If I do my audit on my phone/computer and save it but do not submit it to MEG, will that appear anywhere else?

No, it will not. Unsubmitted audits will only save locally to the device or desktop you used during the data collection.

Unsubmitted audits will not be saved to the main system. Instead, they will only be stored locally on the specific device or desktop used during data collection. This means the information remains on that device until you officially submit the audit, after which it will be uploaded to the system.
