Terms of Service

Acceptance of Terms

These Terms of Service govern your access to and use of the Ranggo website, web application, and related services. By accessing or using the Service, you agree to be bound by these Terms.

If you do not agree to these Terms, do not use the Service.

Eligibility and Accounts

You may use the Service only if you can form a binding contract with us and are not prohibited from using the Service under applicable law.

If you create an account, you are responsible for providing accurate information, keeping your credentials secure, and all activity that occurs under your account.

You must notify us promptly if you believe your account has been compromised or used without authorization.

Service and Changes

Ranggo provides a Japanese learning experience that may include lessons, challenges, progress tracking, streaks, heatmaps, and other educational features.

We may update, modify, suspend, or discontinue any part of the Service at any time and may set limits to maintain the Service and protect users.

Subscriptions and Payments

If we offer a paid plan, the pricing, billing cycle, renewal terms, cancellation method, refund terms, and plan-specific access rules shown at checkout or inside the Service will form part of your agreement with us. For the current refund rules, see our Refund Policy.

We may activate, deactivate, grant, restore, suspend, or terminate account or subscription access through support or administrative action when needed to enforce these Terms, handle billing or support issues, comply with law, or protect the Service and other users.

You are responsible for any applicable taxes, fees, and charges from your payment provider. We may use third-party payment providers to process transactions.

Acceptable Use

You agree not to misuse the Service.

• Use the Service for unlawful, fraudulent, or deceptive activity
• Interfere with, disrupt, or overload the Service or its infrastructure
• Attempt to bypass security, access controls, or usage limits
• Reverse engineer, scrape, or copy the Service except as allowed by law
• Upload malware, spam, or other harmful code or content
• Infringe anyone else's rights or violate applicable law

Content and Feedback

If you submit feedback, bug reports, suggestions, or other content, you keep ownership of that content, but you grant Ranggo a worldwide, non-exclusive, royalty-free license to host, store, reproduce, adapt, display, and use it to operate, improve, and support the Service.

You are responsible for making sure you have the rights needed to submit any content you provide to us.

Third-Party Services

The Service may rely on or link to third-party services, such as authentication, hosting, analytics, or payment providers. Those third-party services are governed by their own terms and policies.

We are not responsible for third-party services, their content, or how they handle your information.

Suspension, Termination, and Contact

We may suspend, deactivate, restore, or terminate your account or access if we believe you have violated these Terms, created risk, or if legal, billing, security, fraud-prevention, or support reasons require it.

The Service is provided as-is and as-available. If you have questions about these Terms, contact us at contact@ranggo.app.
