What’s the acceptable reporting retention period?

Acceptable reporting retention periods depend on analysis needs, compliance requirements, and storage constraints. Common practice retains detailed data for 1 to 2 years with aggregated data retained longer.

GDPR and similar regulations limit personal data retention but allow processing for legitimate business purposes including analytics. Anonymized or aggregated data faces fewer restrictions.

Balance retention against storage costs and privacy principles. Keep data long enough to support trend analysis and compliance needs. Purge data no longer serving legitimate purposes, especially detailed records containing personal data.
