Terms of Service

Last updated: March 2026

1. Acceptance of Terms

By accessing or using Portfolio Backtester ("the Service"), you agree to be bound by these Terms of Service. If you do not agree, do not use the Service.

2. Description of Service

Portfolio Backtester is a tool for simulating historical portfolio performance using dollar-cost averaging. The Service uses historical market data and is intended for educational and informational purposes only.

3. Not Financial Advice

The Service does not provide financial, investment, tax, or legal advice. Past performance does not guarantee future results. All backtesting results are simulations based on historical data and should not be used as the sole basis for investment decisions. Consult a qualified financial advisor before making investment decisions.

4. User Accounts

You are responsible for maintaining the security of your account credentials. You must provide accurate information when creating an account. We reserve the right to suspend or terminate accounts that violate these terms.

5. Acceptable Use

You agree not to:

  • Use the Service for any unlawful purpose
  • Attempt to gain unauthorized access to the Service or its systems
  • Abuse API rate limits or scrape data programmatically
  • Resell or redistribute data obtained from the Service

6. Premium Features

Certain features (extended backtesting periods, CSV export) require a Premium subscription. Pricing and availability are subject to change. Free trial access for early users may be revoked at our discretion.

7. Data Accuracy

Historical market data is sourced from third-party providers. While we strive for accuracy, we do not guarantee the completeness or correctness of any data. The Service is provided "as is" without warranties of any kind.

8. Limitation of Liability

To the maximum extent permitted by law, Portfolio Backtester and its operators shall not be liable for any indirect, incidental, or consequential damages arising from your use of the Service, including but not limited to financial losses from investment decisions.

9. Changes to Terms

We reserve the right to modify these terms at any time. Continued use of the Service after changes constitutes acceptance of the updated terms.
