Privacy Policy — SheetViz Maps
Last updated: June 2026
Overview
SheetViz Maps is a Microsoft Excel add-in provided by SheetViz LLC. This policy describes how SheetViz Maps handles your data.
Data processing
When you use SheetViz Maps, address data you enter is sent to the OpenStreetMap Nominatim geocoding service to convert addresses into geographic coordinates (latitude and longitude). This is the only data transmitted outside your Excel workbook.
What we do not collect
SheetViz Maps does not collect, store, or transmit your personal information, spreadsheet data, or usage analytics. There are no user accounts, no tracking cookies, and no telemetry.
Data storage
All map data — including addresses, coordinates, pin formatting, and map settings — is stored exclusively in your Excel workbook within your Microsoft 365 environment. SheetViz LLC has no access to your workbook data.
Third-party services
Address geocoding is performed by the OpenStreetMap Nominatim service (nominatim.openstreetmap.org). Their usage policy is available at operations.osmfoundation.org/policies/nominatim/. Map tiles are provided by OpenStreetMap contributors, Carto, and Esri.
Advertising
SheetViz Maps does not display advertisements or share data with advertisers.
