1. Definitions
- Service — the Sibyl Quantitative forecasting platform, including the website at sibyl-ai.com, the mobile-optimized progressive web app, the Sibyl Take AI synthesis output, multi-horizon forecast data, the auto-trade integration, and any related software, content, or APIs.
- Account — your personal user record on the Service, identified by your email address.
- Subscription — a recurring paid plan that unlocks access to the paid features of the Service (currently "Sibyl Pro" at $39.00 USD per month after a 14-day free trial).
- Content — any forecast, signal, AI synthesis, chart, data point, or other information produced or displayed by the Service.
- Auto-Trade — the optional feature that, when configured by you, places real orders through your linked third-party brokerage (Alpaca Securities LLC) based on Sibyl signals.
2. Eligibility
You must be at least 18 years old and legally able to enter into a binding contract under the laws of your jurisdiction. You must not be (a) located in, or a resident of, any country or region subject to U.S. sanctions; (b) on any U.S. government list of prohibited or restricted parties; or (c) prohibited from receiving the Service under applicable law.
You may only create one Account per person. You are responsible for keeping your Account credentials secure and for all activity that occurs under your Account.
3. Beta Status
The Service is currently a beta product. Models, prompts, pricing, forecast methodologies, and user-interface elements are in active development and may change without notice. Forecasts and signals may be inaccurate, stale, or wrong. Backtest accuracy and historical track records are not guarantees of future performance. You acknowledge that you are using a beta product and that any output you see should be treated as exploratory.
4. Not Financial Advice
THIS SECTION IS CRITICAL. PLEASE READ CAREFULLY.
Sibyl is a research and analytics tool. Sibyl is not a registered investment advisor (RIA), broker-dealer, futures commission merchant, commodity trading advisor, or financial institution under any jurisdiction. Sibyl does not provide investment advice, personalized recommendations, or any solicitation to buy, sell, or hold any security, derivative, cryptocurrency, or other asset.
All forecasts, signals, the Sibyl Take AI synthesis, multi-horizon predictions, consensus tiers, expected-move calculations, sector-routing outputs, and any other Content produced by the Service are informational only. They are not, and should not be interpreted as:
- Investment advice
- A recommendation to buy, sell, or hold any security or asset
- An offer or solicitation
- A guarantee of future performance
- A substitute for the judgment of a licensed financial professional
You acknowledge and agree that all trading decisions are made solely by you, based on your own research, risk tolerance, financial situation, and consultation with licensed professionals where appropriate. You assume full responsibility for any gain or loss arising from your use of the Service. You should consult a licensed financial advisor, tax professional, and/or attorney before acting on anything you see on the Service.
The use of historical data, statistical models, machine-learning predictions, and AI synthesis in producing Content does not constitute investment advice. Past performance, including backtested performance, is not a guarantee or projection of future results. All trading involves risk, including the possibility of total loss of principal. Options trading carries additional risks including but not limited to time decay (theta), implied-volatility crush, and assignment risk; you may lose 100% of premium paid quickly.
If you are not comfortable with these risks, you must not use the Service to make trading decisions.
5. Auto-Trade Feature
The Service offers an optional Auto-Trade feature that, when you enable and configure it, places real orders in your linked Alpaca Securities LLC brokerage account based on signals produced by the Service.
You acknowledge:
- Auto-Trade is opt-in. By default, no orders are placed.
- You are solely responsible for configuring Auto-Trade, including position sizing, tickers in scope, exit ladder thresholds, and any other parameters.
- The Service executes orders based on signals it produces. The Service does not guarantee that any order will be filled, that fills will occur at any particular price, or that the orders themselves will be profitable.
- Real money is at risk. Orders placed via Auto-Trade are real orders in a real brokerage account, regulated by your brokerage's terms and the rules of the relevant exchanges and regulators.
- You assume full responsibility for all trades placed by Auto-Trade.
- Sibyl is not a broker, market maker, or party to any trade. The actual order routing, execution, custody, and clearing is performed by Alpaca Securities LLC and its clearing partners, subject to Alpaca's separate terms of service.
- If you do not understand how Auto-Trade works or are not comfortable with its risks, you should not enable it.
6. Subscriptions and Auto-Renewal
6.1 Subscription terms
The Service offers a paid Subscription ("Sibyl Pro") at $39.00 USD per month. New subscribers receive a 14-day free trial, during which time you will not be charged. At the end of the 14-day free trial, your payment method will be automatically charged $39.00 USD, and your Subscription will renew monthly thereafter at the same rate unless you cancel before the renewal date.
