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 (Trader, Pro, Elite, or 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, Playbook Audit) 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.

§ 3 Registration, conclusion of contract

(1) During the beta phase, registration is invite-only. The user redeems an invite code issued by the Provider and sets a password.

(2) By submitting the registration form, the user makes a binding offer to enter into a usage contract. The Provider accepts the offer by creating the account and sending a confirmation email (welcome email).

(3) The contract text is stored by the Provider. The user can access contract data and invoices at any time through the Stripe Customer Portal and the in-app data export.

(4) 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, payment

(1) The Application is offered in the plans Trader, Pro, Elite, and Founder Lifetime. 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. Subsequent periods auto-renew; payment is collected via the stored payment method (credit card or SEPA Direct Debit).

(3) The Founder Lifetime plan 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. Founder Lifetime is capped at 100 seats; once exhausted, it is no longer available. Payment for this plan is by credit card only (see § 4(4)).

(4) Payment is processed via Stripe Payments Europe Ltd. SEPA Direct Debit is supported for monthly and annual subscriptions but not for Founder Lifetime (rationale: the 8-week SEPA reversal window does not fit a one-time lifetime grant). On repeated failed collection, the Provider grants a seven-day grace period; if it expires unpaid, the account moves to a read-only state until billing is resolved.

(5) 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. The Founder Lifetime price is fixed at purchase and not subject to subsequent price adjustments.

§ 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, 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, ordinary termination

(1) The user can upgrade, downgrade, or cancel the subscription at any time via the Stripe Customer Portal.

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

(3) After cancellation 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.

(4) 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

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.

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). 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.

Early expiry of the right of withdrawal. For a contract for the supply of digital content not on a tangible medium, the right of withdrawal expires if we have begun performance of the contract after you have given express consent to performance commencing before the withdrawal period has expired and you have acknowledged that you will lose your right of withdrawal as a result of your consent (§ 356(5) BGB). Active use of the Application within the withdrawal period constitutes such consent.

§ 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, all personal data, trades, setups, rules, AI reviews, morning briefs, and trading accounts are irrevocably deleted. Any active Stripe subscription is cancelled at the same time.

(3) A complete data export is available at any time under Settings → Data export as a ZIP archive (Art. 20 GDPR).

§ 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 European Commission provides a platform for online dispute resolution (ODR) accessible at https://ec.europa.eu/consumers/odr/. The Provider is neither willing nor obliged to participate in dispute resolution proceedings before a consumer arbitration body.
