Terms of Service

These Terms of Service ("Terms") govern the contract between Core Structure Trading - Thomas Seifert, Silberweidenweg 10, 10365 Berlin (the "Provider") and the user of the SaaS application "Tradelyst" advertised at https://tradelyst.ai and provided at https://app.tradelyst.ai (the "Application" or "Service"). The version applicable is the one in force at the time of conclusion of the contract.

This is a courtesy translation of the German "Allgemeine Geschäftsbedingungen". In case of any discrepancy, the German original prevails. German law remains the governing law (see § 15).

§ 1 Scope, definitions

(1) These Terms apply to all contracts between Provider and user regarding the use of the Application. Conflicting or supplementary terms of the user shall not become part of the contract unless the Provider expressly agrees to them in writing.

(2) User means both consumers (§ 13 BGB) and businesses (§ 14 BGB). Where a clause applies exclusively to one group, this is noted.

(3) Plan refers to the paid tier the user subscribes to (Trader or Pro, and for existing contracts Elite and Founder Lifetime).

§ 2 Subject matter, scope of services

(1) The Provider grants the user use of the Application as a digital trading journal for self-reflection on already-executed futures trades. The functional scope and limits follow from the selected Plan; the current feature matrix is on the pricing page.

(2) The Application is expressly not a financial instrument, not a securities or investment service within the meaning of the German WpHG, not investment advice, not investment broking, not financial analysis, and not a recommendation to buy or sell any financial instrument. All statistics, analyses, and AI-generated content (e.g. Morning Brief, Post-Trade Review, Daily Review) serve exclusively for retrospective self-reflection on trade data the user enters or imports themselves.

(3) The Provider owes no particular performance, return expectation, or success ratio in relation to the user's trades. Trading carries significant risk of loss up to total loss of capital deployed.

(4) At the user's request, the Application can connect an account at the broker Tradovate via its OAuth interface to import trades automatically. Tradovate is an independent third party; the availability and scope of the data it provides are outside the Provider's control. The Application does not place orders.

§ 3 Registration, conclusion of contract

(1) The user registers via the registration form with their email address and a password, accepting these Terms in doing so. In special cases (such as partner or community campaigns) the Provider issues invite codes with which the user creates the account; such a code may grant a plan free of charge for a period stated with the code.

(2) By submitting the registration form, the user makes a binding offer to enter into a usage contract for the free tier. The Provider accepts the offer by creating the account; the user then receives an email with a link to confirm their email address.

(3) The user takes out a paid subscription in the Application under Settings → Billing: they choose plan and billing interval, give the confirmation under § 8(3) and complete the order on Stripe's payment page. The contract is concluded when that order is completed.

(4) The contract text is stored by the Provider. After taking out a subscription the user receives a contract confirmation by email with the contract's content and these Terms and the cancellation policy attached. The user can access contract data and invoices at any time through the Stripe customer portal and the in-app data export.

(5) The user warrants that the data provided on registration is truthful and complete and that they are at least 18 years old.

§ 4 Plans, prices, free trial, payment

(1) The Application is offered in the free plan Free and in the paid plans Trader and Pro. The Elite plan is currently not offered; existing Elite contracts continue at the price agreed at purchase, subject to price changes under § 4(6). Current prices and feature scopes are shown on the pricing page. All prices stated there include statutory VAT; B2B customers receive an invoice with a reverse-charge note where a VAT ID is on file and the applicable VAT regime requires it.

(2) Billing is — depending on the user's choice — monthly or annual in advance, first on the day of contract conclusion or, for a subscription taken out during a free trial, at the end of the trial, unless para. 3 provides otherwise. Payment is collected via the stored payment method (credit card or SEPA Direct Debit). For the term and automatic renewal see § 7(3).

(3) Free trial. New users receive, on confirming their email address — with an invite code bound to their email address already on registration; with an invite code that grants a plan, that plan applies instead — a free trial if, and for as long as, one is offered on the pricing page (currently 14 days). During the trial the account limit and features of the Pro plan apply, with two restrictions for as long as the user has not taken out a subscription: AI-written text is subject to the Trader plan's AI budget, and missing chart data is fetched only for the contracts stored by default (NQ, ES and GC and their micro contracts MNQ, MES, MGC). No payment method is required for the trial. The trial ends automatically; the account then continues on the free plan, at no cost and without any cancellation. If the user takes out a subscription during the trial, its billing starts when the trial ends (para. 2); if they take it out in the last 48 hours of the trial, billing starts on the day it is taken out, because the payment provider Stripe only allows a later billing start with at least 48 hours' notice. A trial is granted only once per user and per mailbox; variants of the same address (for example with a "+tag" or, for Gmail, with dots) count as the same mailbox.

(4) Founder Lifetime. The Founder Lifetime plan is currently not offered. For existing Founder Lifetime contracts: it is a one-time payment in exchange for lifetime use of the Pro/Elite features available at purchase plus all later extensions that form part of the technical scope of the Application; the price is fixed at purchase and not subject to subsequent price adjustments.

