Terms of use

Effective November 9, 2026

Dino Battle is operated by Quasi Convex Union, California, USA. These terms govern your use of the game. Questions? Email ask@convex.io.

Playing and accounts

You may play Dino Battle for personal, noncommercial use. Adults must purchase and manage subscriptions. If a child uses an account, their parent or legal guardian must manage it and agree to these terms on their behalf.

Keep access to your account email secure. Signing in uses an email code or link. Paying with an existing account's email does not give you access to that account without signing in.

Do not interfere with the service, access another person's account without permission, or use the game unlawfully. We may restrict access when reasonably necessary to address abuse, fraud, or security risks.

Premium subscriptions

Checkout shows the price, currency, and billing interval before you pay. Premium is a recurring monthly subscription. You authorize recurring charges at the disclosed rate until you cancel. Our payment provider processes payments. Any applicable taxes or additional charges will be disclosed before payment.

To cancel, sign in, open your account, choose Manage subscription, and confirm cancellation. Cancellation stops future renewals; access continues through the already-paid period. You can also contact ask@convex.io for help. Signing out or clearing your browser does not cancel a subscription.

Payments are generally nonrefundable, including unused portions of a billing period. We may grant refunds case by case; contact us to request one. This does not limit refunds or other remedies required by law.

Any subscription price change will be communicated before it takes effect, with notice and consent where required by law. You can cancel before the changed price applies.

Your adventures

Guest adventures are saved in your browser. Clearing browser data, using another browser, or losing the device can make them unavailable. Premium adds account saves across devices.

Claiming a guest adventure moves it to the signed-in account after confirmation. It is then available through that account rather than guest play. Signing out does not delete it.

When Premium ends, paid areas and cloud uploads stop. Existing account saves remain available, and syncing resumes when Premium returns. Cancellation does not request deletion of your account or saves. See our Privacy policy.

Service and your rights

The game and its features may evolve. We aim to keep it available and preserve progress, but cannot promise uninterrupted operation or that saves will never be lost. To the extent permitted by law, the service is provided as available without additional warranties. Nothing in these terms excludes liability or consumer rights that cannot legally be excluded.

California law governs these terms, subject to any mandatory protections that apply where you live. If we materially change these terms, we will provide notice in the game or by email before the changes take effect and update the effective date.
