Terms governing the Wisteria mobile application, website, AI companions, stories, and related services

Effective date	September 22, 2026
Provider	Vimo Technology Co., Ltd.

These Terms of Use (the “Terms”) are a binding agreement between you and Vimo Technology Co., Ltd. (“Vimo,” “we,” “us,” or “our”). They govern your access to and use of the Wisteria mobile application, wisteria.chat, AI companions, stories, content, features, subscriptions, and related services (collectively, the “Services”).

Please read these Terms carefully. By downloading, accessing, purchasing, or using the Services, you agree to these Terms and acknowledge our Privacy Policy. If you do not agree, do not use the Services. You must be at least 18 years old to use Wisteria.

1 Eligibility and accounts

You may use the Services only if you are at least 18 years old, have legal capacity to enter into these Terms, and are not barred from using the Services under applicable law. By using Wisteria, you represent and warrant that you meet these requirements. Wisteria is available to everyone who satisfies these requirements and is designed with the LGBTQ+ community in mind.

You may create an account using Sign in with Apple and may provide profile information such as a name, username, display name, date of birth, gender identity, sexual orientation, and pronouns. You must provide accurate information, protect access to your account and device, and promptly notify us of suspected unauthorized use. You are responsible for activity conducted through your account, except to the extent caused by our failure to use reasonable security measures.

The Services are not directed to minors. We may request age information or take other reasonable steps to verify eligibility. We may restrict or terminate an account if we reasonably believe the user is under 18 or has misrepresented age.

2 The Wisteria service and AI disclosure

Wisteria provides fictional, AI-powered companions, conversations, and stories. AI companions are software, not people, professionals, or sentient beings. Their messages are generated automatically and do not represent the opinions, promises, knowledge, or advice of Vimo or any real person.

Generative AI can produce responses that are inaccurate, incomplete, offensive, biased, unexpected, repetitive, or otherwise unsuitable. Wisteria may support mature or romantic conversations when selected by an adult user, but the availability of a feature does not mean that every generated response is appropriate, accurate, or endorsed by us. You are responsible for exercising judgment and for how you use or rely on generated content.

The Services may change over time. We may add, remove, limit, suspend, or modify companions, stories, models, memory duration, features, or access tiers. We do not guarantee that any particular companion, conversation, memory, feature, or content will remain available.

3 Safety and professional advice

Wisteria is for entertainment, creative expression, and companionship. It is not a medical, mental-health, therapy, counseling, legal, financial, or other professional service. AI responses are not professional advice and must not be used to diagnose, treat, or prevent a condition or to make medical, legal, financial, emergency, or safety-critical decisions.

Wisteria is not a crisis-response or emergency service and does not monitor conversations in real time. If you believe you or another person may be in immediate danger, contact local emergency services or an appropriate crisis resource. Do not delay seeking qualified human assistance because of anything generated by Wisteria.

4 User content and conversation data

“User Content” means information or material you submit, upload, transmit, create, or make available through the Services, including profile information, prompts, messages, reports, photos, audio, and other files. You retain any rights you have in your User Content.

You grant Vimo a worldwide, non-exclusive, royalty-free, sublicensable, and transferable license to host, store, reproduce, modify, format, transmit, display, analyze, and otherwise use User Content only as reasonably necessary to provide, secure, maintain, moderate, personalize, support, develop, and improve the Services; comply with law; and enforce these Terms. This license lasts for as long as needed for those purposes, subject to the deletion and retention provisions in our Privacy Policy. It does not give us ownership of your User Content.

You represent that you have the rights and permissions necessary to submit User Content and that doing so will not violate law, these Terms, or another person’s rights. Do not submit confidential information belonging to another person or unnecessary personal information about third parties.

Conversation history may be stored to provide continuity and memory. The amount or duration of available history may depend on whether you use a free or paid account. You should not rely on Wisteria as the sole repository for any information you wish to preserve.

