// about · §01
Companion is the Android-side counterpart to PhoneToolkit. At sale or activation, the customer installs the Companion APK; the app generates an EC P-256 keypair on-device (TEE-bound on Knox hardware), signs intake metadata (IMEI, Build.SERIAL, photos), and uploads it to KAKEL's server.
When the device is later reported stolen, the customer files a stolen report through the same app. KAKEL coordinates: remote lock, location ping, evidence-bundle PDF generation for police filing, GSMA Device Check blacklist submission, and (when applicable) AppleCare / carrier escalation.
The APK is offered as a white-label product: phone vendors install their own branded version with their own backend instance.
