Last updated: 26 October 2026
Wallkeep is a free, offline castle defense game supported by advertising. The game itself does not collect, store or send any personal data. Your progress (waves, castle, archers, heroes, colonies, dragons, treasures, records, settings) is saved only on your device. The only third party that processes data is Google AdMob, which shows the ads.
The game keeps a small local save file with your progress and your settings (music, sound, language). This file never leaves your device and uninstalling the app deletes it. The game can also show your progress as a "save code" (a line of text) that you can copy yourself to move your progress to another phone: the game never sends this code anywhere.
The game shows a banner ad on the title screen and on the castle screen between waves, and occasional full-screen ads after the result of a wave. Ads are never shown during a battle. Rewarded videos are shown only when you choose to watch one (for example "Double gold: watch a video ad"). Ads are served by Google AdMob, a service of Google LLC. To deliver and measure ads, AdMob may collect and process:
This data is processed by Google according to Google's Privacy Policy and How Google uses information from sites or apps that use its services. You can reset or delete your advertising ID and opt out of ad personalisation in your Android settings (Settings > Google > Ads).
If you are in the European Economic Area, the United Kingdom or Switzerland, the game asks for your consent before showing personalised ads, using Google's User Messaging Platform (UMP). You can refuse, and you can change your choice at any time from Settings > Privacy choices inside the game. If you refuse, you will still see ads, but they will not be personalised.
Wallkeep is intended for a general audience aged 13 and over and is not directed to children under 13. We do not knowingly collect personal information from children. If you believe a child has provided personal data through the ads, please contact us and we will help you address it.
The game does not ask for an account, does not read your contacts, photos, files or precise location, does not use analytics SDKs other than the ones included in AdMob, and does not contain in-app purchases.
Since we do not receive any personal data, we do not store any on servers. Data processed by Google AdMob is retained according to Google's policies.
Depending on where you live, you may have the right to access, correct or delete personal data, or to object to its processing. For data processed by Google, please use the controls described above and Google's privacy tools. For anything else, contact us.
If this policy changes, the new version will be published at this address with an updated date.
