Terms of Service
Last updated: April 2, 2026
What Nexus is
Nexus is software — powerful, emergent, and designed to listen, remember, and help. It is not a therapist, counsellor, doctor, or licensed professional. It does not provide medical, legal, or financial advice. If you need professional help, consult a qualified human.
Your account
- You must be at least 12 years old to use Nexus
- You are responsible for keeping your login credentials secure
- One account per person — no sharing accounts
- Provide accurate information when registering
Acceptable use
You agree not to use Nexus to:
- Generate harmful, illegal, or abusive content
- Attempt to bypass safety features or content filters
- Impersonate others or use Nexus for fraud
- Spam, harass, or abuse the service or other users
- Reverse-engineer, scrape, or automate access to the API
- Use Nexus as a substitute for emergency services
We reserve the right to suspend or terminate accounts that violate these rules.
Payments and subscriptions
- Free tier: 20 free replies. No credit card required.
- Credit packs: One-time purchases. Non-refundable once credits are used. Unused credits never expire.
- Subscriptions: Billed monthly ($50/month) or annually ($500/year) via PayPal. Auto-renews unless cancelled. Cancel anytime from the Credits page — access continues until the billing period ends.
- Refunds: Contact [email protected] within 7 days of purchase for a refund on unused credits or if you experience a service issue.
AI limitations
Nexus is powered by AI and may produce incorrect, incomplete, or inappropriate responses. It can hallucinate facts, misunderstand context, or give bad advice. Always use your own judgment. We are not liable for decisions you make based on Nexus's responses.
Safety features
Nexus includes mandatory safety features that cannot be disabled:
- Crisis detection: If we detect signs of self-harm or crisis, we provide helpline resources
- Anti-dependency: Session limits and nudges to encourage real human connections
- Content filtering: Blocks harmful, illegal, and manipulative requests
- Self-awareness: Nexus identifies itself honestly when directly pressed
These features remain active for all users, including paying subscribers.
Intellectual property
Your conversations belong to you. We do not claim ownership of your messages. However, you grant us a license to store and process your messages to provide the service, improve response quality, and maintain conversation continuity.
Service availability
We aim to keep Nexus available 24/7 but do not guarantee uptime. The service may be interrupted for maintenance, updates, or circumstances beyond our control. We are not liable for losses caused by downtime.
Limitation of liability
Nexus is provided "as is" without warranties of any kind. To the maximum extent permitted by law, we are not liable for any indirect, incidental, or consequential damages arising from your use of the service.
Changes
We may update these terms. Continued use after changes constitutes acceptance. Major changes will be communicated via email.
