Data Dumps
Ingest your own GDPR and app exports into DuckDB, then explore them locally.
The exports I have a legal right to arrive as zips that are awkward to open one by one. A spreadsheet is enough for a single CSV. Several years of takeouts is a different problem.
Data Dumps puts those exports into one warehouse on this machine and opens them in a local dashboard. Nothing is hosted. The files stay here.
Once more than one source is loaded, I can compare them. Phone numbers, IPs, ads, and identity documents stay out of the tables I actually query.
I am running it on my own exports, and adding a source when I request the next dump.
