How We Handle Data

Your simulated trades, drawings, and journal logs remain strictly inside your browser's local storage. We do not store your proprietary strategies on remote servers. Like standard modern web apps, third-party cookies (e.g. Google Analytics) are used to maintain platform stability.

We do not sell get-rich-quick signals or automated black-box bots. Backtest Trading Lab is founded on E-E-A-T principles (Experience, Expertise, Authoritativeness, and Trustworthiness). Every replay and calculation tool runs locally in your browser with instant client-side execution, complete privacy, and total adherence to standard institutional formulas.
