Terms of Service

Last updated: July 14, 2026

1. Service and beta status

Open Backtest provides market replay, charting, simulated trading, backtesting, and related developer tools. During the closed beta, features may change, become unavailable, or contain errors without notice.

Beta data is provided for testing and is not guaranteed to be retained. Export anything you need to keep. Temporary Premium access may be changed or withdrawn before launch.

2. Accounts

You must provide accurate information, protect your credentials and passkeys, and promptly report unauthorized access. You are responsible for activity performed through your account.

3. Acceptable use

You may not use the service to:

  • break the law or infringe another person's rights;
  • probe, disrupt, overload, scrape, or bypass security and rate limits;
  • upload malicious code or attempt to access another account;
  • present simulated or historical results as guaranteed future performance.

4. Financial disclaimer

Open Backtest does not provide investment, legal, tax, or financial advice. Backtests and simulations have limitations, may contain inaccurate market data, and do not predict future results. Trading involves risk of loss.

5. Plans and billing

Paid plans, subscriptions, organization seats, prices, renewal periods, and cancellation terms are shown before checkout. Closed-beta Premium access may be promotional and does not guarantee a free public plan.

Purchases are governed by the Terms of Sale and processed by our merchant of record, Polar Software Inc., including invoicing, taxes, renewals, cancellation, and your withdrawal and refund rights.

6. Your content and our software

You keep ownership of content you submit. You grant us the limited rights needed to host, process, secure, and display it to operate the service. Open Backtest and its software, branding, and documentation remain protected by applicable intellectual-property laws.

7. Suspension and termination

You may stop using the service and request account deletion. We may restrict or terminate access to protect users, enforce these terms, comply with law, or end the beta. Some records may be retained where legally required.

8. Availability and liability

The beta is provided on an as-is and as-available basis. To the extent permitted by law, we do not guarantee uninterrupted operation, data accuracy, profitability, or preservation of beta data, and we exclude indirect or consequential losses.

9. Changes and contact

We may update these terms as the product and legal framework mature. Material changes will be announced in the application. Questions can be submitted through Get Help or the feedback form.

10. Governing law and disputes

These terms are governed by French law. If you are a consumer, you keep the mandatory protections of the country where you habitually reside and may bring proceedings before its courts. French consumers may also use the free consumer-mediation process described in the Terms of Sale.
