Does this tool upload my Access database?

No. The file is parsed entirely in your browser and is never sent anywhere. Nothing is uploaded, and the file is never opened in Access or by any database engine.

Is it safe to analyze a database with VBA macros?

Yes — the analyzer only reads table, column, and relationship structure. It never executes VBA code or macros of any kind, and never touches the parts of the file that would run them.

What do the complexity score and effort estimate mean?

They're an automated ballpark based on how many tables, columns, and relationships your database has — useful for a quick gut-check, not a quote. For an actual plan, request a free assessment.
