Anonymous metrics
Language, operation type, duration, success state and HTTP status may be measured. Material names, item labels, lengths and quantities are not written to analytics records.
Visitor and location metrics
An anonymous first-party visitor identifier lasting one year is used to recognize the same browser. Approximate country and city are derived from the IP address using a local geolocation database on the server; the raw IP address is neither retained nor sent to an external analytics service. Private browsing, cleared cookies, another device, VPNs and mobile networks can affect the measurement.
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.
Language preference
Your selected language is remembered for one year in a first-party cookie containing only Turkish or English. The neutral address uses this preference first, then your browser language. You can change the language in the menu or clear the cookie in your browser.
Acquisition and usage metrics
Sample calculations and calculations using your own list are measured separately. Short source, medium and campaign codes from tagged links may be associated with a session. Full URLs, email addresses and production content are not added to these metrics. New calculations made while signed in as an administrator are marked as internal tests.
Production data is processed to provide the service; raw parts and stock content is not written to anonymous usage metrics.
