Spring Kingdom Defense: TD
Privacy Policy
Effective November 13, 2026
Spring Kingdom Defense (formerly Dusk Bastion: Tower Defense; Android, package com.kausarstudio.springkingdomdefense)
Developer: Kausar Studio · Contact: support@kausarstudio.com
In short: the game has no accounts, and we (Kausar Studio) do not collect, receive or sell any of your personal data. Your game progress stays on your device. To show ads, the game uses Google AdMob, which collects some device and usage data as described below. Where the law requires it, you are asked for consent first, and you can change your choice at any time from the game's Settings or Pause screen.
Who we are
Spring Kingdom Defense is made by Kausar Studio, an independent developer. For any question about this policy, write to support@kausarstudio.com.
Information the game stores on your device
The game itself collects no personal data. It saves the following only on your device, so you can continue where you left off:
- Game progress: unlocked stages, best waves, stars earned, Royal Seals and Royal Workshop upgrades, and the battle in progress between waves.
- Settings: the Sound on/off choice and whether the tutorial and tips have been shown.
- Ad pacing: how many breaks and taps have passed since the last full-screen ad, when the last full-screen ad closed, how many full-screen ads were shown in this session, how many times each optional reward was used today, whether the Gold Chest of the battle in progress was opened, and which wave its War Horn was sounded for. These are used only to space ads out and to keep each reward within its limits.
- Rating prompt: when you first opened the game, how many sessions and victories you have had, and when (and how many times) Google Play's rating card was shown, so it is shown rarely (see "Ratings" below).
This information never leaves your device through the game and is not sent to us. If Android's backup feature is turned on for your Google account, Android may include this small save file in your device backup, handled by Google under its own privacy policy. Uninstalling the game, or clearing its storage in Android Settings, deletes this data.
Advertising (Google AdMob)
The game shows these ads provided by Google AdMob (Google LLC). No ad appears during a battle, and Stage 1 (the tutorial) shows no ads:
- A full-screen ad between battles, from Stage 2 on: when you leave a victory or defeat screen (Continue, Retry wave, Restart stage, Map or Back), a short "Ad break" notice counts down for 3 seconds and one full-screen ad may play. It comes at most once every two of your taps that start a battle or a wave or leave a result screen, and never within 1 minute of another full-screen ad.
- Optional rewarded ads, from Stage 2 on, each at most 5 times a day: Bonus Gold (extra gold before the first wave), the Gold Chest (extra gold between waves, once per battle), Revive (your castle stands again with half its lives, once per attempt), the War Horn (+30% tower damage during one boss wave: waves 5, 10, 15 and 20, once each), Retry with gold (retry the wave with extra gold) and ×2 Seals (the Royal Seals of a victory once more, once per victory). The reward is named before the ad plays, and you never have to watch one.
- An ad card marked "Ad" (a "native" ad) below the buttons on the victory and defeat screens, from Stage 2 on.
To serve and measure ads, Google's Mobile Ads SDK automatically collects and shares with Google the following data:
| Data | What it is | Why |
|---|---|---|
| Approximate location | Your device's IP address, which can be used to estimate a general location | Advertising, analytics, fraud prevention |
| Device or other identifiers | Android advertising ID, app set ID and, where applicable, identifiers related to accounts signed in on the device | Advertising, analytics, fraud prevention |
| App interactions | Interactions such as app launches, taps and ad views | Advertising, analytics, fraud prevention |
| Diagnostics | Performance information such as app launch time, hang rate and energy usage | Analytics, fraud prevention |
This data is encrypted in transit (TLS) and is processed by Google, not by us. Ads are limited to content suitable for general audiences with parental guidance (rating PG). Learn how Google uses this information: https://policies.google.com/technologies/partner-sites and the Google Privacy Policy: https://policies.google.com/privacy.
Permissions
| Permission | Why |
|---|---|
| Internet | to load ads and to open this policy and the terms |
| Network state | to load ads and open links only when the device is online |
| Advertising ID (com.google.android.gms.permission.AD_ID) | used by the Google Mobile Ads SDK for advertising, analytics and fraud prevention |
| Android ad services (ACCESS_ADSERVICES_AD_ID, _ATTRIBUTION, _TOPICS) | added by the Google Mobile Ads SDK for Android's Privacy Sandbox advertising APIs, where available |
| Wake lock and foreground service | added by Google's libraries to finish short background tasks of the ads SDK |
These come with the Google Mobile Ads SDK. The game asks for no other permission: no location, contacts, camera, microphone or storage access.
Ratings (Google Play In-App Review)
Now and then, after a victory, the game may show Google Play's own rating card (at most once every 90 days and 3 times in total, never in your first days of play). The card, your star rating and any review you write are handled by Google Play under Google's terms and privacy policy; the game never sees whether or how you rated it and stores only when the card was shown. You can also rate the game any time from Settings › Rate this app, which opens its Google Play page. Nothing is given or taken away for rating.
Your consent (EEA, United Kingdom and Switzerland)
If you are in a region where consent is required, a consent message from Google's User Messaging Platform appears when you first open the game, before any ad is requested. You can accept, decline or manage your choices. You can change your decision at any time: open the game and tap Privacy options, in Settings (the gear on the journey map) or on the Pause screen during a battle. Your consent choice is stored on your device.
Your choices
- Read this policy and the terms: Settings > Privacy policy or Terms of service, or Pause > Privacy policy. They open on our website; without an internet connection the game shows the address to copy.
- Advertising ID: you can reset or delete your advertising ID in Android Settings (Privacy > Ads, or Google > Ads, depending on your device).
- Personalized ads: where consent applies, use Privacy options in the game. You can also manage ad settings at My Ad Center: https://myadcenter.google.com.
- Play offline: the game is fully playable without an internet connection; no ads are loaded while you are offline.
- Delete your data: uninstall the game or clear its storage to remove all data kept on your device. For data held by Google, use Google's tools linked above.
Children
Spring Kingdom Defense is intended for players 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 information through the game, contact us and we will help remove it.
Data retention, deletion, sharing and security
We do not keep, sell or share any personal data, because the game does not send personal data to us. The data on your device stays until you uninstall the game or clear its storage. Data collected by Google AdMob is kept, deleted, protected and, where needed, transferred to Google's servers in other countries under Google's policies. The game itself does not use analytics, has no accounts and does not offer in-app purchases.
Your rights
Depending on where you live (for example under the GDPR, the UK GDPR, Indonesia's Personal Data Protection Law (UU PDP), or US state privacy laws such as the CCPA/CPRA), you may have rights to access, correct, delete or object to the processing of your personal data, and to opt out of personalized advertising. Because we do not hold your personal data, these requests are handled through the choices above and through Google for ad data. You are welcome to contact us with any question.
Changes to this policy
We may update this policy, for example when the game adds new features. The effective date at the top shows the latest version. Significant changes will also be mentioned in the game's update notes.
