This hub stores your email, tester ID, alias and private feedback in Firebase for the test owner. If you choose activity sharing, the game also sends UTC day, active expedition seconds, kills, mined nodes, lantern waves, completed runs, build version and server receipt time, linked to your tester ID. The owner uses these summaries to understand test coverage and find issues. Reports can arrive late or be missing and cannot verify attention, enjoyment or Google Play eligibility.

Sharing is optional and is off unless you choose it. You can play without it and turn it off any time. Updated tester builds stop locally and discard unsent reports from the upload queue immediately; account-wide and other-device withdrawal needs a successful sync. A request already sent may still arrive, and earlier reports remain until deletion. Older installed builds require successful online withdrawal; update before relying on immediate offline withdrawal. An unreadable activity queue is preserved and cannot upload until safe recovery; if local withdrawal cannot be saved, the app stops collection for the session and asks you to retry. See the privacy notice.

Newer Android builds carrying the Google Play access check keep only a small access decision on the device; raw Store age signals are not sent to this hub. They require a shared 18+ range and your explicit choice before opening connected accounts. NOT_SHARED permits conservative ordinary offline play where allowed. The age-access QA build has ads disabled. This feature adds no automatic daily Store query or daily telemetry job; older installed builds do not acquire it from this notice.
