1. Who may use Symphony
You must be at least 18 years old and located in the United States. You may not use Symphony if you are barred from receiving services under United States export or sanctions law. One account per person; keep your sign-in details private.
2. What Symphony is
Symphony is an AI assistant. Answers are generated by AI models from third-party providers (currently xAI, operated by SpaceX Super Intelligence LLC). You are talking to an AI, not a person. Answers can be inaccurate, incomplete or out of date. Check anything important before relying on it. Symphony does not provide medical, legal, financial or other professional advice.
3. Prices, payment and balance
Before each message Symphony shows the most it can cost; after each answer it shows the actual charge, which will not exceed that maximum. Charges are taken from your prepaid balance, and a message is not sent if its maximum exceeds your balance. A 30-day pass gives the usage stated at purchase for 30 days; unused usage does not carry over and the pass does not renew automatically. Prepaid credit does not expire. Payments are processed by Stripe; we do not receive or store your full card number. Prices may change, but never for a message already sent or a pass already bought.
4. Refunds
If the provider definitely fails, returns an empty answer, or a charge would exceed the maximum shown, the charge is returned to your balance automatically. If it is unclear whether the provider finished (for example a connection that drops mid-answer), the amount is held, not charged, until we check, and you are not charged for an answer you did not receive. For other refund requests, email us within 14 days of the purchase; unused prepaid credit is refundable on request when you close your account. This does not limit any right you have under law.
5. Acceptable use
You agree to follow the Acceptable Use Policy at symphonyai.online/acceptable-use, which forms part of these terms, and the usage policies of the AI providers it names. We may refuse, remove or stop processing content that breaks it, and suspend or close accounts that break it.
6. Your content
You keep your rights in what you type. You give us permission to process it, send it to the AI provider to produce your answer, and store your history until you delete it. As between you and us, you may use the answers you receive, subject to these terms and the law. Others may receive similar answers. You may not use answers to develop or train AI models that compete with Symphony or its providers, or present answers as written by a person.
7. What you may not do
Do not resell, sublicense or give others access to Symphony; access it by automated means other than the interface we provide; probe, overload or bypass its limits or security; or reverse engineer it except where the law allows.
8. Closing your account
You can delete your account at any time in settings. We may suspend or close an account that breaks these terms or is used to cause harm, and will refund unused prepaid credit unless the account was closed for fraud or abuse.
9. Disclaimers
Symphony is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including fitness for a particular purpose, accuracy of answers and uninterrupted service.
10. Limit of liability
To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential damages, and our total liability for any claim relating to Symphony is limited to the amount you paid us in the 12 months before the claim.
11. Changes and law
We may update these terms; the effective date above will change, and material changes will be shown in the app before they apply to you. These terms are governed by the laws of the State of Arizona, without regard to its conflict-of-laws rules.
