Terms of Use

Last updated: October 7, 2026

1. Acceptance of these terms and eligibility

These Terms of Use ("Terms") are an agreement between you and the operator of the SeasonalQuant service ("SeasonalQuant", "we" and "us"). They apply to our website and to the SeasonalQuant app, which are served from the same address (together, the "Service"). "You" means anyone who visits the site or uses the app.

By creating an account, signing in, or otherwise using the Service, you agree to these Terms. If you do not agree, do not use the Service. Our Privacy Policy explains how we handle your personal data and forms part of these Terms.

You must be at least 18 years old, and able to enter into a binding contract where you live, to use the Service. If you use the Service on behalf of a company or other organization, you confirm that you have authority to accept these Terms for it, and "you" includes that organization.

2. The Service and our plans

SeasonalQuant is a web platform for quantitative analysis of seasonal spreads in exchange-traded commodity futures (grains, softs, meats, energy and metals). It includes a screener, a spread builder, a window optimizer, backtesting, a Monte Carlo trade forecaster, and historical performance views. It covers commodity futures only, and it does not connect to any brokerage account or place orders.

We offer three plans:

• Free. Corn futures data only, up to 5 years of historical data, and 3 Window Optimizer runs, 3 Trade Forecaster runs and 3 entry and take-profit analyses per month.
• Basic ($49.95 per month when billed monthly). All futures data in the Service, up to 10 years of historical data, 10 runs of each of those features per month, and custom trades.
• Professional ($59.95 per month when billed monthly). All futures data in the Service, up to 30 years of historical data, unlimited runs, a custom backtesting period, and saved configurations.

Paid plans can be billed monthly or annually; annual billing is discounted ("Save 50%" on our pricing page). The pricing page in the app shows current prices, features and limits, and takes precedence over this summary if they differ.

• Monthly allowances reset each usage period, and unused runs do not carry over.
• If a run fails because of an error on our side, we return it to your allowance.
• When you change plans, your allowance resets to the new plan's limits.

3. Accounts and security

You need an account to use the app. You can sign up with an email address and password, or with Google Sign-In.

• Email sign-up. Your email address is your username. Passwords must be at least 8 characters long. You must confirm your email address, using the link we send you, before you can sign in.
• Google Sign-In. We use the email address and name Google provides, which Google has already verified. If an account with that email already exists, signing in with Google links to it. Google's own terms also apply.
• Accurate information. Keep your email address current. We send account and subscription notices there.
• One person per account. Each account is for one individual. Do not share your sign-in details or use one subscription for several people.
• Keeping your account safe. You are responsible for securing your password and Google account, and for activity under your account. Tell us at once at support@seasonal-quant.com if you suspect unauthorized use.
• Security measures. We rate-limit sign-in and other sensitive requests. We may block sign-in attempts, require a password reset, or temporarily lock an account if we see suspicious activity.

4. Subscriptions, billing and cancellation

Payments

Payments are processed by our payment processor, Stripe. You enter your card details on Stripe's checkout page and manage your subscription in Stripe's customer portal, linked from your profile in the app. We never see or store your full card number. Stripe's terms also apply. Promotion codes apply only on the terms stated with them.

Automatic renewal

Paid plans renew automatically. When you subscribe, you authorize us, through Stripe, to charge your payment method at the start of each monthly or annual billing period until you cancel, at the price shown at checkout. We email you when a renewal payment succeeds or fails.

Failed payments

If a renewal payment fails, we will email you to update your payment method, and Stripe may retry the charge. If payment is not made, your paid subscription may end and your account will move to the Free plan.

Changing plans

You can upgrade from Free on the pricing page in the app. You can switch between Basic and Professional, or between monthly and annual billing, in the Stripe customer portal. When you switch, the full price of the new plan or billing period is charged and the unused part of your previous period is not credited or recalculated. The portal shows the amount before you confirm.

