DataGenius BI is architected with strict client-side data isolation. When you upload Excel (.xlsx, .xls) or CSV documents, all mathematical evaluations, anomalies, and charts are generated entirely within your browser memory using local JavaScript execution. We do not store, copy, inspect, or retain your spreadsheets on our web servers.
We partner with third-party vendors and advertising networks (such as Google and Adsterra) to serve non-intrusive ads when you visit our site. These companies may use cookies to serve advertisements based on prior visits to this or other websites. Users may opt out of personalized advertising by visiting Google Ads Settings.
If you optionally input your own Google Gemini API key for advanced generative insights, the key is saved exclusively in your personal browser's local memory (`localStorage`). It is never transmitted to our backend databases.
Like standard web platforms, we may log anonymous technical parameters (browser type, device type, referring URLs) purely to maintain site stability and prevent automated DDoS attacks.
