Security & trust

Your schedule data never leaves your machine. That's the design.

SSIM Toolkit is a local desktop app. Commercial schedule data — the kind that makes a CISO read the policy before the product page — is read and analysed on-device, and stays there. There is no cloud to send it to.

  • Local-first by design
  • No data leaves your device
  • Deterministic · reproducible
  • Signed installers

Data flow

Where the data goes. And where it doesn't.

Inside your machine, your schedule file is parsed, validated and analysed into a typed, queryable schedule. Your schedule data stops at the boundary of your machine.Your machinewhere all the data work happensSchedule fileParse · validate· analyseDeterministicTyped, queryable scheduleyour data stops here
Everything inside the dashed line runs on your machine. Two small checks cross it; your schedules never do.

Your schedule files

Your schedule files stay where you put them — on your machine. They're opened, parsed, and analysed locally and never uploaded. We have no server that could read them, because there is no server in the path.

The pipeline

Parse → validate → analyse runs entirely on-device. The result is deterministic: the same file always produces the same answer, and every output traces back to a field in the spec — no model computes your numbers.

What we never see

  • Your schedule file contents · ever.
  • The parsed records, or any personal data inside them.
  • Your saved queries, bookmarks, or in-app notes.

How it's built

Local-first, by construction.

The controls an information-security review will ask about, in plain words.

  • Your data, on your machine

    Schedule files are read, parsed, and analysed entirely on-device. Nothing about your schedules is uploaded, mirrored, or processed on our servers.

  • The analysis runs on your machine

    Parse → validate → analyse runs on your computer, against the files you open. No step of it happens on our servers.

  • Deterministic by construction

    Same file in, same answer out. There is no model, no sampling, no guessing — every field is derived from the spec, and runs are reproducible.

  • Code-signing

    The macOS build is notarised and the Windows installer carries a verified publisher, so each installer verifies on its platform.
