1. Agreement and service
These terms form an agreement between you and Matheus Dümpelmann when you access or use QuantLions. You must be legally capable of entering this agreement and use the service only in accordance with applicable law.
QuantLions provides infrastructure for historical strategy research. Features may include strategy configuration, backtesting, analytics, visualizations, saved research, usage estimates, and integrations such as the QuantLions app for ChatGPT.
2. Important research and risk boundary
QuantLions provides general research tools and historical information. It does not provide investment advice, portfolio management, brokerage services, trade execution, or a personal recommendation. Outputs are not presented as suitable for any particular person.
Backtests are hypothetical, depend on data and assumptions, and do not predict future performance. They may omit or simplify market impact, liquidity, slippage, taxes, outages, changing market conditions, and other real-world constraints. Losses, including total loss, are possible.
You remain responsible for interpreting research, independently verifying results, and making every trading or investment decision.
3. Accounts and acceptable use
Provide accurate account information and protect your credentials. You are responsible for activity conducted through your account. Notify us promptly if you suspect unauthorised access.
Do not misuse the service, bypass limits, disrupt infrastructure, scrape protected systems, introduce malicious code, access another person’s data, or use QuantLions for unlawful or deceptive activity. We may restrict access to protect users, infrastructure, or legal compliance.
4. Plans, credits, and billing
Plans may include a monthly credit allowance. Before a chargeable backtest is submitted, QuantLions displays an estimate based on the selected configuration and available history. The final charge follows the execution actually accepted under the applicable pricing rules.
Unless the checkout states otherwise, monthly credits do not roll over, have no cash value, and cannot be transferred. Cached results may be returned without another research charge. Current prices, taxes, renewal periods, and cancellation conditions are shown before purchase.
5. Research content and intellectual property
You retain rights you hold in strategy descriptions and other content you submit. You permit QuantLions to process that content as necessary to provide, secure, and improve the requested service. Do not submit material you lack the right to use.
QuantLions and its licensors retain rights in the platform, software, visual design, documentation, and datasets, excluding content owned by users or third parties.
6. Availability and changes
We work to keep the service reliable but do not promise uninterrupted or error-free operation. Market data can be delayed, incomplete, adjusted, or incorrect. We may change or discontinue features, with appropriate notice where required.
7. Liability
Nothing in these terms excludes liability that cannot legally be excluded. Subject to mandatory law, QuantLions is not responsible for trading losses, decisions based on research outputs, indirect losses, or failures outside its reasonable control.
