Spinhold Privacy Policy
Last updated: October 11, 2026Spinhold: Castle Defense (“the app”) is a single-player castle defense game for Android, made by Vaxuum.games, the game studio of Vaxuum, LLC (“we”, “us”). This policy explains what information the app handles.
Information stored on your device
Your game progress (levels, stars, gold, gems, castle and weapon upgrades, daily chest) and your settings (music, sound and vibration) are saved only on your device so you can keep playing. This information never leaves your device and we cannot see it. You can erase it at any time by clearing the app’s storage or uninstalling the app.
Advertising (Google AdMob)
The app shows ads provided by Google AdMob: optional rewarded videos that you choose to watch (for example to revive, double your gold, re-roll an upgrade card or open the daily chest), and full-screen ads between some levels. When the app requests or shows an ad, the Google Mobile Ads SDK automatically collects and sends to Google: your IP address (which can indicate approximate location), your device’s advertising ID and other device identifiers, your interactions with ads, and diagnostic information. Google uses this data for advertising, analytics and fraud prevention. The data is encrypted in transit. See How Google uses information from sites or apps that use its services.
In the European Economic Area, the UK and Switzerland, the app asks for your consent through Google’s consent message before personalized ads are shown. Where this applies, you can change your choice at any time with Settings › Privacy choices. On any Android device you can reset or delete your advertising ID in your device’s settings.
Analytics (Google Firebase)
The app uses Google Firebase Analytics to understand how the game is played so we can balance and improve it: for example which levels are started, won or lost (and on which wave), boss fights, which upgrade cards are picked, upgrades bought, daily chests opened, whether ads are offered and watched, the highest level reached, and whether ads have been removed. Firebase also collects an app instance ID, device model and Android version, and approximate location from your IP address. We do not use this data for advertising, and it is not linked to your name or any account. See Privacy and Security in Firebase.
Purchases
The app is free to play. It may offer an optional one-time purchase to remove ads. Purchases are processed by Google Play under Google’s terms; we never receive your payment details. The app only remembers on your device that ads have been removed, so the purchase can be restored if you reinstall.
Information we collect
Apart from the advertising and analytics data described above, which goes to Google, the app does not collect, sell or share any personal information. There are no accounts, no sign-in and no chat.
Children
The app is not directed at children under 13 and we do not knowingly collect personal information from children. If you believe a child has provided personal information through the app, contact us and we will help remove it.
Changes
If a future version changes what information the app handles, we will update this policy before that version is released and change the date above.
