Terms & Conditions

Effective Date: 20th Oct 2026

Last Updated: 20th Oct 2026

Welcome to CLUEBELL STUDIO (“we”, “our”, “us”). These Terms and Conditions (“Terms”) govern your access to and use of Block Stack (the “Game”), together with our Privacy Policy.

Two things worth knowing before you spend anything. Virtual currency and items have no real-world value, cannot be exchanged for money, and are licensed to you rather than owned by you. And your progress is stored only on your device — if you uninstall the Game or clear its data, purchased coins cannot be recovered, though one-off unlocks such as Remove Ads, Double Coins and the Starter Pack can be restored through your store account.

Please read these Terms carefully before using the Game.

Acceptance Of Terms

By downloading, installing or playing the Game, you agree to comply with and be bound by these Terms. If you do not agree with these Terms, do not use the Game.

Eligibility

The Game is not directed to children under 13, and you must be at least 13 years old to use it. If you are under 18, or under the age of majority where you live, you may use the Game only with the consent of a parent or guardian, who accepts these Terms on your behalf and is responsible for any purchases made.

Licence To Use The Game

We grant you a personal, limited, non-exclusive, non-transferable and revocable licence to install and play the Game on a device you own or control, for your own non-commercial entertainment. We reserve every right not expressly granted here.

Virtual Items And Virtual Currency

The Game contains virtual currency (coins) and virtual items such as skins, upgrades and unlocks. These are licensed to you for use within the Game only. You do not own them.

  • They have no monetary value and cannot be exchanged, sold, transferred or redeemed for money or anything of value outside the Game.
  • They are not transferable between players, devices or store accounts, and cannot be moved between our games.
  • We may change, suspend, rebalance or remove virtual items and their prices, and may adjust what they cost or grant, as part of ordinary game updates.
  • Your licence to use them ends when your licence to use the Game ends.
In-App Purchases

Purchases are optional and are processed by Google Play or the Apple App Store. We do not receive or handle your payment details. Prices are shown in your local currency before you confirm.

Consumable purchases (coin packs) are delivered to the Game immediately and are used up as you spend them. One-off purchases (Remove Ads, Double Coins and the Starter Pack) remain associated with your store account.

Refunds are handled by the store you purchased from, under its policy and under any rights you have in law that cannot be excluded. We cannot issue refunds for store purchases ourselves. If a purchase is charged but not delivered, contact us and we will help you resolve it with the store.

Your Progress Is Stored On Your Device

The Game has no accounts, no login and no cloud save. Everything — your progress, purchases and coins — is kept in a file on your device, and we hold no copy. This has consequences you should understand before purchasing:

  • If you uninstall the Game, clear its data, or change device, that file is gone and consumable purchases cannot be restored, by us or by anyone.
  • One-off unlocks are tied to your store account and can be restored using the “Restore Purchases” option in the Game’s shop.
  • If the save file becomes unreadable, the Game will start afresh and will tell you it has done so.

We are not able to recover lost progress, and we do not compensate for it.

Advertising

The Game is free to play and is funded by advertising. Some adverts appear between rounds or when you return to the Game; others are optional and reward you for choosing to watch them. You can remove most advertising by purchasing Remove Ads, which does not affect optional rewarded adverts you choose to watch.

Advertising is supplied by third parties and we do not control its content. Your dealings with advertisers are between you and them, and we are not liable for any loss caused by them.

Acceptable Use

You agree to use the Game only for lawful purposes and in accordance with these Terms. You must not:

  • Modify, reverse engineer, decompile or create derivative works from the Game, except to the extent the law expressly permits it.
  • Use cheats, automation, modified clients or any method of obtaining virtual items other than through ordinary play or purchase.
  • Tamper with the Game’s save file or attempt to interfere with its operation.
  • Violate any laws or regulations, or infringe anyone’s rights.

We may suspend or end your licence if you do.

Intellectual Property

The Game and everything in it — code, artwork, audio, characters and the Block Stack name — is the property of CLUEBELL STUDIO or its licensors and is protected by copyright and other laws. You may not copy, modify, distribute or create derivative works from it without our express permission. These Terms give you a licence to play, and nothing more.

Termination

You may end these Terms at any time by uninstalling the Game. We may suspend or end your licence if you breach these Terms, or if we discontinue the Game. On termination your right to use the Game and any virtual items ends, and the sections that by their nature should survive — including Intellectual Property, Disclaimers, Limitation of Liability and Indemnification — continue to apply.

Disclaimers And Limitation Of Liability

The Game is provided “as is” and “as available”. To the fullest extent permitted by law we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We do not warrant that the Game will be uninterrupted, error free, or compatible with every device.

In no event shall CLUEBELL STUDIO be liable for any indirect, incidental, special or consequential damages, or for loss of data, progress or virtual items, arising out of or in connection with your use of the Game.

Where liability cannot lawfully be excluded, our total liability to you is limited to the greater of the amount you paid us in the twelve months before the claim, or INR 1,000. Nothing in these Terms excludes any right you have under consumer law that cannot lawfully be excluded.

Indemnification

You agree to indemnify, defend and hold harmless CLUEBELL STUDIO, its affiliates, employees and agents from any claims, losses, liabilities, damages or expenses (including reasonable attorneys’ fees) arising from your use of the Game or any violation of these Terms.

Privacy

Your use of the Game is also governed by our Privacy Policy, which explains what information is collected and how it is used, and which forms part of these Terms.

Governing Law

These Terms shall be governed by and construed in accordance with the laws of India. Any disputes arising out of or in connection with these Terms will be resolved in the competent courts of Chennai, Tamil Nadu, India, without prejudice to any right you have to bring proceedings in the country where you live.

Amendments

We reserve the right to modify these Terms at any time. Any changes will be effective upon posting the revised Terms, and we will update the effective date at the top of this page. Where a change materially affects your rights we will say so in the Game. Your continued use of the Game after such changes constitutes your acceptance of the modified Terms.
