Temporary files
Uploaded and generated files are automatically removed within 24 hours by default.
Calculation results
Temporary server results used for downloads are retained for 12 hours by default; the administrator may configure 1-72 hours.
Analytics records
Only anonymous aggregates and technical status data are retained. New records do not store raw parts or stock lists.
Active calculation recovery
The job identifier and calculation inputs are held temporarily in the tab session so a calculation can be followed after a page refresh. The record is removed after the result is received; records older than 12 hours are removed on the next access. This is separate from optional 30-day device storage.
Optional device storage
Keep my list and settings on this device is off by default. When enabled, the parts list, stock list and settings stay in this browser for 30 days after the last save; expired data is removed on the next visit. Delete from this device removes the copy. This local copy is separate from temporary server files; starting a calculation sends the required inputs to the server. Leave this option off on shared devices.

Production data is processed to provide the service; raw parts and stock content is not written to anonymous usage metrics.
