These terms cover the Cube Solver website, iOS and Android apps, and related services operated by Optional Chaining Technologies Ltda. If you lack legal capacity to agree or make a purchase, a parent or guardian must act where required by law. See our Privacy Policy.
Using Cube Solver
Use Cube Solver for personal puzzle solving, practice, and learning. The tools are educational aids, and results can be incomplete or inaccurate. Check instructions against your puzzle and never force a turn. Keep private access links secure and save copies of records you want to retain.
Acceptable use
Do not access the services without authorisation, interfere with other users, bypass purchase or service limits, or disrupt the services. We may restrict access as reasonably necessary to prevent misuse, protect users or the services, or comply with law.
Purchases, trials and renewal
Check the offer for features, price, billing interval, and trial or introductory terms before purchase. One-time purchases do not renew. Subscriptions renew automatically until cancelled. A trial or introductory offer that converts to paid access will be charged at the stated price unless cancelled by the applicable deadline. Price changes are subject to store rules and applicable notice and consent requirements.
Cancellation and refunds
Manage or cancel subscriptions through Apple or Google Play. Deleting the app does not cancel a subscription. Cancelling renewal does not request a refund. See Apple refunds or Google Play refunds, or contact us for purchase support. Store procedures do not limit statutory withdrawal, refund, or other consumer remedies.
App store terms
Store terms govern store accounts and billing. Apple’s standard app licence applies unless an applicable custom licence replaces it. See the Google Play terms for Google Play downloads.
Content and trademarks
Software and materials are subject to their applicable rights and licences. These terms do not restrict rights granted by law or another applicable licence. Rubik’s is a trademark of Spin Master Toys UK Limited. Cube Solver is independent and is not affiliated with, sponsored by, or endorsed by that company.
Availability and consumer rights
Features may change, be interrupted, or be discontinued, subject to applicable law and your rights under existing purchases. We may update these terms, subject to any required notice, agreement, or remedy.
Where permitted by law, we make no additional guarantees of availability, compatibility, or accuracy, and are not liable for losses that were not reasonably foreseeable when the agreement was made. These terms do not limit liability for fraud, intentional misconduct, gross negligence, or death or personal injury caused by negligence. They preserve all guarantees, rights, remedies, and liabilities that cannot lawfully be excluded or limited. You may bring a claim in any court with jurisdiction under applicable law.
