Browser processing
Files uploaded through the browser application are processed on a Hetzner server in Germany. Each browser tab has an isolated working session. Saved comparisons belong to the signed-in workspace.
DATA HANDLING
Your files. A clear processing path.
STEP revisions are processed on PartDatum’s server in Germany. Review storage, access and deletion before starting a comparison.
Retention
Working-session files expire within 24 hours or when that session ends. Saved comparisons and their STEP files expire after 30 days. “Keep reports only” omits STEP files from saved history; temporary processing copies still follow the session rule. Pilot expiry does not extend deletion dates.
Deletion
Deleting a comparison removes its record, saved sources, reports and shared links from the active database and application-level backups, and closes associated working sessions. Ending a session removes temporary files; it does not remove saved history. Provider disk snapshots may retain older copies until rotation; individual files cannot be erased from those snapshots instantly.
Access
Workspace members can access their workspace results. Recipients of active shared links can view the shared record. PartDatum’s authorised operator has administrative access for service operation. Hetzner provides the hosting infrastructure.
Export-controlled data
Use permitted data for the web service. Export-controlled and classified data require a separate written arrangement.
CAD data and AI
The application does not send CAD files to an AI service or use them for model training. Geometry calculations are performed by the CAD engine.
Feedback and this website
Application feedback is stored separately from comparisons and is visible to the administrator. Deleting a comparison does not delete feedback. The interest form collects your email and contact permission, plus company, role, industry and CAD system if provided. The website hosting provider also processes technical request data.