6.2 Auto-renewal disclosure (California Bus. & Prof. Code § 17602)
By starting a Subscription, you authorize Sibyl, through its payment processor Stripe, to automatically charge your payment method $39.00 USD per month until you cancel. Your Subscription will continue indefinitely on a monthly basis until canceled.
You may cancel at any time in your Account settings or by visiting the Stripe-hosted billing portal. Cancellation is effective at the end of the current billing period; you retain access to paid features until that date. Sibyl does not provide prorated refunds for partial months unless required by law.
You will receive an email reminder approximately 7 days before each renewal charge to the email address on file.
6.3 Pricing changes
We may change the Subscription price from time to time. We will notify you by email at least 30 days before any price change takes effect. If you do not agree to the new price, you may cancel your Subscription before the effective date. Continued use of the Service after the price change constitutes acceptance.
6.4 Free trial eligibility
The 14-day free trial is available to first-time subscribers only. Attempts to obtain multiple free trials by creating additional accounts may result in suspension and forfeiture of the trial. We reserve the right to limit free trial availability at our discretion.

13. Governing Law; Arbitration; Class-Action Waiver
13.1 Governing law
These Terms are governed by the laws of the State of California, U.S.A., without regard to its conflict-of-law principles. The United Nations Convention on Contracts for the International Sale of Goods does not apply.
13.2 Arbitration
Any dispute, claim, or controversy arising out of or relating to these Terms or the Service ("Dispute") will be resolved by binding, individual arbitration administered by the American Arbitration Association ("AAA") under its Commercial Arbitration Rules and the AAA's Consumer Arbitration Rules where applicable. The arbitration will be conducted in Los Angeles County, California. The arbitrator's decision will be final and binding, and judgment on the award may be entered in any court of competent jurisdiction.
13.3 Class-action waiver
YOU AND SIBYL EACH WAIVE THE RIGHT TO BRING OR PARTICIPATE IN ANY CLASS ACTION, CLASS ARBITRATION, OR REPRESENTATIVE PROCEEDING ARISING OUT OF OR RELATED TO THESE TERMS OR THE SERVICE. THE ARBITRATOR MAY NOT CONSOLIDATE MORE THAN ONE PERSON'S CLAIMS AND MAY NOT OTHERWISE PRESIDE OVER ANY FORM OF A REPRESENTATIVE OR CLASS PROCEEDING.
13.4 30-day opt-out right
You may opt out of the arbitration agreement in Section 13.2 and the class-action waiver in Section 13.3 by sending written notice to legal@sibyl-ai.com within 30 days of first accepting these Terms. Opting out does not affect any other portion of these Terms.
13.5 Exceptions
Either party may bring an individual action in small-claims court. Either party may seek injunctive or other equitable relief in court to prevent infringement of intellectual property rights or unauthorized use of the Service.
14. Termination
You may terminate your Account at any time by canceling your Subscription (if applicable) and replying "delete" to any account-related email, or by contacting support@sibyl-ai.com. Upon termination, your right to use the Service ends immediately. Sections that by their nature should survive termination will survive (including without limitation Sections 4, 8, 10, 11, 12, and 13).
We may suspend or terminate your Account at any time, with or without notice, for any reason, including without limitation if you violate these Terms, if we are required to do so by law, or if we discontinue the Service.
15. Modifications
We may modify these Terms from time to time. Material changes will be communicated by email to the address on file at least 14 days before the changes take effect. Your continued use of the Service after the effective date constitutes acceptance of the modified Terms. If you do not agree to the modified Terms, you must stop using the Service.
16. Miscellaneous
- Entire agreement. These Terms, together with the Privacy Policy, Refund Policy, and Risk Disclosure, constitute the entire agreement between you and Sibyl regarding the Service.
- Severability. If any provision of these Terms is held to be invalid or unenforceable, the remaining provisions will continue in full force and effect.
- No waiver. Sibyl's failure to enforce any provision is not a waiver of its right to do so later.
- Assignment. You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of all or substantially all of our assets, with notice to you.
- Force majeure. Sibyl is not liable for any failure or delay in performance caused by events beyond our reasonable control, including but not limited to acts of God, natural disasters, war, terrorism, labor disputes, governmental actions, or failures of third-party infrastructure (cloud providers, internet service providers, brokerages).
- Headings. Section headings are for convenience only and do not affect interpretation.