5 AI output

“Output” means content generated by the Services in response to User Content. As between you and Vimo, and to the extent permitted by applicable law, you may use Output generated specifically for you for personal, lawful purposes. Outputs may not be unique, and other users may receive the same or similar content. We do not represent that Output is protectable by intellectual-property law or free from third-party rights.

Vimo retains all rights in the Services and in Vimo-created or licensed companions, character designs, names, stories, interfaces, prompts, systems, branding, and other materials. Your permitted use of a generated conversation does not transfer ownership of those underlying materials or allow you to imply endorsement, impersonate Vimo, or commercially exploit a Wisteria companion or brand without written permission.

6 Acceptable use

You must use the Services lawfully and respectfully. You may not use the Services to:

• create, solicit, sexualize, groom, exploit, endanger, or depict minors in sexual or abusive contexts, including fictional or AI-generated depictions;

• create or distribute non-consensual intimate imagery, sexual content involving a real person without permission, sextortion material, or content that facilitates sexual violence or exploitation;

• threaten, harass, stalk, bully, defame, discriminate against, or incite hatred or violence toward any person or protected group;

• encourage suicide, self-harm, eating-disorder behavior, terrorism, violent extremism, or imminent physical harm;

• facilitate illegal conduct, fraud, trafficking, abuse, weapons offenses, unauthorized surveillance, or evasion of law enforcement;

• impersonate another person, misrepresent AI content as authentic human communication where that would be deceptive, or infringe privacy, publicity, intellectual-property, or other rights;

• upload malware, interfere with security or operation, probe vulnerabilities, bypass safeguards or access controls, or obtain unauthorized access;

• scrape, crawl, harvest, benchmark for competitive model development, reverse engineer, decompile, extract model components, or use automated means to access the Services except with our written permission;

• use Output as professional advice or in high-impact decisions concerning employment, housing, credit, education, insurance, health care, legal rights, or access to essential services; or

• violate applicable third-party terms, including platform, telecommunications, and AI-provider acceptable-use requirements.

This list is not exhaustive. We may investigate suspected violations, remove or restrict content, limit features, preserve evidence, report conduct where legally required or reasonably necessary to protect safety, and suspend or terminate accounts. Automated moderation may make mistakes. You may report content or contact us if you believe an enforcement decision should be reviewed.

7 Moderation and reporting

We use automated systems and may use human review to detect abuse, enforce these Terms, investigate reports, prevent fraud, protect users, and improve safety. We are not obligated to monitor every interaction and cannot guarantee that all objectionable or harmful content will be detected or removed. Reports must be made in good faith and must not be used to harass other users or manipulate enforcement.

8 Subscriptions, free trials, and Apple billing

Wisteria offers a free experience and may offer auto-renewing subscriptions, introductory offers, or free trials. The price, billing period, trial length, included features, and any eligibility conditions will be shown before purchase. Prices and included features may change. A price change will apply only as permitted by Apple and applicable law.

Purchases made through the Apple App Store are billed to your Apple ID and are governed by Apple’s applicable payment and subscription terms. Unless canceled at least 24 hours before the end of the current period, an auto-renewing subscription may renew and your Apple ID may be charged. You can manage or cancel a subscription in your Apple account settings. Deleting Wisteria or deleting your Wisteria account does not automatically cancel an Apple subscription.

Apple handles App Store billing, cancellation, refund, and payment disputes. Except where required by law, Vimo cannot issue refunds for purchases processed by Apple. If a free trial converts to a paid subscription, the displayed subscription price will be charged unless you cancel before the trial ends. Trial eligibility may be limited by Apple or to one trial per user or account.

9 License and Apple terms

The Wisteria app is licensed, not sold. Subject to these Terms, Vimo grants you a limited, personal, revocable, non-exclusive, non-transferable, and non-sublicensable right to access and use the Services for lawful, personal purposes.