Cancellation

• You can cancel at any time, either in the app or through the Stripe customer portal.
• Your cancellation takes effect at the end of your current billing period. You keep access to your paid plan until then, and you will not be charged again.
• Until the period ends, you can undo the cancellation in the portal.
• When your paid subscription ends, your account moves to the Free plan automatically and the Free plan limits then apply. Features that are only in paid plans, such as data beyond the Free plan, will no longer be available.

Refunds

Payments are generally non-refundable. If you think you should get a refund, for example because you were charged by mistake or the Service did not work as described, email us at support@seasonal-quant.com from the address on your account and explain the reason. We review each request individually and will reply with our decision. Nothing in these Terms limits any right you have under consumer protection laws that apply to you, including any statutory right to withdraw from a contract.

Price changes

We may change our prices. A price change does not affect a billing period you have already paid for. We will notify you by email or in the app before a new price applies to your next renewal. If you do not want to pay the new price, you can cancel before the renewal date.

Taxes

Prices do not include taxes unless we say they do. Where applicable law requires it, sales tax, VAT or similar taxes may be added at checkout, and you are responsible for paying them.

5. Acceptable use

You may use the Service only for your own analysis and research, and only as these Terms allow. You must not:

1. scrape, crawl, bulk-download or harvest data from the Service by script, bot or other automated means;
2. resell, redistribute, publish or sublicense market data, analysis results or other content from the Service, or use it to build a competing product or dataset. An occasional screenshot of your own results for non-commercial discussion is fine, as long as you do not republish the underlying price data;
3. decompile or reverse engineer the Service, or try to extract its source code or algorithms, except where the law allows it;
4. get around plan limits, usage allowances, access controls or security measures, for example by creating several accounts to get more free runs or altering requests to reach data outside your plan;
5. share your account or let anyone else use your subscription;
6. disrupt or overload the Service, probe our systems for weaknesses without our written permission, or introduce harmful code;
7. use the Service in a way that breaks any law or regulation, including the rules of any exchange or market data provider;
8. use the Service to mislead others, for example by presenting hypothetical backtest results as actual trading results or as a guarantee of performance.

6. Content and ownership

Our intellectual property

The Service, including its software, design, text, logos, the SeasonalQuant name and our analytical methods, belongs to us or our licensors. Subject to these Terms and your plan, we give you a limited, personal, non-transferable, revocable licence to use the Service for your own analysis while your account is active. We keep all rights not expressly granted.

Your configurations and inputs

You keep any rights in the inputs you enter and the configurations you save, such as table layouts, filters, spreads and trade parameters, and you let us store and process them to run the Service for you. Saved configurations may be deleted when your account is closed, and may become unavailable on a plan that does not include them. If you send us feedback, we may use it freely.

7. Risk disclosure and no advice

Please read this section carefully.

• Analytics only. SeasonalQuant provides analytical software and historical data. Nothing in the Service, including screener results, seasonal patterns, backtests, optimizer output, forecasts and Monte Carlo simulations, is investment, trading, financial, tax or legal advice, or a recommendation or offer to buy or sell any futures contract or other financial instrument.
• Results are hypothetical. Backtests, historical performance figures and simulations are calculated after the fact from historical data and do not represent actual trading. They may not reflect commissions, fees, slippage, liquidity, margin, contract rolls or limit moves, and they benefit from hindsight. Forecasts and Monte Carlo outputs are statistical estimates based on assumptions and past data, not predictions.
• Past results do not guarantee future results. A seasonal pattern that held in the past may not hold in the future, as markets, weather, policy and contract specifications change.
• Futures trading is risky. Trading futures and futures spreads involves substantial risk of loss and is not suitable for everyone. Because futures are traded on margin, you can lose more than your initial deposit. Only trade with money you can afford to lose.
• No advisory or fiduciary relationship. We are not a broker, commodity trading advisor or investment adviser. Using the Service creates no advisory, fiduciary or client relationship. We do not know your financial situation, goals or risk tolerance, and nothing in the Service is tailored to you.
• Data may be wrong or late. Market data and calculations may contain errors, gaps or delays, and may not match prices at your broker or the exchange. Check important information independently before relying on it.
• Your decisions are your own. You alone are responsible for your trading decisions and their results. Consider advice from a qualified, independent professional.

