Terms of Service

The agreement between you and Cerci Ventures GmbH for the use of Tailwind Trader.

Version 1 Oct 2026

In short: a 7-day free trial, started with a payment method on file and free of charge · unless you cancel during the trial, it continues as the monthly or annual subscription you chose, which you can cancel online · EU and UK consumers have a 14-day right of withdrawal (section 7) · the scores are information, not investment advice (section 2).

1. Who you are contracting with

Tailwind Trader (“the Service”) is provided by Cerci Ventures GmbH, Marthashof 10, 10435 Berlin, Germany, commercial register Amtsgericht Charlottenburg HRB 151744 B (“we”, “us”; see the imprint). You can reach us at support@tailwindtrader.com or through the contact form.

These terms apply when you create an account, start the free trial or use the Windows application or the browser version. The contract language is English. You can view, save and print these terms at any time on this page; the version you accepted is also e-mailed to you when you subscribe.

2. What the Service is — and what it is not

The Service reads publicly published news headlines about a stock ticker, has them described as distinct events by an AI model, and applies your own event weights to produce one score per trading day. It adds values calculated from market data — relative strength, relative volume and sector strength — and shows the original headline, its publisher, its time and a link to the original article.

This is not investment advice. A score is the arithmetic result of rules you set, applied to news that other people published. It is not a recommendation to buy, sell or hold anything, not a forecast, and not a statement that the news is true or complete. We do not know your financial situation and do not assess whether anything is suitable for you. We are not an investment firm, not a financial adviser and not a rating agency. Every trading decision is yours alone, and trading carries the risk of losing money.

The AI part, stated plainly: the event descriptions and one-line summaries you see are generated by an AI model and are not reviewed by a human before you see them. They can be wrong, incomplete, or can misread what an article meant. The original headline and the link to the source are shown next to every event precisely so that you can check.

3. Your account

You must be at least 18 years old and legally able to enter into a contract. You are responsible for keeping your sign-in details and your access keys to yourself. One account is for one person; it may not be shared, resold or used by several people. We may suspend an account that is being shared, and will tell you why.

4. The free trial

You get a free trial of 7 days with all features. You start it on your account page once you have confirmed your e-mail address: you choose the monthly or the annual plan and give a payment method at the checkout (section 5). Nothing is charged for the trial.

The subscription begins with the trial. Unless you cancel before the trial ends, it continues as the plan you chose, and its price is charged on the day the trial ends. You receive a reminder by e-mail before that day.
If you cancel during the trial (section 6), the subscription ends when the trial ends and nothing is charged.
One trial per person and per payment card. If an address, a person or a card has already had a trial, the subscription starts without a trial, or a trial that was started anyway is ended at once without charge; we tell you by e-mail.

5. Subscriptions, prices and payment

Pro, monthly: USD 49 per month.
Pro, annual: USD 468 per year, paid in advance (USD 39 per month).

Taxes: for customers in the European Union, the EEA and the United Kingdom the prices above include VAT. In the United States and other countries, sales tax or similar taxes are added where they apply. The checkout page shows the total price including tax before you pay, and nothing is charged that was not shown there.

Who sells the subscription to you. The checkout page names the seller, and that decides which of the following applies:

A reseller (“merchant of record”). We may offer the subscription through a payment company that buys access to the Service from us and resells it to you — for example Paddle.com Market Ltd. In that case your purchase contract, the payment, the tax, the invoice, refunds and the statutory right of withdrawal are governed by the reseller’s buyer terms, which the checkout shows you. These terms govern your use of the Service. We also accept a withdrawal or cancellation that you send to us and pass it on without delay.
Us. If the checkout names Cerci Ventures GmbH as the seller, the contract is concluded with us when you click the final button of the checkout (“Subscribe and pay”); the payment service named there only processes the payment.

Accepted payment methods are those shown at checkout. The payment method you give when you start the trial is kept by the seller and charged when the trial ends and on each renewal. If a renewal payment fails, it may be retried over a few days and you are told by e-mail; if it still fails, your access ends at the end of the paid period and you can subscribe again at any time.

