The collected information is used together with the IP address of the request to monitor global software usage, user location (country only) as well platform statistics.
  • Crash reports: in the event of a malfunction of OpendTect, a crash report is generated. This crash report contains information that will help OpendTect’s developers to locate and fix the issue. The crash report is a text-file that contains:
    • Technical information about the crash.
    • Technical information about the computer such as amount of memory, number of computer cores and a unique system ID. The unique system ID is hashed, and cannot be used to identify the user.

All data is viewable in clear text before it is transmitted. No data is transmitted without the active consent of the user.
