Terms of Service
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: you may play Spring Kingdom Defense for personal, non-commercial use. The game is free and shows ads from Google AdMob. Your progress is saved only on your device. Please don't tamper with the game or its ads. The game is provided as is, and these terms are governed by the laws of the Republic of Indonesia.
Who we are
Spring Kingdom Defense, formerly Dusk Bastion: Tower Defense ("the game"), is made by Kausar Studio, an independent developer ("we", "us"). By installing or playing the game you agree to these terms. If you do not agree, please do not use the game.
License to play
We grant you a personal, non-exclusive, non-transferable and revocable license to install and play the game on devices you own or control, for your own non-commercial entertainment. The game, including its artwork, music, sound effects, text and code, remains the property of Kausar Studio and its licensors. These terms do not give you any other rights to it.
Ads
The game is free to play and is supported by ads provided by Google AdMob. No ad appears during a battle, and Stage 1 (the tutorial) shows no ads. From Stage 2 on, when you leave a victory or defeat screen, a short "Ad break" notice counts down for 3 seconds and one full-screen ad may appear, 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; it can be closed as allowed by the ad. The victory and defeat screens may also show an ad card marked "Ad", and from Stage 2 on the game may offer optional rewarded ads (Bonus Gold, the Gold Chest, the War Horn, Revive, Retry with gold and ×2 Seals). Watching optional ads is always your choice, and declining never removes anything you earned. How ads use data is explained in the Privacy Policy. Ads are shown by Google, and we are not responsible for the content of third-party ads or for the products and websites they link to.
Ad rewards
- A reward is given only after the whole ad was watched and Google AdMob confirms it. If the ad is closed early, does not load or is not confirmed, no reward is given, and the progress you already made is never affected.
- Each reward can be earned at most 5 times a day. Bonus Gold can be used once per battle start, before the first wave; the Gold Chest once per battle, also after leaving and continuing that battle; Revive once per attempt; Retry with gold when Revive is not offered on a defeat; ×2 Seals once per victory, on top of the Royal Seals the victory already gave; the War Horn once per boss wave (waves 5, 10, 15 and 20), for that wave only, also after leaving and continuing that battle.
- Ads are not always available (for example without an internet connection, within 1 minute of another full-screen ad, or when Google has no ad to show), so a reward offer may not appear every time.
- Rewards are virtual items for use only in the game, with no real-world value. They cannot be exchanged, transferred or refunded.
- Every battle can be won without watching ads; after repeated defeats on a wave the game also sends free reinforcements.
Ratings
After a victory the game may now and then show Google Play's own rating card, and Settings › Rate this app opens the game's Google Play page. Rating is always optional: nothing is given for it and nothing is taken away if you don't.
No purchases
The game does not offer in-app purchases or paid content.
Your progress
Your progress and settings are saved only on your device. We cannot see, restore or transfer them. Uninstalling the game, clearing its storage, or losing or resetting your device may delete your progress permanently, and we cannot guarantee that it can be recovered.
What you must not do
When using the game, you must not:
- copy, modify, decompile, reverse engineer or create derivative works of the game, except where the law expressly allows it;
- remove or alter any copyright notices or branding in the game;
- interfere with, fake or automate ad views or clicks, or otherwise try to defraud the ad network;
- distribute, sell, rent or sublicense the game, or offer it through unofficial sources;
- use the game in any way that breaks the law.
We may end your license if you break these terms.
Disclaimer
The game is provided "as is" and "as available". To the fullest extent allowed by law, we make no promises that the game will be error-free, uninterrupted or compatible with every device, and we disclaim all warranties, express or implied.
Limitation of liability
To the fullest extent allowed by law, Kausar Studio is not liable for any indirect, incidental or consequential damages, or for any loss of data or game progress, arising from your use of the game. Nothing in these terms limits any rights you have under consumer protection laws that cannot be excluded.
Termination
You may stop using the game at any time by uninstalling it. Your license ends automatically if you break these terms.
Governing law
These terms are governed by the laws of the Republic of Indonesia.
Changes to these terms
We may update these terms, for example when the game adds new features. The effective date at the top shows the latest version. If you keep playing after a change, the updated terms apply.