6. Term, renewal and cancellation

Monthly: the subscription renews automatically every month until you cancel. A cancellation takes effect at the end of the current month.
Annual: the subscription renews automatically for another twelve months at the end of each term, unless you cancel before the renewal date. We remind you by e-mail 15 to 45 days before an annual renewal, with the date and the price. A cancellation takes effect at the end of the current term.
Consumers resident in Germany: after the first twelve months your annual subscription continues for an indefinite period instead, and you can cancel it at any time with one month’s notice; any amount paid in advance for the time after the cancellation takes effect is refunded pro rata. Where the law of your country gives you further rights on renewal or cancellation, those apply as well.
You can cancel online on your account page with the button “Cancel contract here”, as well as by e-mail to support@tailwindtrader.com or in the reseller’s customer portal. You receive a confirmation by e-mail immediately, with the date your access ends. No reason is needed.
We may terminate a subscription with one month’s notice to the end of a billing period, and at any time for good cause, in particular a serious breach of these terms; we tell you the reason.

7. Right of withdrawal (consumers in the EU, the EEA and the UK)

If you are a consumer, you have the following statutory right of withdrawal. Where a reseller sells the subscription to you (section 5), the right is exercised towards the reseller under its buyer terms; a withdrawal sent to us reaches it too.

Right of withdrawal

You have the right to withdraw from this contract within 14 days without giving any reason. The withdrawal period will expire after 14 days from the day of the conclusion of the contract.

To exercise the right of withdrawal, you must inform us (Cerci Ventures GmbH, Marthashof 10, 10435 Berlin, Germany, e-mail support@tailwindtrader.com) of your decision to withdraw from this contract by an unequivocal statement (e.g. a letter sent by post or an e-mail). You may use the model withdrawal form below, but it is not obligatory. You can also exercise your right of withdrawal online with the button “Withdraw from contract” on your account page. If you use this online function, we will send you an acknowledgement of receipt on a durable medium (e.g. by e-mail) without delay, stating the content of your withdrawal and the date and time it was received.

To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal

If you withdraw from this contract, we shall reimburse to you all payments received from you without undue delay and in any event not later than 14 days from the day on which we are informed about your decision to withdraw from this contract. We will carry out such reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.

If you requested to begin the performance of services during the withdrawal period, you shall pay us an amount which is in proportion to what has been provided until you have communicated us your withdrawal from this contract, in comparison with the full coverage of the contract.

Widerrufsbelehrung (Deutsch)

Widerrufsrecht

Sie haben das Recht, binnen vierzehn Tagen ohne Angabe von Gründen diesen Vertrag zu widerrufen. Die Widerrufsfrist beträgt vierzehn Tage ab dem Tag des Vertragsabschlusses.

Um Ihr Widerrufsrecht auszuüben, müssen Sie uns (Cerci Ventures GmbH, Marthashof 10, 10435 Berlin, Deutschland, E-Mail: support@tailwindtrader.com) mittels einer eindeutigen Erklärung (z. B. ein mit der Post versandter Brief oder eine E-Mail) über Ihren Entschluss, diesen Vertrag zu widerrufen, informieren. Sie können dafür das beigefügte Muster-Widerrufsformular verwenden, das jedoch nicht vorgeschrieben ist. Sie können Ihr Widerrufsrecht auch online über die Schaltfläche „Vertrag widerrufen“ auf Ihrer Kontoseite ausüben. Wenn Sie diese Online-Funktion nutzen, übermitteln wir Ihnen auf einem dauerhaften Datenträger (z. B. durch eine E-Mail) unverzüglich eine Eingangsbestätigung mit Informationen zum Inhalt der Widerrufserklärung sowie dem Datum und der Uhrzeit ihres Eingangs.

Zur Wahrung der Widerrufsfrist reicht es aus, dass Sie die Mitteilung über die Ausübung des Widerrufsrechts vor Ablauf der Widerrufsfrist absenden.

Folgen des Widerrufs

Wenn Sie diesen Vertrag widerrufen, haben wir Ihnen alle Zahlungen, die wir von Ihnen erhalten haben, unverzüglich und spätestens binnen vierzehn Tagen ab dem Tag zurückzuzahlen, an dem die Mitteilung über Ihren Widerruf dieses Vertrags bei uns eingegangen ist. Für diese Rückzahlung verwenden wir dasselbe Zahlungsmittel, das Sie bei der ursprünglichen Transaktion eingesetzt haben, es sei denn, mit Ihnen wurde ausdrücklich etwas anderes vereinbart; in keinem Fall werden Ihnen wegen dieser Rückzahlung Entgelte berechnet.

Haben Sie verlangt, dass die Dienstleistungen während der Widerrufsfrist beginnen sollen, so haben Sie uns einen angemessenen Betrag zu zahlen, der dem Anteil der bis zu dem Zeitpunkt, zu dem Sie uns von der Ausübung des Widerrufsrechts hinsichtlich dieses Vertrags unterrichten, bereits erbrachten Dienstleistungen im Vergleich zum Gesamtumfang der im Vertrag vorgesehenen Dienstleistungen entspricht.

