Trace — see what your phone tells every app

What is Trace

Every app you install learns a little about you.

Not your name. Small details your phone hands over without asking, which add up to a fingerprint that can follow you from app to app. Trace reads them the way any app could, live on your phone, and shows you what each one is and why it matters.

Three layers

1. Without asking: identifiers, device, settings, sensors, network, installed apps and clipboard
2. After one prompt: location, movement, nearby devices, contacts and calendar
3. After a switch in Settings: every notification, and how you use your phone, down to when you sleep

What stands out

• Every value is marked high, medium or low for how much it narrows your phone down
• One list gathers everything rare enough to single you out
• Each value shows the exact Android API an app calls to read it
• Export a full report, or copy any single value

Private by design

Trace has no account, ads or analytics, and keeps nothing it reads. Only two lookups leave the phone, both to find a place. Read the privacy policy.
