// FAQ
Common questions
What file formats are supported?▼
Free: GeoJSON, KML, WKT, CSV. Pro Web adds Shapefile (.shp bundled in .zip) and Excel (.xlsx) for both input and output. Desktop adds true folder-level batch processing and automatic reprojection from any CRS to WGS84.
Is my data private? Do you store my files?▼
100% client-side across all browser tiers. Files are parsed and converted entirely in your browser using JavaScript — nothing is uploaded to any server. The Desktop app is fully local.
How does the 100-feature free limit work?▼
You can load any size file — GeoFlow processes it all but outputs only the first 100 features, clearly labelled. You get 25 runs per day (2,500 features total). The counter resets at midnight local time and is tracked in your browser.
What do the geometry tools do?▼
Pro geometry tools include: Fix winding order (reverses coordinate rings so SQL Server geography renders correctly), Remove duplicate vertices (cleans redundant points), Force MultiPolygon (wraps all Polygon types for consistent schema), and Simplify (reduces vertex count with adjustable tolerance — useful for large county/state boundaries).
geography vs geometry — what's the difference?▼
SQL Server GEOGRAPHY stores lat/lon and works with the SSMS map viewer. GEOMETRY stores lon/lat (X/Y order). GeoFlow automatically handles the coordinate flip for geography — so your polygons appear in the right place in SSMS.
Can I cancel my subscription?▼
Yes, cancel anytime from your account page. Access continues until the end of your billing period. GeoFlow is sold AS-IS with no refunds — use the free tier to evaluate before purchasing.
How do license keys work?▼
After subscribing, a license key is generated and emailed to you. Create a free GeoFlow account, go to your account page, and enter the key to unlock your tier. Keys activate on up to 2 devices.
