Terms of Service

1. Scope

These Terms of Service ("Terms") govern the use of the partiqon software-as-a-service platform ("partiqon" or "the Platform"), operated by Hendrik Hangmann, Leopoldstr. 2-8, 32051 Herford, Germany, phone +49 155 11556245, email support@partiqon.com ("Provider"), by registered users ("User").

Any terms and conditions of the User that deviate from, conflict with, or supplement these Terms do not become part of the contract unless the Provider expressly agrees to their applicability in writing.

2. Description of services

partiqon is a web-based tool for developing, backtesting, and optimizing algorithmic trading strategies based on historical price data provided by the user ("Bring Your Own Data"). The specific scope of features depends on the pricing tier booked (Free, Pro, Premium) as set out in the current description of services on the website.

partiqon is explicitly not a financial services provider, broker, signal provider, or investment advisor. The Platform does not execute orders, has no connection to brokerage accounts, and does not issue buy or sell recommendations. Further details are set out in sections 8 to 8b of these Terms.

The Provider strives to ensure high availability of the Platform but does not guarantee uninterrupted availability, particularly during maintenance, technical disruptions, or force majeure.

3. Registration and access

Access to partiqon is currently invite-only, via a waitlist. There is no entitlement to being granted access or to being added to the waitlist.

Registration requires truthful provision of the requested information. The User is obligated to keep their access credentials confidential and to inform the Provider immediately if there is reason to believe that unauthorized third parties have gained knowledge of the credentials.

4a. Retention of uploaded datasets

Datasets uploaded by the User (in particular historical price data) are stored for as long as they are used. If a dataset has not been used in any backtest for 90 days, the Provider notifies the User by email, at the address stored in the account, that the dataset will be deleted. Deletion takes place no earlier than 14 days after this notification has been delivered.

If the dataset is used in a backtest before that period ends, it is not deleted and the 90-day period starts again. The User may download the dataset at any time until it is deleted. No dataset is deleted without a delivered notification.

Only the uploaded dataset files are affected. Strategies, graphs, configurations and backtest results created by the User remain untouched by this rule; how many results are kept is set out in section 4b.

4b. Saved results and exports

The history of a strategy keeps its newest 50 results (backtests, walk-forward runs, walk-forward optimisations and optimisations together). When a new result is saved, the oldest one beyond that number is deleted.

The raw-data export of an optimisation keeps its newest 3 archives. When a new export is finished, the oldest one beyond that number is deleted.

Both limits apply to every account and plan. The history is a record of recent runs, not an archive; the User downloads an export archive the User wants to keep for longer. The application states both numbers where the history and the export are shown.

5. Prices, payment and plan changes

The prices of the paid plans (Pro, Premium) are those shown in the pricing overview on the website and in the account when the plan is booked. Paid plans are billed in advance, monthly or annually, according to the billing interval chosen.

Payment is processed by the payment service provider Stripe Payments Europe, Limited, Dublin, Ireland, through its payment form in the plan dialog of the account. The accepted means of payment are credit and debit cards, also through Apple Pay or Google Pay. The User places the order in that dialog with the button that states the obligation to pay; the contract for the paid plan is concluded, and the subscription starts, when the first payment has been made.

If a payment fails, Stripe retries it automatically. The User is informed by email of every failed attempt and keeps the paid plan until the date stated in that email, which is at least three days after the first failed payment. If no payment has been made by then, the account is moved to the Free plan; a later successful payment restores the paid plan. Data and strategies are kept in either case.

The User may switch to another paid plan or billing interval at any time in the account, with the button that states the obligation to pay. A switch to a higher plan is charged at once, pro rata for the rest of the current billing period; a switch to a lower plan is credited against the next invoice.

The Provider may offer the User a new price for the booked paid plan, for billing periods that begin after the new price takes effect. The Provider sends the offer by email at least 30 days before that date, stating the previous price, the new price and the date. The new price applies only if the User agrees to it expressly, in text form (for example by replying to the email); silence is not agreement. Until the new price applies, the User may cancel the paid plan at any time with effect at the end of the current billing period, as described in section 6; the email points this out. If the User does not agree, the paid plan continues at the previous price, and the Provider may cancel it as described in section 6. Amounts already paid for a billing period remain unaffected.

6. Term, renewal and cancellation

A paid plan runs for the billing period booked (one month or one year) and renews automatically by the same period unless it is cancelled before the end of the current period. There is no minimum term beyond the current billing period.

The User can cancel at any time with effect at the end of the current billing period: in the account, on the page "Cancel contracts here" (app.partiqon.com/contract/cancel, linked at the bottom of every page of the website), or by a declaration in text form to the Provider, for example by email to support@partiqon.com. If the User cancels in the account or on the page "Cancel contracts here", the User receives a confirmation of the cancellation by email at once. If the User cancels by email to support@partiqon.com, the Provider confirms receipt by email without undue delay. The plan remains available until the end of the paid period; a cancellation that has not yet taken effect can be undone in the account.

The Provider may cancel a paid plan with effect at the end of a billing period, by a declaration in text form that reaches the User at least 30 days before that end.

The right of either party to terminate for good cause remains unaffected.

6a. Right of withdrawal

Consumers have a statutory right of withdrawal. Its conditions, time limits and procedure, and the model withdrawal form, are set out in the withdrawal instructions; the confirmation email sent when a paid plan is booked contains them as well. A withdrawal can be declared online at app.partiqon.com/contract/withdraw, by email or by letter.

Before the order, the User requests that the service begins before the end of the withdrawal period. If the User then withdraws, the User pays a reasonable amount for the service provided until the withdrawal, and the rest of the amount paid is refunded. The right of withdrawal ends once the contract has been fully performed.

7. Intellectual property

All rights to the Platform itself, its software, structure, and design remain with the Provider. The User is granted a simple, non-transferable right to use the Platform for the duration of the contract, within the scope of the pricing tier booked.

Strategies, uploaded data, and configurations created by the User remain the property of the User.

9. Data protection

Information on the processing of personal data can be found in our Privacy Policy.

10. Changes to these Terms

The Provider may propose changes to these Terms with effect for the future. A change that concerns the main obligations of the parties (in particular the services of a plan, the prices, the term and the cancellation) or that otherwise alters the balance between service and payment becomes part of the contract only if the User agrees to it expressly. Section 5 sets out how a change of price is offered.

Other changes are limited to adaptations to a change in the law or in court decisions that affects a provision of these Terms, corrections of wording that do not change its meaning, and descriptions of new functions that are offered at no extra charge. The Provider notifies such a change in text form at least six weeks before it takes effect. The User may object to it until it takes effect. If the User does not object in time, the change is deemed accepted. The notification points out this consequence, the period and how to object.

If the User does not agree to a change that needs the User's express agreement, or objects to another change, the contract continues on the previous terms. The Provider may then cancel it: a paid plan as described in section 6, and use without a paid plan by a declaration in text form that reaches the User at least 30 days before the cancellation takes effect.

11. Final provisions

These Terms are governed by the laws of the Federal Republic of Germany, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). For consumers with habitual residence in another EU member state, mandatory consumer protection provisions of that state remain unaffected.

If the User is a business, a legal entity under public law, or a special fund under public law, the place of jurisdiction for all disputes arising from this contractual relationship shall be the Provider's place of business.

Should individual provisions of these Terms be or become invalid, the validity of the remaining provisions shall remain unaffected.
