By default, the Event Platform deletes instrumentation data after 90 days. In order to retain data longer, the fields must be added to the sanitization allowlist.

All the fields can be added to the allowlist except for the user name, which must be left off so that it is still deleted after 90 days. (Hashing the user name is not sufficient since it would be possible to retrieve the original name by matching the timestamp of the report submission event with the timestamp of the filed report.)
