These terms apply to the three NIOL apps — Sudoku Lab, Block Lab and Decifra. By installing and using any of them, you agree to what is set out here.
Using the app
The apps are free, with ads (through Google AdMob), some of them optional, that help fund development. Sudoku Lab has a "Remove Ads" option reserved for future versions — as of today, none of the three apps sells anything inside the app.
Decifra coins are virtual: they only exist inside the game, have no cash value and cannot be bought, sold or transferred.
Ownership
Code, design, icons, sounds and all app content belong to NIOL. You may use the apps freely for personal use; you may not redistribute, resell, reverse-engineer or modify them.
No warranties
The apps are provided "as is". We test thoroughly before every release, but we do not guarantee they will be 100% free of bugs at all times.
Limitation of liability
To the extent permitted by law, NIOL is not liable for indirect damages arising from use of the apps.
Changes
We may update the apps and these terms at any time. Continuing to use the app after a version update means you accept the new terms.
Governing law
These terms are governed by the laws of Brazil.
