Applies to the mobile game Boomstack
(io.nestengineering.boomstack) on Android and iOS.
Last updated 29 August 2026.
By downloading or playing Boomstack you agree to these terms. If you do not agree to them, do not use the game.
Boomstack is provided by Nest Engineering (“we”, “us”). Contact: support@nestengineering.io.
We grant you a personal, non-exclusive, non-transferable, revocable licence to install and play Boomstack on devices you own or control, for your own non-commercial entertainment. You may not sell, rent, sublicense or redistribute the game, and you may not reverse engineer, decompile or modify it except to the extent that applicable law expressly permits despite this restriction.
You must be at least 13 years old, or the minimum age of digital consent in your country if that is higher, to play. If you are a minor, you confirm your parent or guardian has read and accepted these terms on your behalf.
You agree not to cheat, use unauthorised third-party software, tamper with the game’s save data or network traffic to gain an advantage or obtain paid content without paying, or otherwise interfere with the game’s operation for anyone. We may suspend access or reset progress where we detect this.
The free version of the game shows advertising, including full-screen ads between some levels and optional ads you may choose to watch for a reward. Advertising is served by Google AdMob; what that involves for your data is set out in the Privacy Policy. We do not control the content of individual ads. Removing ads through an in-app purchase stops the forced ads; optional reward ads remain available if you choose to watch one.
Your progress is stored on your device only. There is no cloud save and no account. If you delete the game, change device, or clear its data, your progress is gone and we cannot restore it — we never had a copy. Non-consumable purchases can still be restored through your store account.
We may update, change or discontinue the game or any part of it, and we do not promise it will always be available or error-free. We may end support for older operating system versions or devices.
The game, its code, art, models, music, sound and name are owned by us or licensed to us and are protected by copyright and trade mark law. Nothing in these terms transfers any of that to you. Third-party components are used under their own licences, and the notices those licences require ship with the app.
To the fullest extent permitted by law, the game is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. Some jurisdictions do not allow the exclusion of implied warranties, in which case this clause applies to you only so far as the law permits.
To the fullest extent permitted by law, we are not liable for indirect, incidental, special or consequential damages, or for lost data or lost progress. Our total liability to you for any claim relating to the game is limited to the greater of the amount you paid us for in-app purchases in the twelve months before the claim, or USD 50. Nothing here limits liability that cannot be limited by law, including for death or personal injury caused by negligence, or for fraud.
If you are a consumer, you have statutory rights that these terms do not affect. Nothing here removes a right you have under the mandatory law of your country of residence.
You may stop using the game at any time by uninstalling it. We may suspend or end your licence if you materially breach these terms, in particular section 4.
We may update these terms. The date at the top of this page shows the current version. Material changes will be announced in the game before they take effect. Continuing to play after that means you accept the new terms.
These terms are governed by the laws of Ukraine, without regard to its conflict of law rules, and the courts of Ukraine have jurisdiction over any dispute. If you are a consumer resident in the EEA or the UK, this does not deprive you of the protection of the mandatory law of your country of residence, and you may bring proceedings there.
These terms are between you and us, not with Apple or Google. Apple and Google are not responsible for the game or its support, and have no obligation to provide maintenance or to address any claim relating to it. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