The Apple Standard Licensed Application End User License Agreement governs your license to the iOS app unless a valid custom license is presented through Apple. These Terms govern Wisteria accounts, content, subscriptions, and Services in addition to that license. If there is a conflict concerning the app license, the Apple Standard EULA controls to the extent of the conflict.

10 Third-party services and BytePlus

The Services rely on third parties, including Apple, Firebase, BytePlus, RevenueCat, Amplitude, Firebase Analytics, Crashlytics, Meta, and other infrastructure, analytics, safety, communications, and attribution providers. Third-party services may be governed by their own terms and privacy notices. We are not responsible for third-party services that we do not control.

Wisteria uses BytePlus AI models and services supplied by ByteDance-affiliated entities. Your prompts and related context may be transmitted to and processed by BytePlus to generate responses, subject to our agreements with the provider and as described in the Privacy Policy. By using AI features, you agree to comply with applicable BytePlus acceptable-use restrictions and acknowledge that BytePlus technology is involved. Nothing in these Terms makes you a direct party to a separate enterprise agreement between Vimo and BytePlus.

11 Ownership and feedback

The Services, software, models and model configurations, interfaces, designs, text, graphics, logos, trademarks, companions, stories, and other Vimo or licensed content are protected by intellectual-property and other laws. Except for the limited rights expressly granted in these Terms, Vimo and its licensors reserve all rights.

If you provide ideas, suggestions, or feedback about the Services, you grant Vimo a perpetual, worldwide, irrevocable, royalty-free right to use them without restriction or compensation, provided that this does not authorize us to identify you publicly without permission.

12 Account deletion, suspension, and termination

You may delete your account and associated data using Delete Account in Settings or by emailing us. Deletion is subject to limited retention permitted or required for security, fraud prevention, legal compliance, dispute resolution, and enforcement, as described in the Privacy Policy. Account deletion may be irreversible and may remove access to conversation history and other content.

You may stop using the Services at any time. We may suspend or terminate access, remove content, or limit features if we reasonably believe you violated these Terms, created legal or safety risk, failed to pay applicable charges, or used the Services in a way that could harm users, Vimo, or third parties. Where appropriate and legally required, we will provide notice or an opportunity to appeal. Sections that by their nature should survive termination will survive, including ownership, disclaimers, liability limits, indemnity, dispute resolution, and accrued payment obligations.

13 Disclaimers

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICES AND ALL CONTENT AND OUTPUT ARE PROVIDED “AS IS” AND “AS AVAILABLE.” VIMO DISCLAIMS ALL EXPRESS, IMPLIED, AND STATUTORY WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, AVAILABILITY, SECURITY, AND QUIET ENJOYMENT. WE DO NOT WARRANT THAT THE SERVICES WILL BE UNINTERRUPTED, ERROR-FREE, SAFE, ACCURATE, OR SUITABLE FOR YOUR PURPOSES, OR THAT CONTENT WILL BE PRESERVED.

Some jurisdictions do not allow certain warranty exclusions. In those jurisdictions, the exclusions apply only to the extent permitted by law and do not affect non-waivable consumer rights.

14 Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, VIMO AND ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, CONTRACTORS, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, GOODWILL, DATA, CONTENT, OR BUSINESS OPPORTUNITY, ARISING FROM OR RELATED TO THE SERVICES, EVEN IF ADVISED THAT SUCH DAMAGES WERE POSSIBLE.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE TOTAL LIABILITY OF VIMO AND THE OTHER VIMO PARTIES FOR ALL CLAIMS ARISING FROM OR RELATING TO THE SERVICES OR THESE TERMS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID VIMO THROUGH THE SERVICES DURING THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM OR (B) US$100.

These limitations do not apply to liability that cannot legally be excluded or limited. The limitations apply even if a remedy fails of its essential purpose.

