**Data Integrity and Normalization**\
We preserve raw data as closely as possible to the original source to ensure accuracy and transparency. Unlike many providers that pre-normalize datasets, our approach keeps the underlying signals intact. Normalization is applied only within our KPI forecasting models, where it is necessary to align disparate signals into a unified framework for predicting company performance. This way, users always have access to both the raw, unadjusted data for direct analysis and the normalized outputs used in KPI forecasts.
