1. Who we are

Account registration and billing are covered by the CSS Software Privacy Policy. This document covers TRIM runtime and operational data only.

2. Scope

  • TRIM web portal — queues, workers, licences, settings
  • TrimWorker agents on your Windows PCs
  • TRIM notifications (email, in-browser, mobile push where enabled)

3. Australian data sovereignty

TRIM runtime data is hosted primarily in Sydney, New South Wales, Australia (BinaryLane, Mammoth Cloud, Next DC). TRIM uses a dedicated database separate from the CSS Software billing platform.

We do not sell your personal information or project metadata.

4. What we collect

Simulation metadata

Model names, file paths, run configuration, status, progress, and which staff member added a run. Paths may reveal project folder names on your network.

Workers and telemetry

Worker identity, heartbeats, GPU metrics, and incremental progress samples from TUFLOW log tails — aggregated for charts.

What stays on your infrastructure

TUFLOW model and result file contents are not uploaded to CSS servers. TRIM stores paths and operational metadata only.

5. How we protect your information

  • Tenant isolation per TRIM queue (subscription)
  • TLS for all browser and worker traffic
  • Role-based access and hashed worker secrets
  • Encrypted backups; databases not exposed publicly

6. Retention

Simulation and telemetry data is retained while needed to operate your queue. Simulation history and audit events are kept for the operational life of the subscription plus 24 months. Security logs are retained up to 24 months.

7. Third parties

  • Brevo — transactional email
  • Google FCM / Apple APNs — mobile push (if enabled)
  • Your organisation's administrators — queue visibility for authorised staff

8. Your rights

Access, correction, and complaints follow the same process as the CSS Software Privacy Policy. Contact us via our contact form.