15 Indemnification

To the extent permitted by law, you agree to defend, indemnify, and hold harmless Vimo and its affiliates, officers, directors, employees, contractors, licensors, and service providers from claims, liabilities, damages, judgments, losses, costs, and reasonable attorneys’ fees arising from your User Content, your unlawful or prohibited use of the Services, or your material violation of these Terms or another person’s rights. This obligation does not apply to the extent a claim results from Vimo’s own unlawful conduct, negligence, or willful misconduct.

16 Governing law and informal dispute resolution

These Terms are governed by the laws of the State of California and applicable federal law, without regard to conflict-of-law rules, except that mandatory consumer protections in your place of residence continue to apply.

Before filing a formal claim, you and Vimo agree to attempt to resolve the dispute informally for 30 days. A notice must describe the claimant, the relevant account, the facts, the requested relief, and a good-faith calculation of any monetary demand. Send notices to wisteriasupport@gmail.com with the subject “Legal Dispute Notice.” This requirement does not prevent either party from seeking urgent injunctive relief or filing an eligible small-claims case.

17 Binding individual arbitration and class-action waiver

PLEASE READ THIS SECTION CAREFULLY. IT AFFECTS YOUR LEGAL RIGHTS.

Except for disputes that qualify for small-claims court, claims seeking only temporary or preliminary injunctive relief, and claims concerning infringement or misuse of intellectual-property rights, any dispute arising from or relating to these Terms or the Services will be resolved by binding individual arbitration administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules. The Federal Arbitration Act governs this arbitration agreement.

Arbitration will occur by video, telephone, written submissions, or in the county where you live, unless the parties agree otherwise. Vimo will pay arbitration fees to the extent required by the AAA rules or applicable law. The arbitrator may award the same individual remedies a court could award and will issue a reasoned written decision.

YOU AND VIMO AGREE THAT EACH MAY BRING CLAIMS ONLY IN AN INDIVIDUAL CAPACITY, NOT AS A PLAINTIFF, CLASS MEMBER, OR REPRESENTATIVE IN A CLASS, CONSOLIDATED, COLLECTIVE, OR REPRESENTATIVE ACTION. THE ARBITRATOR MAY NOT COMBINE CLAIMS OF DIFFERENT USERS WITHOUT ALL PARTIES’ CONSENT. YOU AND VIMO WAIVE THE RIGHT TO A JURY TRIAL TO THE EXTENT PERMITTED BY LAW.

You may opt out of arbitration by emailing wisteriasupport@gmail.com within 30 days after you first accept these Terms. Use the subject “Arbitration Opt-Out” and include your full name, the email or private relay address associated with your account, and an unambiguous statement that you opt out. Opting out will not affect your access to Wisteria. If you validly opt out, or if this arbitration section is found unenforceable as to a dispute, exclusive jurisdiction and venue will lie in the state or federal courts located in California, subject to any non-waivable right to bring a claim elsewhere.

If any part of this arbitration section is unenforceable, it will be severed and the remainder will remain effective, except that if the class-action waiver is unenforceable as to a particular claim or request for relief, that claim or request must proceed in court and the remaining arbitrable claims will be stayed pending its resolution.

18 Changes to these Terms

We may update these Terms to reflect changes in the Services, law, safety practices, or business operations. We will post the updated Terms and revise the effective date. If changes materially reduce your rights or increase your obligations, we will provide reasonable advance notice through the Services, email, or another appropriate method when required by law. Your continued use after the effective date of updated Terms constitutes acceptance, except where applicable law requires a different form of consent.

19 General terms

These Terms, the Privacy Policy, the Apple Standard EULA as applicable, and any purchase terms shown at checkout constitute the agreement between you and Vimo concerning the Services. If a provision is unenforceable, it will be enforced to the maximum lawful extent and the remainder will continue. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our written consent; we may assign them in connection with a merger, acquisition, financing, reorganization, sale of assets, or by operation of law. We are not liable for delays or failures caused by events beyond our reasonable control.
