization in regions where that use is permitted.
Safety, Security, and Integrity
Meta uses account, device, and behavioral signals to detect spam, scams, account takeovers, and other abuse. Location anomalies, unusual login patterns, and device identifiers all feed into these systems. This is one of the few categories where restricting data can sometimes reduce the effectiveness of protective features.
Product Improvement and AI Development
Public posts, comments, and certain interactions can be used to train and improve Meta’s AI systems, including generative models. Private messages that are end-to-end encrypted are generally excluded. Meta has also stated that camera-roll media processed for sharing suggestions is not used for general model training unless the user chooses to publish it. Policy language continues to evolve, so checking the current Privacy Policy and AI-related notices remains important.
Research and Social Good
De-identified or aggregated data may be used for research, including studies related to public health, disaster response, or economic trends. Meta says it takes steps to prevent re-identification in these cases.
Recent Changes That Affect Data Use (2025–2026)
- July 2026 Privacy Policy update — Added clearer language around agentic AI capabilities and how Meta personalizes AI experiences.
- Expansion of off-platform data for feed and AI personalization — Previously used mainly for ads; now also influences organic content and AI responses.
- Consolidation of off-Meta activity controls — Older “disconnect” setting being replaced by the “Activity from other businesses” control in many markets.
- Camera-roll cloud processing features — Opt-in tools that upload and analyze on-device media for AI-generated sharing suggestions.
- Meta AI memory and personalization — Ability for the assistant to remember certain user-shared details across sessions.
These changes increase the value Meta can extract from existing data streams without necessarily collecting brand-new categories of information.
How to See and Control What Facebook Knows About You
Meta provides several tools, though they are scattered across the app, Accounts Center, and device settings.
1. Download Your Information
Inside Facebook go to Settings & privacy → Settings → Your information → Download your information (or use the Accounts Center equivalent). You can choose categories, date range, and format. The resulting archive often reveals the scale of location history, search logs, ad interactions, and off-platform events linked to your account.
2. Review Off-Platform / Activity from Other Businesses
In Accounts Center → Your information and permissions, locate the setting that controls activity shared by businesses. Clear historical data and turn off future use for personalization where the option exists.
3. Ad Preferences
Accounts Center → Ad preferences lets you:
- See and hide specific ad topics.
- Limit the use of partner data for ad targeting.
- Control whether profile information and social actions appear with ads.
Note that turning off personalization does not eliminate ads; it only makes them less tailored.
4. Device-Level Permissions
On iOS: Settings → Privacy & Security → review Location, Photos, Camera, Microphone, Contacts, Tracking. Set Facebook (and Messenger) to the minimum needed.
On Android: Settings → Apps → Facebook → Permissions. Restrict location to “While using the app” or deny it entirely if you do not need location features. Limit photo access to selected media only.
5. Camera Roll and Meta AI Settings
Inside the Facebook app, look for settings related to “Camera roll suggestions,” “Custom sharing suggestions,” or cloud processing. Turn these off if you do not want ongoing analysis of your photo library. For Meta AI memory, review and delete stored details or disable the feature where available.
6. Privacy Checkup and Apps & Websites
Run the Privacy Checkup tool. Under Apps and Websites, remove any third-party services you no longer use. These connections can continue to exchange data even after you stop actively using them.
7. Browser and App Alternatives
Using Facebook in a privacy-focused browser (with tracking protection enabled) or the official mobile web version reduces some of the deep device-level access the native app has. Some features are deliberately limited on the web, which is one reason Meta encourages the native app.
Does Facebook Sell My Data?
Meta’s Privacy Policy states: “We don’t sell any of your information to anyone, and we never will.” This statement is carefully worded. Meta does not transfer ownership of individual user profiles to third parties in exchange for money. It does, however, use the data to power a highly targeted advertising system and provides advertisers with tools that leverage that data. From a practical standpoint, the economic value of the data is realized through advertising rather than through outright sale of raw profiles.
Practical Privacy Checklist for 2026
- Run Privacy Checkup and limit who can see posts, profile details, and friend lists.
- Turn off or limit “Activity from other businesses.”
- Review and restrict Ad Preferences.
- Set device location permission to “While using” or “Never.”
- Limit photo library access to selected items only.
- Disable camera-roll suggestion / cloud processing features.
- Clear Meta AI memories and review AI settings.
- Remove unused apps and websites that have Facebook Login access.
- Download your information periodically so you know what is stored.
- Consider using the web version or a secondary account for lower-sensitivity browsing.
Final Thoughts
The Facebook app is designed as a data-rich product. Almost every interaction—scrolling, tapping, uploading, searching, or even keeping the app installed with certain permissions—generates signals that Meta uses to personalize content, target ads, improve AI systems, and protect the platform. The July 2026 Privacy Policy and the product changes that preceded it make the scope of that data use more explicit than in earlier years.
You cannot eliminate data collection entirely while continuing to use the service, but you can meaningfully reduce the most invasive streams. The combination of in-app controls, Accounts Center settings, and strict device permissions remains the most effective approach available to ordinary users in 2026. Review these settings at least a few times a year, because Meta continues to adjust both the features and the corresponding privacy options.
For the most authoritative and up-to-date details, always consult Meta’s own Privacy Policy and Privacy Center, as practices and regional options can change.
