Decision sheet — What a tracker can do
How does a phone tracker work?
You want to know what a tracking app can actually reach on a phone.
Verdict
Permission-bound
A tracking app can use data the device and user allow it to access. Location, activity and message content are different permissions and must not be bundled into one promise.
How to check
- Identify the exact device and account being used.
- Read the app permission request and its data policy.
- Test only the feature the owner has enabled.
The honest limit
A web page cannot silently discover another phone’s location from a number alone.
