How social networks track you
Meta, TikTok, Snap, LinkedIn, and others collect rich signals inside their apps and extend reach to partner websites through pixels — building profiles from what you watch, like, share, and click off-platform.
On-platform signals
Every like, follow, comment, dwell time, and reel completion trains ranking and ad models. Logged-in identity ties this behavior to your account across phone and desktop web.
Off-Facebook Activity (and similar settings on other platforms) shows partner businesses that shared event data with the network — often via pixels on their sites.
Pixels and partner data
The Meta Pixel, TikTok Pixel, and counterparts fire on publisher sites when you browse while cookies or storage allow matching. Login buttons ("Sign in with Facebook/Google") can share account linkage with embedded widgets.
Social platforms also buy or match data broker segments for ads — see our audiences guide.
High-impact social signals
- Engagement graph — likes, shares, watch time, DMs metadata
- Partner pixels — ecommerce events on non-social sites
- Device graph — same login on app and mobile web
- Location check-ins — optional but powerful when enabled
Browser tool vs social apps
We analyze your browser when you visit our site — not your Instagram or TikTok app session. Fingerprint and cookie signals still matter for social login flows and embedded widgets in browsers.
- Run a browser analysis after adjusting privacy settings.
- Review off-platform / ad personalization settings inside each social app.

Does Meta listen through my phone for ads?
There is little public evidence of microphone-based ad targeting at scale. On-platform behavior and partner pixels explain most spooky ad timing.
If I delete the app, am I untracked?
Your account data may be retained per policy. Partner pixels on other sites can still fire in your browser unless you block them or log out everywhere.
Are "Sign in with Google" buttons tracking?
They can pass account identifiers to the site you visit and to the identity provider, linking sessions across services.
