What this app uses
| Service | Used | What it does here |
|---|---|---|
| Google AdMob | Yes | A full-screen ad after a won stage, not after every one and never after a loss, a banner above the play area, plus rewarded ads you choose to watch. |
| Google Play Billing | Yes | One-off purchases: remove_ads, the theme pack skin_night,
four station paints sold one at a time or together as a bundle, four advanced
stations, and lab_researcher, a second researcher in the lab. Nothing
else, and no subscriptions. |
| Play Games sign-in, leaderboards and achievements | Yes | Optional. An endless board, a daily board and a campaign stars board, and ten achievements. Declining the sign-in changes nothing else in the game. |
| Play Games cloud saves | Yes, once you switch it on | Off until you turn it on from the More page, which needs Play Games signed in. While it is on, a copy of the save is kept by Google in your Play Games saved games, under your Google account. Turning it off in the same place stops the copies. We never receive the save. |
| Analytics, crash reporting, ad networks other than AdMob | No | None are built into the app. |
Status as of 29 September 2026. Keelhold is in testing on Google Play and is not public yet. This page is updated when it ships and whenever what it uses changes.
What it stores on your device
One save, in the app's private storage, under the key
stationdefense.save.v1. It holds your weapons with their levels and potential,
your modules, the station upgrades earned from boss kills, your base facilities and
research with the times they finish, your credits, alloy and cores, which stages are
cleared and their stars, your three loadout presets, your best endless run, the daily
streak, which paints and themes you own, your settings and what you have bought, along
with any leaderboard score or
achievement waiting to go to Google. None of it is sent to us, and uninstalling the app
deletes it from the device. With cloud saves switched on, the copy Google holds is
deleted from the Google Play Games app. The same list, in the general form, is
in the policy.
The rest of it
Everything else, meaning what Google receives, the consent form for players in the EEA and the UK, purchases, Play Games, children's data, your rights and how to delete things, is in the one policy that covers this game.
