What it does
The app's own description, verbatim:
Share your approximate (city-level) location to strengthen network verification.
That is the whole feature. Location at city resolution, attached to network measurements.
What it collects — and what it does not
Collected: approximate location, at city resolution, attached to network measurements.
Not collected: precise location. The app's permission text states that your precise location never leaves the device.
In plain terms, a city-level tag can associate a measurement with an area, while a precise coordinate is what identifies a person. The task is designed around the first.
The permission it asks for — Android
On Android, Extended Telemetry needs location set to "Allow all the time." The app's prompt text, verbatim:
Requires location set to 'Allow all the time' so it can keep running while the app is closed; turn it off anytime. Your precise location never leaves the device.
"While the app is closed" is the part that matters. A measurement taken only while the app is open would cover the moments you happen to be looking at your phone — the least useful sample of your day.
On iPhone
iOS uses a different label for the same setting: "Always." The wording quoted above was captured on Android. The equivalent iPhone prompt is not reproduced here because it has not been checked.
Does my device qualify?
Extended Telemetry requires at least software attestation. Unetwork's guide states it directly:
Extended Telemetry and Entropy currently require at least software attestation.
For this task, the two attested states are equivalent:
For Extended Telemetry, hardware and software attestation are currently treated the same.
An unattested device can still connect:
An unattested device cannot currently participate in Extended Telemetry or Entropy, so its incentive opportunities can be more limited, even though it can still connect to the network.
You do not need to do anything to attest a device. The app does it on its own.
Runs on which phones
iPhone and Android.
Turning it off
A ULO can turn each task on or off in the app.
Switching Extended Telemetry off stops that task. Your license keeps running and your other tasks are unaffected.
The location permission itself is separate from the task toggle. If you revoke it in your phone's settings, under the Unetwork app's location access, the task cannot run without it.
Why this page exists
Most of what the app does is documented somewhere. Extended Telemetry is not — the permission prompt is the only explanation most operators get, and a prompt asking for always-on access with no context is the kind of thing people decline on instinct.
The request is narrower than it looks. City-level, not precise. And it can be switched off.
