Draft of 2026-10-10, awaiting legal review. Words in square brackets are still to be filled in.
SeasonalEdge (the “Service”), at seasonaledge.com, is operated by SeasonalEdge.com (“we”, “us”). These terms are an agreement between you and us. By creating an account or using the Service you accept them, together with the privacy policy and the notice on hypothetical performance on this page.
The Service is research software. It measures how US stocks and ETFs behaved around recurring calendar dates in the past, and shows those measurements as hypothetical, simulated results.
The Service is not investment advice, a recommendation, or an offer to buy or sell any security. We are not a broker, an investment adviser or a portfolio manager. We do not know your finances, goals or tolerance for risk, and we place no orders. Every decision to trade, and its result, is yours alone.
Nothing in the Service is a forecast. Calendar patterns can weaken or stop, and several already have. Read the notice on hypothetical performance before you rely on any figure.
You must be at least 18 years old and able to form a binding contract to create an account.
An account is for one person. Give an email address you control, keep your password to yourself, and tell us at admin@seasonaledge.com if you think someone else has used your account. You are responsible for what is done through it.
We use your email address to confirm the account, to reset your password, and to tell you about your account, these terms and changes to the Service.
Parts of the Service may require a paid membership. Until membership opens, no payment is taken. When it opens:
The Service is for your own research. You agree not to:
Prices come from third-party data providers. They can be late, incomplete or wrong, and we do not guarantee them. The providers keep their rights in their data, which is one reason the Service is for your own use only.
Exports, such as code for a trading platform, are built from the same hypothetical figures. Check an export yourself before you use it, and try it on a simulated account first.
The Service, its software, design, text and the figures it computes belong to us or our licensors. We give you a personal, non-exclusive, non-transferable licence to use the Service under these terms, which ends when your account ends.
You can stop using the Service at any time, and ask us to delete your account from your account page.
We may put your account on hold or close it if you break these terms, if a payment fails, or if the law requires it. Where it is reasonable, we tell you why.
We may change or remove features. If we close the whole Service, we refund the unused part of any period you paid for.
The Service is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim every warranty, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We do not promise that the Service will be uninterrupted, timely or free of errors.
To the fullest extent the law allows, we are not liable for any trading or investment loss, lost profit, or indirect, incidental, special or consequential damage that comes from using the Service or relying on its figures.
Our total liability for all claims about the Service is limited to the greater of what you paid us in the 12 months before the claim and [LIABILITY FLOOR].
Some places do not allow these limits. There, they apply only as far as the law allows. Nothing in these terms limits a liability that the law does not allow to be limited.
You agree to cover our reasonable losses, including legal fees, from a claim by someone else that results from your breaking these terms or misusing the Service.
We may update these terms. We will tell you about a material change by email or in the Service at least [NOTICE PERIOD] days before it takes effect. If you keep using the Service after that, the new terms apply; if you do not accept them, cancel and stop using the Service.
These terms are governed by the laws of [GOVERNING LAW], without regard to its rules on conflicts of law. Disputes go to the courts of [VENUE], unless the law of the country where you live gives you the right to bring a claim there.
These terms, the privacy policy and the notice on hypothetical performance are the whole agreement between you and us about the Service. If a part of them cannot be enforced, the rest still applies. Not enforcing a right is not giving it up. We may transfer these terms to a company that takes over the Service; you may not transfer them.

SeasonalEdge.com (“we”) is responsible for the personal data processed through SeasonalEdge. Write to admin@seasonaledge.com about anything in this policy.
The research pages you open are answered by our servers and are not stored against your account; Google Analytics, if you allow it, counts which pages are opened without linking them to your account. What you follow, your recent symbols, your theme and your table settings stay in your browser’s local storage and are not sent to us.
We do not ask for sensitive data, such as health or political opinions, and we do not knowingly collect data from anyone under 18.
We do not sell or rent personal data, we do not share it for advertising, and we make no automated decision about you that has a legal or similarly significant effect.
These providers process personal data for us, under contracts that limit them to our instructions:
We also disclose data when the law requires it, to protect our rights or someone’s safety, or to a company that takes over the Service, which must then honour this policy.
Our providers may process data outside the country where you live, including in the United States. Where the law requires it, these transfers rely on safeguards such as the EU’s standard contractual clauses or the EU-US Data Privacy Framework.
Depending on where you live, you can ask to see the personal data we hold about you, correct it, delete it, receive a copy of it, restrict or object to how we use it, and withdraw a consent you gave. Write to admin@seasonaledge.com from your account’s email address; we answer within one month, or sooner where your law says so. You can also ask for your account to be deleted from your account page.
If you live in the European Economic Area, the United Kingdom or Israel, you can also complain to your data protection authority; in Israel, that is the Privacy Protection Authority.
If you live in California or another US state with a privacy law: we do not sell or share personal information as those laws define it, and we will not treat you differently for using your rights.
We set one cookie of our own: your session, after you sign in (better-auth.session_token, or __Secure-better-auth.session_token on the secure site). It is needed for signing in and ends with your session. If you accept analytics cookies, Google Analytics sets its own cookies (_ga and _ga_ followed by an identifier), which keep a random identifier for up to two years. Where your consent is required, they are not set until you accept; until then Google Analytics receives only cookieless pings with no identifier. We use no advertising cookies. You can change your choice at any time with Cookie settings at the bottom of every page.
Your browser’s local storage keeps your settings: theme, table columns, your round-trip cost, what you follow, your recent symbols and your cookie choice. They are not sent to us; clearing the site’s data in your browser removes them.
Passwords are stored as salted hashes, every connection uses HTTPS, sign-in tokens expire after 15 minutes, and only the operator can reach production data. No system is perfectly secure; if a breach affects your data, we will tell you and the authorities where the law requires it.
We will post any change to this policy here and email you before a material change takes effect. Questions and requests: admin@seasonaledge.com, or SeasonalEdge.com, [POSTAL ADDRESS].
Every return, hit rate, equity curve, excess and other figure in SeasonalEdge is hypothetical. It shows what would have happened if a rule had been followed in the past, computed from historical prices. No account traded it, and no money was made or lost.
No representation is made that any account will or is likely to achieve profits or losses similar to those shown. There are frequently sharp differences between hypothetical results and the results later achieved by actual trading.
Every return is gross: it leaves out broker fees, taxes, the gap between buying and selling prices, and every other cost of trading. The Service shows a break-even cost beside each rule. If a round trip costs you more than this, the average trade loses money.
Rules are found on prices up to the research cutoff. What they did after it, shown as the Track Record, is computed the same way and is just as hypothetical: no account traded it either.
Trading stocks and ETFs can lose you money, and trading on margin or with leverage can lose you more than you put in. Trade only with money you can afford to lose, and consider advice from a licensed professional who knows your situation.
