Privacy policy
This policy covers the game Grid Lockdown: Tower Defense on Android and on the web. Last updated 6 October 2026.
Who we are
Grid Lockdown is published by Nets Pens Games. Questions about this policy go to netspens@gmail.com.
What the game stores
There is no account. Crystals, your best wave, upgrades, and the theme choice stay on the device, in the app’s local storage or, in a browser, in that browser’s storage. The game does not upload that save.
Ads
The game is free. Optional rewarded ads can grant crystals, gold, or one more chance. You choose when to watch one. A short ad can also appear between waves after the game has been open for a bit. It does not appear in the first moments of a session.
Ads are served by Google AdMob. Google may use the Android advertising ID, and similar technical data in the browser, to show and measure ads. That is the advertising data the game collects. Grid Lockdown does not sell personal information.
Purchases
There is nothing to buy.
Children
Grid Lockdown is not directed at children under 13, and it is not part of a kids’ program.
Deleting your data
In the game, open Settings, then About, then Delete my data, and confirm. That removes the save on that device. You can also clear the app’s storage, uninstall it, or clear the site data in your browser. There is no cloud profile to delete.
