SenSym Data Factory

Generates synthetic datasets from distributions you choose — every value traceable to a real, visible parameter, never a hidden model. Runs entirely on this machine: no account, no server, no telemetry.

• Broad, deep synthetic data — a large registered type catalog spanning numeric, temporal, identifiers, categorical, geo, text, images, speech, and declared causal structure.
• Eight export formats: CSV, TSV, Parquet, SQLite, JSON, JSONL, SQL, and Excel.
• Scenario Mode drafts a recipe from a plain-language description, with an offline template tier that needs no setup at all.
• Every export ships a data dictionary and a provenance record naming exactly how it was made.

First launch on macOS

SenSym Data Factory is signed with a real Apple Developer ID and notarized by Apple — every release build is submitted to Apple's notarization service and confirmed clean before it's published (verified directly against the built .dmg before each release: spctl -a -vv reports accepted, source=Notarized Developer ID, and codesign --verify --deep --strict passes on the full app, including the bundled Python engine).

Opening it#

1. Drag SenSym Data Factory.app from the mounted .dmg into Applications.
2. Double-click it in Applications, same as any other Mac app.

The first time you open anything downloaded from the internet, macOS shows a one-time dialog naming the app and asking you to confirm — click Open. That's it; there's no right-click workaround needed, no Privacy & Security detour, and no "unidentified developer" warning.

If you see a different warning#

A signed, notarized app should never show "Apple could not verify this app is free of malware" or "this app is damaged" — if either appears, something is genuinely wrong with that specific download (most likely it didn't finish, or was altered in transit), not with the app itself. Don't work around it — instead:

1. Verify the .dmg's checksum against the one published alongside the release (shasum -a 256 <the .dmg>, compared against the published .sha256 file). A mismatch means the download is genuinely corrupted or incomplete — delete it and download again.
2. If the checksum matches and you still see a warning, that's worth reporting — it would mean this specific build's notarization didn't take for some reason.

Command-line install#

install.sh (linked from the download page) does all of the above automatically: downloads the .dmg, verifies its checksum, and installs it — real verification before anything gets copied into /Applications, not a substitute for it.