8. Availability and changes to the Service

We do not promise that the Service will always be available or error-free. It may be unavailable during maintenance, updates, outages at our hosting or data providers, or for other reasons outside our control. We update price data regularly, but it may not be current at any given moment.

We may change, add or remove features, contracts, data coverage or plan contents. If a change substantially reduces the core features of a paid plan you have paid for, we will tell you in advance where we reasonably can, and you may cancel under Section 4.

9. Suspension and termination

You can stop using the Service at any time. To have your account deleted, email us from the address on your account at support@seasonal-quant.com. Cancel any paid subscription first, because deleting an account does not by itself issue a refund.

We may suspend or close your account, or limit your access to the Service, if:

1. you materially or repeatedly break these Terms, including the acceptable use rules in Section 5;
2. we reasonably believe your account is being used for fraud, abuse or unauthorized access, or poses a security risk;
3. a payment is not made or is reversed;
4. we are required to do so by law, a court or a regulator, or by our data providers; or
5. we stop offering the Service.

Where reasonable, we will tell you first and give you a chance to fix the problem. If we close your account through no fault of yours, or because we stop offering the Service, we will refund prepaid fees for the period after closure. If we close it because you broke these Terms, no refund is due. Sections 5 to 7 and 10 to 13 survive termination.

10. Disclaimer of warranties

To the fullest extent the law allows, the Service, including all data, analyses and content, is provided "as is" and "as available", without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, timeliness and non-infringement. We do not warrant that any data or result is correct, or that using the Service will lead to any trading profit. Where local law does not allow these exclusions, they apply only as far as it allows.

11. Limitation of liability

To the fullest extent the law allows:

1. we are not liable for any trading or investment losses, lost profits, lost revenue, lost data, loss of opportunity, or indirect, incidental, special, consequential or punitive damages arising from or related to the Service, even if we were told they were possible;
2. we are not liable for any decision you make, or any action you take or do not take, based on data, analyses or results from the Service;
3. our total liability for all claims relating to the Service or these Terms is limited to the greater of (i) the amount you paid us for the Service in the 12 months before the event that gave rise to the claim, and (ii) 100 US dollars.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, such as liability for fraud, for death or personal injury caused by negligence, or under mandatory consumer protection laws.

12. Indemnification

To the extent the law allows, you agree to defend and compensate us and our service providers for claims, losses and reasonable costs (including legal fees) arising from your breach of these Terms, your misuse of the Service or its data, or your violation of any law or anyone's rights. This does not apply to the extent a claim is caused by our own breach or negligence, and for consumers it applies only as far as local consumer law allows.

13. Governing law and disputes

These Terms, and any dispute arising from or relating to them or the Service, are governed by the laws of the country in which the operator of SeasonalQuant is established, without regard to its conflict-of-laws rules, and the courts of that country have jurisdiction, unless the law where you live gives you the right to bring a claim in your local courts.

If you are a consumer, you keep the protection of any mandatory laws of the country where you live, and nothing in this section takes that protection away.

Before starting formal proceedings, please contact us at support@seasonal-quant.com so we can try in good faith to resolve the issue informally within 30 days.

14. Changes to these terms

We may update these Terms when the Service, our providers or the law change. When we do, we will change the "Last updated" date at the top of this page. If a change is significant, for example to billing, cancellation or your rights, we will also tell you by email or in the app before it takes effect. If you keep using the Service after that, you accept the updated Terms. If you do not agree, stop using the Service and cancel any paid subscription. If any part of these Terms is unenforceable, the rest stays in effect.
