Terms of Service

Welcome to Rivoii. These Terms of Service (“Terms”) govern your access to and use of Rivoii's websites, applications, software, products, AI-powered features, and other services that link to these Terms (collectively, the “Services”).

By accessing or using the Services, you agree to be bound by these Terms. If you do not agree to these Terms, you must not access or use the Services.

These Terms apply to the Rivoii website, Rivoii Learn, and any current or future Rivoii product or service that references these Terms. A particular product may include additional terms. If product-specific terms conflict with these Terms, the product-specific terms will control for that product to the extent of the conflict.

You must be at least 13 years old, or the minimum age required to use the Services in your jurisdiction, whichever is greater.

If you are under the age of majority where you live, you may use the Services only with the involvement and permission of a parent or legal guardian, or through a school or other organization that is authorized to provide access, where required by applicable law.

If you use the Services on behalf of a business, school, or other organization, you represent that you have authority to bind that organization to these Terms. In that case, “you” includes both you and the organization.

Rivoii develops digital products and services, including educational and AI-powered experiences. Rivoii Learn is planned as Rivoii's first product, and additional products, features, and services may be introduced over time.

Some descriptions in these Terms address functionality that may not yet be available. Those provisions apply only when you use the relevant functionality.

We may add, modify, improve, suspend, or discontinue any part of the Services. We will provide notice where required by applicable law or where a change materially affects an active paid service.

Some Services may require an account. You agree to provide accurate, current, and complete information and to keep that information updated.

You are responsible for safeguarding your login credentials and for activity that occurs through your account. You must not share credentials in a way that compromises account security or allows unauthorized access.

Notify us promptly at hello@rivoii.com if you believe your account has been accessed or used without authorization.

You may not create an account using false information, impersonate another person or organization, or create an account after we have suspended or terminated your access unless we give you permission.

You may use the Services only for lawful purposes and in accordance with these Terms. You must not use, attempt to use, or help another person use the Services to:

• violate any applicable law, regulation, court order, or legal right;
• harm, threaten, harass, exploit, defraud, or impersonate another person;
• create, upload, request, or distribute unlawful, abusive, hateful, sexually exploitative, deceptive, or violent content;
• infringe intellectual-property, privacy, publicity, confidentiality, or other rights;
• distribute malware, malicious code, spam, phishing messages, or harmful material;
• gain unauthorized access to accounts, systems, networks, data, or security controls;
• interfere with, overload, disrupt, damage, or circumvent the Services or their protections;
• scrape, crawl, harvest, or extract data through automated means except where expressly permitted;
• reverse engineer, decompile, disassemble, or attempt to discover source code, except where law does not allow this restriction;
• use outputs or features to make unlawful or high-impact decisions about another person without appropriate human review; or
• represent AI-generated material as human-created where doing so would be deceptive or unlawful.

We may investigate suspected misuse and take reasonable action to protect users, Rivoii, third parties, and the Services.

Some Services may allow you to submit, upload, create, transmit, or store text, prompts, files, documents, images, feedback, or other material (“User Content”).

As between you and Rivoii, you retain ownership of your User Content. You are responsible for your User Content and for ensuring that you have the rights and permissions needed to provide it to the Services.

You grant Rivoii a worldwide, non-exclusive, royalty-free license to host, store, reproduce, process, transmit, display, and otherwise use your User Content only as reasonably necessary to operate, provide, secure, maintain, and improve the Services; comply with law; enforce these Terms; and follow your instructions.

This license continues for as long as your User Content is stored or used for those purposes. Where technically and legally possible, it ends when the User Content is deleted from our active systems, although limited copies may remain temporarily in backups, security records, or records we are legally required to retain.

You should not upload confidential, sensitive, or rights-restricted material unless the relevant Service is designed to process it and you are authorized to provide it.

We welcome ideas, suggestions, and feedback. If you provide feedback about the Services, you grant Rivoii a worldwide, perpetual, irrevocable, royalty-free license to use, reproduce, modify, publish, and otherwise exploit that feedback for any lawful purpose without compensation or obligation to you.

This section does not give Rivoii ownership of your User Content or personal information.

Educational content, explanations, recommendations, quizzes, scores, and AI-generated materials provided through the Services are intended to support learning. They do not guarantee academic results, admission, certification, employment, or any particular outcome.

Users remain responsible for following the academic-integrity rules, examination rules, acceptable-use policies, and other requirements of their school, university, employer, or learning provider.

Educators, schools, parents, and learners should apply appropriate human judgment when using the Services for instruction, assessment, grading, or decisions that affect a learner.