(5) Payment is processed via Stripe Payments Europe Ltd. SEPA Direct Debit is supported for monthly and annual subscriptions. If collection fails, the Provider grants a seven-day grace period; if it expires unpaid, the account may be moved to a read-only state until billing is resolved.

(6) If the Provider changes the prices on the pricing page, this applies only to subscriptions taken out afterwards; it does not change the price of running subscriptions. Price changes for ongoing subscriptions are announced by email at least 30 days before they take effect. In the event of a price increase, the user has the right to terminate the subscription extraordinarily with effect from the date of the increase.

§ 5 Beta phase, availability, maintenance

(1) The Application is under active development at the start of the beta programme. Features may change, be added, or in individual cases be removed, provided the contractual core purpose (trade journal) is not materially impaired.

(2) No specific minimum availability is guaranteed. The Provider aims for monthly availability of at least 99 % (outside planned maintenance windows and third-party outages). Planned maintenance is generally performed outside US market hours and announced in-app.

(3) Outages of integrated third-party services (in particular Stripe, OpenAI, Databento, Resend, Tradovate, hosting) do not in themselves give rise to claims for damages or fee reduction, provided the Application itself remains substantially functional.

§ 6 User obligations

(1) The user is obliged to:

  • keep their credentials secret and protect them against unauthorised access,
  • immediately report any suspected compromise and use "Sign out everywhere" or change the password,
  • not use the Application in any way that impairs its security, integrity, or availability (in particular no reverse engineering, no mass scraping, no automated account creation),
  • not upload or input content that violates applicable law or third-party rights,
  • take responsibility for the substantive accuracy of any trade data they enter or import.

(2) The Provider may suspend the account after a warning, or terminate the contract for cause, in case of sustained or material breach of these obligations.

§ 7 Plan changes, term, termination

(1) The user can change their plan in the Application under Settings → Billing.

(2) Upgrades take effect immediately; the difference is billed pro rata. Downgrades take effect at the end of the current billing period; amounts already paid for the running period are not refunded.

(3) A monthly subscription runs for one month, an annual subscription for one year. The subscription renews automatically for a further month or a further year respectively unless it is terminated before the end of the current billing period. The user can terminate the subscription at any time with effect from the end of the current billing period; amounts already paid for the current period are not refunded pro rata unless mandatory statutory provisions provide otherwise.

(4) Termination can be declared via the "Cancel contracts here" page (reachable without logging in), via the Stripe customer portal (Settings → Billing), or by email to support@tradelyst.ai. Both parties' right to terminate extraordinarily for good cause remains unaffected.

(5) After a termination takes effect, the account is moved to the free tier. All trade data is preserved and remains accessible — including via the data export — but certain features (e.g. AI Coach, additional trading accounts) are reduced. The account itself is only deleted if the user deletes it under § 10.

(6) The Founder Lifetime plan cannot be cancelled as a subscription since there is no recurring payment. The user can delete their account under § 10 at any time.

§ 8 Right of withdrawal for consumers

(1) Consumers have the following right of withdrawal. A consumer is any natural person entering into a legal transaction for purposes that can predominantly be attributed neither to their commercial nor to their independent professional activity.

(2) Withdrawal notice

Right of withdrawal. You have the right to withdraw from this contract within fourteen days without giving any reason. The withdrawal period is fourteen days from the day of conclusion of the contract. To exercise your right of withdrawal you must inform us (Core Structure Trading - Thomas Seifert, Silberweidenweg 10, 10365 Berlin, email: contact@tradelyst.ai) of your decision to withdraw from this contract by a clear statement (e.g. a letter sent by post or an email). You may use the attached model withdrawal form, but it is not obligatory. To meet the withdrawal deadline it is sufficient that you send the communication concerning the exercise of the right of withdrawal before the withdrawal period has expired.

Effects of withdrawal. If you withdraw from this contract we will reimburse to you all payments received from you, including the costs of delivery (with the exception of supplementary costs resulting from your choice of a type of delivery other than the least expensive type of standard delivery offered by us), without undue delay and not later than fourteen days from the day on which we are informed of 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 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 to us your withdrawal from this contract, in comparison with the full coverage of the contract.

Early expiry of the right of withdrawal. For a contract for the supply of services, the right of withdrawal expires once we have fully performed the service, if we began performance only after you gave your express consent to that and at the same time acknowledged that you lose your right of withdrawal once we have fully performed the contract (§ 356(4) BGB). Insofar as the contract concerns the supply of digital content not on a tangible medium, the right of withdrawal expires once we have begun performance after you have expressly consented to our beginning performance before the withdrawal period expires, you have acknowledged that your consent means you lose your right of withdrawal once performance begins, and we have provided you with a confirmation of the contract on a durable medium (§ 356(5) BGB).

