1. Acceptance of Terms

Welcome to Coffee Tab. These Terms of Service (the "Terms") govern your access to and use of the Coffee Tab browser extension and the related services available at https://cafe.opengspace.com (together, the "Service"), operated by Changsha Oupeng Technology Co., Ltd ("we", "us").

By creating an account, subscribing to a plan, purchasing credits, or otherwise using the Service, you confirm that you: (a) are at least 18 years old; (b) have read, understood, and agree to be bound by these Terms; (c) agree to our Privacy Policy; and (d) have the authority to enter into this agreement on your own behalf or on behalf of your organisation.

Important: if you do not agree to these Terms, please stop using the Service. Continuing to use the Service after we update these Terms means you accept the revised Terms.

2. The Service

2.1 What we provide

Coffee Tab is an AI-powered browser extension that replaces your new tab page with a focused workspace and an "AI cafe" mode, where you can hold conversations with AI characters, send in-app gifts, unlock characters, and interact with cafe scenes. The Service is a digital software-as-a-service product delivered over the internet.

2.2 Nature of the Service

The Service is a digital intangible product. Access is provisioned immediately after your payment is confirmed. Because digital services are delivered instantly, refunds are subject to specific limitations set out in section 7.

2.3 Third-party AI models

The Service relies on third-party AI model providers, including DeepSeek (for conversation generation), OpenAI (for cafe scene artwork generation), and mem0 (for conversation memory). The performance, output quality, and availability of the Service may be affected by the operating status of these providers. We will make reasonable efforts to notify users of material disruptions.

3. Account Registration

3.1 Account creation

Using the AI cafe features requires an account. You must provide accurate and complete information and keep it up to date. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account.

3.2 Account security

• If you notice any unauthorised use of your account, contact us immediately at support@openg.space.
• Do not share your login credentials with any third party.
• Please keep the email address associated with your billing account valid and reachable.

3.3 Business accounts

If you register on behalf of a company or organisation, you represent that you are authorised to enter into this agreement on behalf of that entity.

4. Subscriptions and Credits

4.1 Subscription plans

We offer monthly subscription plans that grant access to the Service together with a monthly allocation of gift credits. Current plans are Espresso (300 credits per month), Latte (800 credits per month), and Reserve (2,000 credits per month). Current plan details and pricing are always shown before checkout at https://cafe.opengspace.com/#membership.

4.2 One-time Gift Pack

In addition to subscriptions, we offer a one-time Gift Pack that adds a fixed number of gift credits to your account. The Gift Pack is a single purchase and does not renew automatically.

4.3 Gift credits

Gift credits are a virtual in-Service unit used to send in-app gifts and unlock certain content. Credits have no cash value, are not transferable, and cannot be exchanged for money. Credits granted by a subscription are issued once per billing period; credits from a Gift Pack are issued on purchase. All credits are combined into a single account balance.
