There are two different retention periods - one for pending identifications and one for completed identifications.
When an identification is created for a user, the resulting Ident-ID is valid for 90 days.
Once an identification is completed, the result data is stored for 90 days.
This is the maximum period and is configured by default, but can be reduced upon request. Additionally, you can delete data using the API, for example after retrieving the result file. Deletion is final and cannot be reversed under any circumstance.
