How to do it
Android does not provide a standard menu toggle for captive portal checks; you must use an ADB shell command to disable captive_portal_mode.
Menu names may differ by device and version.
What you lose
Public Wi-Fi networks requiring a browser sign-in may not prompt automatically or connect properly.
What is collected
Ip address, request timestamps, http response headers.
The checks exist to detect restricted local networks and launch captive-portal login pages when required.
Retention is not stated here. The sensitivity rating is this site's own estimate.
