Terms & Conditions

1. The agreement

By creating a Logikoo account, or by using the app or this website, you accept these Terms & Conditions. If you do not accept them, do not use Logikoo. Our Privacy Policy forms part of this agreement.

"Logikoo", "we" and "us" mean DevHaven Apps, the developer and operator of the app. "You" means the person using it.

2. Who can play

You must be at least 13 years old to use Logikoo. Where the law of your country sets a higher minimum age for agreeing to online services on your own, that age applies instead, and below it you may only play with the consent of a parent or guardian who accepts these terms for you.

3. Your account

• Give a valid email address and keep it current — it is how we reset your password and reach you about your account.
• Keep your password to yourself. You are responsible for what happens under your account, unless it is our fault.
• One person, one account. Do not share, sell, buy or transfer accounts.
• Tell us promptly at support@devhavenapps.com if you think someone else has access to your account.
• You may delete your account at any time from inside the app. Deletion is described in section 10 of the Privacy Policy.

4. Your licence to use Logikoo

We grant you a personal, non-exclusive, non-transferable, revocable licence to install and use Logikoo on devices you control, for your own entertainment. That licence does not let you copy, sell, rent, sub-licence, modify, decompile or reverse engineer the app, except to the extent the law says you may regardless of what we write here.

5. Fair play

Leaderboards are the point of the competitive half of Logikoo, and they only mean anything if the results on them are genuine. You agree not to:

• use bots, scripts, macros, emulated input or any automation to play or to submit results;
• modify the app, tamper with its network traffic, or submit results other than through normal play;
• exploit a bug, glitch or unintended behaviour instead of reporting it;
• use multiple accounts to gain an advantage, or coordinate with others to manipulate rankings;
• interfere with our servers, or attempt to gain access to systems or accounts that are not yours.

We validate submitted results server-side. Results that are impossible for the game and difficulty they claim may be rejected or removed without notice, and accounts responsible for them may be restricted, reset or closed under section 13.

If you find a bug that could be exploited, tell us at support@devhavenapps.com. We would much rather fix it.

6. Virtual items and coins

All virtual items and currency exist only inside the game. They:

• have no monetary value and cannot be exchanged for money or anything of value outside the game;
• are licensed to you for use in the game, not owned by you;
• cannot be sold, traded or transferred to another person or account;
• may be changed, rebalanced, expired or removed as the game is tuned — drop rates, prices, energy costs and rewards are all subject to change;
• are lost when your account is closed or deleted, and are not refundable or restorable afterwards.

7. Leaderboards and seasons

Records are kept per game and per difficulty, and boards run in seasons that are settled when they end. By playing, you agree that your username, avatar, frame, banner, level and results may be shown publicly inside the app.

We may correct, recalculate, reset or remove entries — including at the end of a season, after a bug that affected scoring, or where the results were not honestly earned. Rewards paid out for a season are final unless they were obtained in breach of section 5.

8. Acceptable use

You agree not to use Logikoo to:

• choose a username that is obscene, hateful, harassing, impersonates someone else, or infringes a trademark;
• harass, threaten or abuse other players or our team;
• break the law, or encourage anyone else to;
• advertise, spam or promote anything.

We may change a username that breaks this section, with or without notice.

9. What you submit

You keep whatever rights you have in the content you submit — your username, feedback, support messages and bug reports. By submitting it you give us a worldwide, royalty-free licence to use it as needed to run the service, which for a username means displaying it to other players.

If you send us an idea or a suggestion, we may act on it without owing you anything for it.

10. Our intellectual property

Logikoo — its name, logo, artwork, sprites, sounds, interface, design system and code — belongs to DevHaven Apps and is protected by copyright and trade mark law. Nothing in these terms transfers any of it to you.

The underlying puzzles are public-domain classics; our implementations, boards and artwork are not. The Figtree typeface is used under the SIL Open Font License 1.1 and remains the property of its authors.

11. Stores and third parties

Logikoo is distributed through Google Play and the Apple App Store, and your use of those stores is governed by their own terms. Sign in with Google and Sign in with Apple are optional and governed by Google's and Apple's terms and privacy policies.

Apple and Google are not parties to this agreement and are not responsible for Logikoo, but where required by their rules they are third-party beneficiaries of it and may enforce it against you.

12. Availability and changes

We work to keep Logikoo running, but we do not promise it will be available uninterrupted or error-free. We may take it down for maintenance, change or remove features, add or retire games, and adjust the balance of the energy, task, chest and reward systems.

If we ever discontinue Logikoo entirely, we will give reasonable notice in the app where we can. Virtual items do not survive that, and are not compensated.

13. Suspension and termination

You may stop using Logikoo and delete your account at any time. We may suspend or terminate your account, remove your leaderboard entries or reset your progress if you materially break these terms — in particular sections 5 and 8 — or where we must do so by law. Where it is reasonable to do so, we will warn you first and explain why.

Sections 6, 9, 10, 14, 15 and 16 survive the end of this agreement.

14. Disclaimer

Logikoo is provided "as is" and "as available". To the fullest extent the law allows, we disclaim all implied warranties, including merchantability, fitness for a particular purpose and non-infringement, and we do not warrant that the app will be uninterrupted, secure or free of errors, or that any defect will be corrected.

Nothing here removes rights you have as a consumer under the mandatory law of your country.

15. Limitation of liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential loss, for lost progress, virtual items or leaderboard positions, or for any loss of data resulting from your use of Logikoo.

Because Logikoo is free and has no in-app purchases, our total liability to you for any claim connected with the app is limited to the amount you have paid us for it, which is zero, or to EUR 50, whichever is greater.

We do not exclude liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot lawfully be excluded.

16. Governing law

These terms are governed by the laws of the Republic of Serbia, and the courts of Serbia have jurisdiction over any dispute arising from them. 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 own country, and you may also bring proceedings there.

17. Changes to these terms

We may update these terms as the app changes. The date at the top of the page always shows the current version, and for material changes we will notify you in the app before they take effect. If you keep using Logikoo afterwards, the updated terms apply; if you do not accept them, delete your account.
