Box & Whisker by TCViz is a Power BI custom visual developed by TCViz (Tino Callarisa). This policy describes how data is handled when you use it.
The visual does not collect, transmit or store any data. Every calculation — quartiles, whiskers, outliers, density, the statistics table — happens inside Power BI, on the data of your report.
The visual declares no network privileges ("privileges": []), so Power BI does not let it make any web request.
The icon on the start screen is bundled inside the visual.
The Guide and Product page links on the start screen ask Power BI to open those pages in your browser, only when you click them; Power BI opens them in your browser (Power BI Desktop asks first). The visual sends nothing.
No cookies and no browser storage. Formatting settings are saved in your report by Power BI, like those of any visual.
To know whether you have a Pro licence, the visual asks Microsoft's licensing API in Power BI (IVisualLicenseManager). TCViz receives
no data from this check. See the Microsoft Privacy Statement.
No analytics, tracking or advertising.
