Go to Profile → Settings → Data & Personalization to control how your data influences your experience.
Personalized Feed
When on, the feed can use your activity (posts you've liked, accounts you follow, content you interact with) to improve how posts are ranked for you. When off, the feed uses simple recency and popularity only — no activity tracking.
Location-Based Content
When on, posts near your location can be surfaced more readily. When off, no location data influences what you see.
Analytics
When on, we collect anonymized usage data to improve the app — things like which features are used most and how long screens are viewed. No personal content is included. When off, no analytics events are sent from your account.
Turning off all three is fully supported. The app works normally — your experience will simply be less personalized.
