Legal
Terms of Use
Last updated September 29, 2026
These terms apply to the Contrapunctus game and its online services, made by Jeharli. By playing you agree to them. The App Store or Google Play terms also apply to your download and purchases.
Your player
The game creates a guest player on your device. You may create an account to publish levels and use the social features. Keep your sign-in details private; you are responsible for what happens under your account.
Anyone may play. Creating an account and publishing levels require you to be old enough to agree to these terms where you live (13 in the United States, up to 16 in parts of the EU), or to have a parent's or guardian's permission.
Virtual currency and items
Notes and Sharps are in-game currencies. They and the items they buy have no cash value, cannot be exchanged for money or transferred between players, and are licensed to you for use in the game. Real-money purchases are either consumable (currency packs) or one-time purchases you keep (Ad-free, Creator Pro, Level Maker Pro, themes). Every level and every sound library is free, and nothing that affects scoring is sold. Refunds are handled by the store you bought from.
If you live in the EU or UK, you agree that digital content you buy is delivered immediately, and you acknowledge that you lose the right of withdrawal once delivery has begun. This does not affect your other legal rights.
Classroom Unlimited (subscription)
Classroom Unlimited is the game's only subscription. It is for teachers and lets you run as many classes as you need, without ads. It is billed monthly or yearly through the App Store or Google Play and renews automatically at the price shown in the store, unless you cancel at least 24 hours before the end of the current period. Manage or cancel it in your App Store or Google Play account settings. Cancelling stops the next renewal, and you keep Classroom Unlimited until the period you paid for ends. Students never pay to join a class.
Classes
Teachers and assistants who run a class are responsible for using it appropriately with their students. Where you teach students below the age of digital consent, you must have the school's authority or a parent's consent, as the law where you teach requires (see Children and schools). Use student results only for teaching. Students can leave a class at any time.
Advertising
The free game may show ads between games and optional rewarded ads you choose to watch. Ad-free or Classroom Unlimited removes the ads between games.
Levels you create
You keep ownership of what you create. By publishing a level you give us a worldwide, non-exclusive, royalty-free licence to host, display, distribute and let other players play and save it, and — if you allow featuring when publishing — to include it, always credited to you, in campaigns and daily challenges.
Publish only music you have the right to share: works in the public domain (for example most music by composers who died more than 70 years ago, in editions you arranged or that are themselves free), or music you wrote. Do not publish copyrighted arrangements or recordings without permission.
Community rules
- No hateful, sexual, violent or harassing content in levels, names or profiles.
- No cheating, exploiting bugs, automating play or manipulating votes and play counts.
- No impersonating other players, composers' estates or Jeharli.
We may remove content and suspend or ban players who break these rules. Report problems from any level's page in the game.
Copyright complaints
If you believe a level infringes your rights, email [email protected] with the level's name or link, the work concerned, and your contact details. We will review it promptly and remove infringing content.
The service
We work to keep the game running but provide it "as is". Features, levels and prices may change. Online features need an internet connection; levels you saved offline keep working without one.
Liability
To the extent the law allows, we are not liable for indirect or consequential losses. Nothing in these terms limits rights you have as a consumer under the law of your country.
Ending
You can stop playing and delete your account at any time. We may end these terms if you seriously or repeatedly break them.