The Services, including their software, interfaces, designs, branding, text, graphics, audiovisual material, databases, models, features, and other content provided by Rivoii, are owned by Rivoii or its licensors and are protected by applicable intellectual-property and other laws.

Subject to these Terms, Rivoii grants you a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable right to access and use the Services for their intended purposes.

Except for that limited right, these Terms do not transfer ownership or intellectual-property rights to you. You may not use Rivoii's names, logos, branding, or other protected materials without prior written permission.

The Services may contain links to, integrations with, or content from third-party websites, applications, platforms, models, payment providers, or other services.

Third-party services are controlled by their respective providers and may be governed by separate terms and privacy policies. Rivoii is not responsible for third-party services or for loss or harm caused by your use of them, except to the extent responsibility cannot be excluded under applicable law.

We may offer beta, preview, early-access, or experimental features. These features may be incomplete, contain errors, change without notice, or be discontinued.

Unless we state otherwise, you should not rely on such features for production, safety-critical, or other important uses. Additional conditions may apply to testing programs.

We work to keep the Services reliable, but we do not guarantee that they will always be available, uninterrupted, secure, or error-free.

Access may be affected by maintenance, updates, technical failures, internet conditions, third-party services, security incidents, legal requirements, or events beyond our reasonable control.

We may set or modify usage limits, storage limits, feature availability, supported devices, and technical requirements where reasonably necessary to operate and protect the Services.

You may stop using the Services at any time. Where account controls are available, you may request account closure through those controls or by contacting us.

We may restrict, suspend, or terminate access if we reasonably believe that:

• you materially or repeatedly violated these Terms;
• your use creates a security, legal, or safety risk;
• your account is involved in fraud, abuse, or unauthorized activity;
• payment for a paid Service is overdue or reversed; or
• suspension or termination is required by law or necessary to protect the Services or others.

Where appropriate and legally permitted, we will provide notice and a reasonable opportunity to address the issue before termination. We may act immediately in urgent, serious, or repeated cases.

Provisions that by their nature should survive termination will remain effective, including provisions concerning ownership, licenses already granted where necessary, disclaimers, limitations of liability, and amounts owed.

Our Privacy Policy explains how Rivoii collects, uses, discloses, retains, and protects personal information in connection with the Services.

To the fullest extent permitted by applicable law, the Services are provided on an “as is” and “as available” basis without warranties of any kind, whether express, implied, or statutory.

To the fullest extent permitted by applicable law, Rivoii disclaims implied warranties of merchantability, fitness for a particular purpose, satisfactory quality, non-infringement, quiet enjoyment, and warranties arising from course of dealing.

We do not warrant that the Services or any content or Output will be accurate, complete, reliable, current, secure, uninterrupted, error-free, or suitable for your needs.

Some jurisdictions do not allow certain warranty exclusions. In those jurisdictions, these exclusions apply only to the extent permitted by law.

To the fullest extent permitted by applicable law, Rivoii and its suppliers, licensors, service providers, and representatives will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenue, opportunities, goodwill, data, or use, arising from or relating to the Services or these Terms.

To the fullest extent permitted by applicable law, Rivoii's total aggregate liability arising from or relating to the Services or these Terms will not exceed the greater of:

• the amount you paid to Rivoii for the Service giving rise to the claim during the twelve months before the event giving rise to liability; or
• one hundred United States dollars (US$100).

These limitations apply regardless of the legal theory and even if a remedy fails of its essential purpose. They do not limit liability that cannot lawfully be limited or excluded, including liability for fraud, willful misconduct, or any liability that applicable law requires to remain unlimited.

If you use the Services on behalf of a business, school, or other organization, that organization will, to the extent permitted by law, defend and indemnify Rivoii and its representatives against third-party claims, losses, liabilities, damages, judgments, costs, and reasonable legal fees arising from:

• its User Content;
• its unlawful or unauthorized use of the Services;
• its material violation of these Terms; or
• its infringement or violation of another person's rights.

This section does not require indemnification for matters caused by Rivoii's own unlawful conduct and does not apply where prohibited by applicable law.

By using the Services, you agree that we may provide service-related notices and communications electronically, including through email, in-product messages, or publication within the Services.

Marketing communications will be sent in accordance with applicable law. You may unsubscribe from marketing emails using the method provided in those messages. You may still receive essential account, security, transaction, and service-related communications.

We may update these Terms as the Services evolve, our practices change, or legal requirements develop.

When we update these Terms, we will revise the “Last updated” date. If a change is material, we may provide additional notice through the Services, by email, or by another appropriate method.

Unless a different date is stated, updated Terms become effective when published. Your continued use of the Services after the effective date means you accept the updated Terms, except where applicable law requires a different form of consent.