Muster-Widerrufsformular

Note: the contract is concluded when you start the trial (section 4), so the withdrawal period starts on that day. A withdrawal during the trial ends the trial at once; nothing has been charged, so there is nothing to pay and nothing to refund.

8. Price changes

A price change for a running subscription applies only if you agree to it. We ask you by e-mail at least 30 days before the change would take effect. If you do not agree, your subscription continues at the old price, and we may then terminate it with one month’s notice to the end of a billing period.

9. Changes to the Service

We develop the Service continuously. We may change it where there is a valid reason — in particular to adapt it to a new technical environment or more users, to replace a data source or an AI provider that changes its terms or stops serving us, to meet legal requirements, or for security — provided the change costs you nothing extra. We tell you clearly and in time. If a change more than slightly impairs your access to or use of the Service, we tell you at least 30 days in advance, and you may end the contract free of charge within 30 days of the change or of our notice, whichever is later.

10. Fair use

“Unlimited lookups” means unlimited normal use by one person. It does not cover automated querying, scripted bulk lookups, running the Service on behalf of others, or any use that puts a disproportionate load on our systems or on our data sources. If usage looks automated, we contact you first; if it continues, we may throttle or suspend the account.

11. Content, and what you may do with it

The headlines, publisher names and links shown in the Service belong to the publishers who wrote them. The summaries, the event structure and the scores are ours. You may use all of it for your own trading decisions and quote from it occasionally with attribution. You may not systematically copy, republish, redistribute or resell it, feed it into another product or public feed, or scrape it.

Your rules and your watchlist are yours. When the contract ends, you can ask us within 90 days for a copy in a common format, free of charge.

12. Availability

We aim to keep the Service available and current, but we do not promise a particular uptime and do not guarantee that news arrives completely or on time. The Service depends on outside news sources, market-data providers and an AI provider; if one of them fails, changes its terms or stops serving us, parts of the Service may be delayed, degraded or replaced (section 9).

13. Liability

We are liable without limitation for damage caused intentionally or by gross negligence, for injury to life, body or health, under a guarantee we gave, and where liability is mandatory by law (including the German Product Liability Act). For slight negligence we are liable only for breach of an obligation that is essential to performing this contract at all and on whose fulfilment you may regularly rely, and then only for the foreseeable damage typical of this kind of contract. All other liability is excluded. Your statutory rights for a defective digital service remain unaffected.

In particular, we are not liable for trading losses, missed opportunities, or decisions made on the basis of a score, a summary, a calculated value or a missing piece of news (section 2).

14. Transfer of the contract

From 1 January 2027 the Service is to be provided by CK Marketing & Services GmbH, Berlin (also under any later name of that company). We may transfer this contract with all rights and obligations to that company. We tell you by e-mail at least four weeks in advance; if you do not want the transfer, you can cancel free of charge with effect from the date of the transfer. Nothing else about your subscription changes.

15. Governing law and disputes

These terms are governed by German law, excluding the UN Convention on Contracts for the International Sale of Goods. If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country in which you live. If you are a merchant, the courts of Berlin have jurisdiction; consumers can be sued only in the courts of the place where they live.

If you live in the United States, nothing in these terms limits a right under the law of your state that cannot be waived by contract. We are neither willing nor obliged to take part in dispute resolution proceedings before a consumer arbitration board.

16. Third-party names and marks

“S&P 500” is a registered trademark of S&P Dow Jones Indices LLC; “Nasdaq-100” is a registered trademark of Nasdaq, Inc. Both names appear in the Service only to describe which companies the morning briefing covers. Tailwind Trader is not sponsored, endorsed, sold or promoted by S&P Dow Jones Indices, Nasdaq or any index provider, and none of them makes any representation about the Service. The names of sector and theme funds are used only to describe what a sector value is calculated against. The publishers named next to headlines own those headlines; their names identify the source and imply no relationship with us. TradingView and other charting platforms the application can read a ticker from are trademarks of their owners; the Service is not affiliated with them.

17. Publishers

If you are a publisher and do not want your content processed or displayed by the Service, see the notice for publishers. We act on such requests.

18. Changes to these terms, and if part of them is invalid

Changes to these terms for a running subscription need your agreement, as in section 8. If a provision of these terms turns out to be invalid, the rest stays in force.
