Terms of Service

These Terms of Service form a binding agreement between you and the sharp.go project ("we", "us", "sharp.go"). The project is not operated by a registered legal entity. By creating an account or using the sharp.go service, you accept these Terms.

sharp.go provides a 3D web-based Weiqi (Go) game with AI and online multiplayer modes. Some features may be free, some may require a paid subscription.

We may modify, suspend, or discontinue features with reasonable notice. We do not guarantee uninterrupted availability.

You are responsible for safeguarding your credentials and for all activity under your account. Notify us immediately of any unauthorized use.

You must provide accurate registration information and keep it up to date.

You agree to use sharp.go only for lawful purposes and in accordance with our Acceptable Use Policy. Cheating, automated play, harassment, and abuse of infrastructure are prohibited.

The sharp.go game client, engine, branding, and original content are owned by us or our licensors. You retain ownership of game data you generate (your games, replays, annotations) and may export it at any time in an open format.

Paid subscriptions renew automatically until cancelled. You may cancel at any time and continue using paid features until the end of the current billing period.

Except where required by law, fees are non-refundable.

To the maximum extent permitted by applicable law, sharp.go is provided "as is" without warranties of any kind. Our aggregate liability is limited to the fees paid in the last 12 months, or EUR 100 if no fees were paid.

You may delete your account at any time. We may suspend or terminate accounts that violate these Terms or the Acceptable Use Policy, with or without prior notice depending on severity.

Where mandatory consumer-protection laws in your country of residence apply, those laws prevail. Otherwise, any dispute arising from these Terms shall be submitted to the courts competent for the defendant's place of residence, or resolved by mutual agreement between the parties.

We may update these Terms. Material changes will be announced at least 14 days in advance via in-product notice and email. Continued use after the effective date constitutes acceptance.
