These general terms (the “Terms”) govern access to the Backtrex platform and the purchase of paid subscriptions. They are entered into between you and Stemya Tech, a sole proprietorship registered under SIREN 881 895 478, with its registered office at 520 Route de Trévoux, 01600 Reyrieux, France. Payments are collected by Paddle.com Market Limited, acting as reseller (Merchant of Record). By creating an account, you accept these Terms in full.
Purpose of the service
Backtrex is an online platform for backtesting trading strategies. It lets you build strategies visually, test them on historical data and export the corresponding code. The service is a simulation tool intended for educational purposes: it is not investment advice, a personalised recommendation, or an inducement to invest.
Access to the service
Access requires an account with a valid email address. You are responsible for keeping your credentials confidential. The features available depend on your plan (Free, Pro or Max).
Conditions of use
You agree to:
- Use the service for its intended purpose (backtesting strategies)
- Not attempt to circumvent the limits of your subscription plan
- Not use the service for unlawful or fraudulent purposes
- Not reproduce, decompile or create derivative works from the service
- Not deliberately overload the infrastructure
Subscriptions, prices and payment
Paid subscriptions are offered on the following terms:
- Displayed prices are exclusive of tax. The applicable tax is determined and collected by Paddle based on your country of residence and is added to the displayed price; the exact tax-inclusive amount is shown to you before you confirm your order.
- A 7-day free trial may be offered on the Pro plan. It requires a payment method and automatically converts into a paid subscription at the end of the trial, unless you cancel before that date.
- Payment is made by card at the start of each billing period, through Paddle's secure platform. No card details are stored by Backtrex.
- The order becomes binding when payment is confirmed on the Paddle order page. A confirmation setting out your subscription, its price and its renewal date is sent to you by email, together with the corresponding invoice.
- If a payment fails, access to paid features may be suspended until the situation is resolved, after prior notice.
Term, renewal and cancellation
The subscription runs for the term selected at checkout and renews automatically:
- The subscription is taken out for one month or one year depending on the plan chosen, and renews automatically for an identical term at the then-current price, unless cancelled.
- You may cancel at any time, without reason or charge, from Settings > Subscription > Cancel in the application, or from the Paddle customer portal. Cancellation takes effect at the end of the current period.
- In accordance with article L. 215-1 of the French Consumer Code, you are notified by email — no earlier than three months and no later than one month before the deadline for rejecting renewal — of your right not to renew an annual subscription.
- You keep access to paid features until the end of the period already paid for. The account then switches automatically to the Free plan; your strategies and backtests remain saved.
- Any price change is notified to you at least thirty days before it takes effect and entitles you to cancel free of charge before that date.
Right of withdrawal
You have fourteen (14) days to exercise your right of withdrawal, without giving any reason and without penalty.
- The period runs from the day the contract is concluded, that is, the day you subscribe — including where the subscription starts with a free trial.
- To exercise it, notify us of your decision by an unambiguous statement sent to contact@backtrex.com, or use the model form set out below. We acknowledge receipt without delay on a durable medium.
- We refund all sums paid no later than fourteen (14) days after receiving your decision, using the same payment method you used for the order, at no cost to you.
- If you expressly asked for the service to begin before the end of the withdrawal period, you remain liable for an amount proportionate to the service supplied up to the point you informed us of your decision. Nothing is due where no payment has been taken, in particular during a free trial.
- The right of withdrawal arises when the contract is concluded: an automatic renewal does not open a new period.
Model withdrawal form
You may copy, complete and send us the form below. Using it is not mandatory.
To Stemya Tech — 520 Route de Trévoux, 01600 Reyrieux, France — contact@backtrex.com I hereby give notice that I withdraw from my contract for the supply of the following service: — Subscription ordered on: …………………………… — Name of consumer: …………………………… — Address of consumer: …………………………… — Email address linked to the account: …………………………… — Date: …………………………… — Signature (only if this form is notified on paper)
Statutory guarantee of conformity
The service supplied is a digital service within the meaning of articles L. 224-25-1 et seq. of the French Consumer Code. Accordingly:
- We must supply a service that conforms to the contract and to the qualities you may legitimately expect, and we are liable for any lack of conformity arising throughout the supply period.
- Where the service does not conform, you may require it to be brought into conformity free of charge and within a reasonable time. If that is impossible, refused or delayed, you may obtain a price reduction or termination of the contract with a refund.
- These guarantees apply regardless of any goodwill gesture we may make. Nothing in these Terms may exclude or limit them.
Intellectual property
The Backtrex platform, its source code, design, algorithms and content are the exclusive property of Stemya Tech. The strategies you create belong to you. Exported code (Pine Script, MQL5) is generated by our proprietary algorithms and licensed to you for your personal use.
Limitation of liability
Backtrex is a simulation tool. To the extent permitted by law, we are not liable for:
- Financial losses resulting from trading decisions based on backtest results, the user remaining solely responsible for their trades
- Temporary unavailability of the service for scheduled maintenance or due to force majeure
- Inaccuracies in historical data supplied by third-party providers, where these are outside our control
- Divergences between simulated results and actual performance in live market conditions
In any event, our contractual liability is capped at the amounts you actually paid during the twelve months preceding the triggering event. Nothing in these Terms excludes or limits our liability for wilful misconduct or gross negligence, nor the statutory guarantees owed to consumers.
Account deletion and suspension
You may delete your account at any time from your settings. Stemya Tech may suspend or delete an account in the event of a established breach of these Terms, after prior notice stating the reason and allowing a reasonable time to remedy it — except where the security of the service is seriously at risk or where required by law. Deleting an account does not waive any refund owed to you.
Changes to these Terms
Stemya Tech may amend these Terms to reflect legal, technical or product changes. Any material change — in particular to price, term or the essential characteristics of the service — is notified to you by email at least thirty (30) days before it takes effect. You may then cancel free of charge before that date; otherwise the new Terms apply from the date they take effect. The Terms applicable to your contract are those in force on the day you subscribed.
Complaints and consumer mediation
Any complaint may be sent to contact@backtrex.com. We undertake to respond within fourteen (14) days.
In accordance with article L. 612-1 of the French Consumer Code, if your complaint has not been resolved to your satisfaction, you may refer the matter free of charge to a consumer mediator with a view to an amicable settlement, within one year of your written complaint.
Governing law and jurisdiction
These Terms are governed by French law. As a consumer, you retain the benefit of the mandatory provisions of the law of your country of habitual residence. In the event of a dispute, you may bring proceedings before the courts of your domicile or those of Stemya Tech's registered office, at your choice; we may only bring proceedings against you before the courts of your State of residence.