— End of withdrawal notice —

(3) How consent is obtained. Before a paid subscription is taken out (including one with a free trial) and before a plan change, the billing page shows a separate checkbox, not ticked by default, with the following statement: "I expressly request that Tradelyst begins performing the contract before the withdrawal period ends. I acknowledge that I thereby lose my right of withdrawal: for digital content as soon as performance begins, otherwise once the contract has been fully performed. If I withdraw before then, I pay a proportionate amount for the service provided up to that point." The order can only be started once the box is ticked. The Provider stores the time and the text version of the confirmation. Merely using the Application does not constitute consent.

(4) Model withdrawal form

(Complete and return this form only if you wish to withdraw from the contract.)

  • To Core Structure Trading - Thomas Seifert, Silberweidenweg 10, 10365 Berlin, Germany, email: contact@tradelyst.ai:
  • I/We (*) hereby give notice that I/We (*) withdraw from my/our (*) contract of sale of the following goods (*)/for the provision of the following service (*),
  • Ordered on (*)/received on (*),
  • Name of consumer(s),
  • Address of consumer(s),
  • Signature of consumer(s) (only if this form is notified on paper),
  • Date

(*) Delete as appropriate.

§ 9 Licence, intellectual property

(1) The Provider grants the user, for the term of the contract, a non-exclusive, non-transferable right to use the Application within the contractual scope.

(2) All rights in the Application, the source code, content, designs, trade marks, and text remain with the Provider or its licensors.

(3) Content entered or imported by the user (trades, setups, rules, notes, screenshots) remains the user's property. The user grants the Provider a non-exclusive, worldwide, royalty-free right to process this content solely for the purpose of providing the Application — in particular for in-account display, statistics computation, AI processing (if enabled), and data backup. This licence ends with deletion of the account.

§ 10 Account deletion, data export

(1) The user can delete their account at any time under Settings → Account → Danger zone. Once triggered, the account enters a 30-day pre-delete state during which the user can reverse the deletion or export their data.

(2) After the 30 days elapse, the Provider first cancels all of the user's running Stripe subscriptions. Then all personal data, trades, setups, rules, notes, screenshots, AI reviews, morning briefs, daily reviews, trading accounts and broker connections are irrevocably deleted, unless statutory retention or evidentiary obligations prevent this (see the Privacy Policy, Section 13).

(3) Under Settings → Account & data export the user can download a data export as a ZIP archive at any time (Art. 20 GDPR); its scope is described in the Privacy Policy, Section 14. The Provider supplies further data on request.

§ 11 Risk warning

Trading futures, foreign exchange, and other financial instruments involves significant risk of loss up to total loss of capital deployed. Past performance and statistics in the trade journal are no guarantee of future results. The Application does not replace your own research, risk assessment, or advice from a regulated entity. You make your investment decisions exclusively at your own responsibility.

§ 12 Liability

(1) The Provider is liable without limitation for intent and gross negligence, for injury to life, limb, or health, under the German Product Liability Act, and within the scope of a guarantee assumed by the Provider.

(2) For slight negligence in the breach of material contractual obligations (cardinal duties), the Provider's liability is limited in amount to foreseeable damage typical for the contract. Material contractual obligations are those whose fulfilment makes the proper performance of the contract possible in the first place and on whose observance the user can regularly rely.

(3) Beyond this, the Provider is not liable. In particular, the Provider is not liable for lost profits, trading losses, consequential damages, or indirect damages suffered by the user as a result of content displayed in the Application or AI-generated text. This does not apply in cases of § 12(1).

(4) Insofar as the Provider's liability is excluded or limited, this also applies to the personal liability of its employees, representatives, and vicarious agents.

§ 13 Data protection

Details on the processing of personal data are set out in our Privacy Policy.

§ 14 Changes to these Terms

(1) The Provider reserves the right to adapt these Terms where necessary due to changes in the law, supreme-court rulings, technical developments, or to close regulatory gaps, and where the adaptation does not unreasonably disadvantage the user.

(2) Planned changes are communicated to the user by email at least 30 days before they take effect. If the user does not object to the change within this period in writing or by email, consent is deemed granted. The Provider will separately point out the right of objection in the change notice. If the user objects, the Provider is entitled to terminate the contract ordinarily as of the date the change would have taken effect.

§ 15 Final provisions

(1) The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods. As against consumers, this choice of law applies only insofar as the protection of mandatory provisions of the law of the state of the consumer's habitual residence under Art. 6(2) Rome I Regulation is not withdrawn.

(2) The place of jurisdiction for all disputes arising from or in connection with this contract is — provided the user is a merchant, a legal person under public law, or a special fund under public law — Berlin. For consumers, the statutory venues apply.

(3) Should any provision of these Terms be or become invalid in whole or in part, the validity of the remaining provisions shall remain unaffected. In place of the invalid provision, the legally permissible regulation that comes closest economically to the purpose of the invalid provision shall apply.

(4) The Provider is neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration body (§ 36 VSBG).
